* bseamplifier.cc: fixed whitespaces and extra variables.

* bseamplifier.cc: fixed bug #474244, based on a patch by Stefan
Westerfeld which changes multiplied control signals to not get
halved as we do with summated signals to constrain the range to [0,1].
compatibility code handles value adjustments for bse files <= 0.7.1.

* bseamplifier.cc:
property_changed(): fixed missing property notifies and compat
property handling wrg to audio levels and ctrl_balance, fixes
bug #474332.

* artscompressor.cc: Moved constants to bse/bsemath.h.

* artscompressor.cc: Replaced log() and exp() calls by constants where
possible, that is for all cases where the argument is constant, too.

* bsenoise.cc: Nullify noise_table pointer after deleting it, so that
it never points to deleted and invalid memory. This just makes
debugging easier in case something goes wrong later, and doesn't
change the current behaviour.

* bsenoise.cc: Added deterministic random number generator (from
rapicorn) and use it if --bse-disable-randomization is active.

* bsenoise.cc: Bugfix: Generate a noise table with the same size,
instead of generating smaller noise tables for smaller block sizes.
This means that the noise will no longer degenerate for small block
sizes.
Generate just one single noise table, instead of one-per-instance.

* updated licenses to GNU Lesser General Public License version 2.1
with permission from Stefan Westerfeld where required.

* artscompressor.idl, artscompressor.cc:
relicensed under GNU Lesser General Public License version 2.1
with permission from Matthias Kretz and Stefan Westerfeld.

* davguitar.c, davxtalstrings.c: updated patent license notice.

* davxtalstrings.c: Added a small random number generator (from
rapicorn) to deterministically generate random values if the option
--bse-disable-randomization is used. This makes it possible to bring
this module under test properly.

* bsesummation.idl, bsesummation.cc: added audio-diff output channel
which provides a difference signal between it's two output signals.

* davxtalstrings.c:
* davsyndrum.c:
* davcanyondelay.c:
* bseiirfilter.c:
* davorgan.c: Spelling fix: the unit for frequencies is spelled
"Hertz" (not "Herz").

* davxtalstrings.c:
dav_xtal_strings_init(): initialize transpose_factor to 0 to uncover late update bugs.
dav_xtal_prepare(): update config.transpose_factor, using BseSource's musical_tuning.

* davorgan.c:
dav_organ_init(): initialize transpose_factor to 0 to uncover late update bugs.
dav_organ_update_modules():
dav_organ_prepare(): update config.transpose_factor, using BseSource's musical_tuning.

* bsequantizer.idl:
* bsequantizer.cc: improved blurb, support fractional quantization
steps. adjusted steppings. use nearbyint() for rounding to avoid
buglets around 32bits.

* bsequantizer.idl: use quantizer.png as icon.

* icons/quantizer.png:
* icons/quantizer.xcf: changed to updated version by Hanno Behrens.

* icons/quantizer.xcf: added icon by Hanno Behrens <pebbles@schattenlauf.de>.

* davorgan.c (dav_organ_init):
* davxtalstrings.c (dav_xtal_strings_init): fix missing initialization
of transpose_factor, fix found by Stefan.

* bsesequencer.c:
* bseiirfilter.c:
* davorgan.c:
* davsyndrum.c:
* davcanyondelay.c:
* davxtalstrings.c: adapt to new tuning relative note API, add a
warning to tooltips that informs about the musical tuning specific
interpretation of note properties.
use bse_source_prepared_musical_tuning() once sources are prepared
and if possible.

* davxtalstrings.c (dav_xtal_strings_class_init):
* davsyndrum.c (dav_syn_drum_class_init): added i18n markup and
adapted some tooltips.

* davcanyondelay.c (dav_canyon_delay_class_init): added i18n markup and
adapted some tooltips.

* Makefile.am, Makefile.plugins: rewrote rules to compile multiple
C++ plugins into a single .so binary.

* *.[hc]: removed plugin names.

* bsequantizer.cc: use dtoi32 for quantisation effects, which gives
round-to-nearest, i.e.
{-1.5 -> -1 <- -0.5}, {-0.5 -> 0 <- +0.5} and {+0.5 -> +1 <- +1.5}.

* bsequantizer.idl, bsequantizer.cc: added bit-quantization module.

* bseblockutils.cc: provide "SSE" as impl_name.

* davorgan.idl:
* davorgan.cc: Copied from davorgan.c, to start porting DavOrgan to
C++.

* davorgan.c: Added a reset() function for the organ modules, which
explicitely initializes the phases. It initializes them to zero if
--bse-disable-randomization is active, and randomly otherwise. This
replaces the old behaviour to initialize the phases somewhat randomly,
by simply not implementing reset() at all.
See also bug #364041, which is fixed by this change.

* bsesummation.idl:
* bseadder.c: fixed documentation typo.

* bseblockutils.cc: Only optionally produce output during the filter
implementation test.

* bseblockutils.cc: Use fir_test_filter_sse() within test_resampler2()
hook, to test that the SSEified FIR filter routines work as expected.

* bseblockutils.cc: access Resampler2::create_impl() via derivation.

* bseblockutils.cc: Provide resampler factory method, so that an SSE
resampler will be used when beast detects SSE instructions.

* davorgan.[hc]: Add transpose and fine_tune settings, just like they
can be found in the oscillator code. Fixed a few minor i18n bugs in
property translation markup.

* davxtalstrings.[hc]: Add transpose and fine_tune settings, just like
they can be found in the oscillator code. Fixed a few minor i18n bugs
in property translation markup.
Use gdouble precision to store transposed frequency within the engine
module data structure.

* davsyndrum.c (dmod_process): fixed ratio read-out. spotted by Stefan.

* davsyndrum.c (dav_syn_drum_update_modules): It is important to
update sample rate dependant parameters in the "params" struct within
the object, because the "params" struct within the object will be used
by dav_syn_drum_context_create to initialize the state for the
modules. This fixes #337703.

* bseblockutils.cc: Minor optimizations, introduced a few LIKELY()
calls to indicate what usually should be the case, and improved some
comments.

* bseblockutils.cc (range, range_and_square_sum): Use SSE functions to
calculate the minimum/maximum and the vector sum after the main loop.
I benchmarked it on AMD64 and Pentium-M, and its faster on both.

* bseblockutils.cc: define _mm_extract_ss() for convenience.
square_sum(): use SSE functions to calculate the vector sum
after the main loop.

* bseblockutils.cc: Implement new sub, mul, range, square_sum,
range_and_square_sum functions using SSE.

* bseadder.c: deprecated this plugin (use BseSummation instead).

* *.c: adapted to new BSE_REGISTER_OBJECT*() macro args.

* Makefile.am:
* Makefile.plugins:
* icons/Makefile.icons: build and install BseSummation.

* bsesummation.cc:
* bsesummation.idl: CVS copied here from bse/.

* icons/summation.png:
* icons/summation.xcf: CVS copied here from bse/icons/.

* bseamplifier.cc:
* Makefile.plugins:
* Makefile.am: added BseAmplifier to plugins/.

* icons/ampctrl.png:
* icons/ampctrl.xcf: CVS copied here from bse/icons/.

* bseamplifier.idl:
* bseamplifier.cc: CVS copied here from bse/.

* bseblockutils.cc: fixed inner variable declarations which erroneously
shadowed the real variables declared in an outer scope. this fixes mis-
calculations of the add() and scale() SSE routines. fix from Stefan
Westerfeld.

* bseblockutils.cc: fixed alignment check logic in ::scale(), this
fixes segfaults on unaligned blocks.

* plugins/bseblockutils.cc: new SSE-only plugin which replaces the FPU
block utils provided by BSE with SSE variants.
SSE variants are so far supplied for add() and scale() based on SSE
code by Stefan Westerfeld.

* Makefile.am: propagate PLUGIN_FLAGS, FPU_FLAGS and SSE_FLAGS from
configure.in to the various plugin types.

* plugins/Makefile.plugins: updates.

* Makefile.am: install all plugins into the same dir. generate .FPU.
and .SSE. plugins.

* Makefile.plugins: updates.

* Makefile.am: added a rule "refresh-Makefile.plugins:" to rebuild the
Makefile.plugins manually, without listplugins.sh. removed cruft about
generted enum headers for C plugins. build plugins twice now, once in
an ordinary "+PLAIN" version, and once with SSE_FLAGS as "+SSE". the
sse variant is built conditionally. install plugins in "plugins+PLAIN/"
and "plugins+SSE/" directories. lots of cleanups in the generation rules.

* listplugins.sh: removed, generation logic was moved into Makefile.am.

* Makefile.plugins: manual update.

* freeverb/denormals.h (undenormalise): fix macro name.

* freeverb/denormals.h: implement undenormalise() as BSE_FLOAT_FLATTEN().
this is faster and circumvents a gcc bug/optimization that rendered the
roomsize and damping parameters useless.

* evaluator/: Building of this plugin has been completely disabled
because it never left pre-prototype stage, and it contains mallicious
code that gets into the way of normal program operations (such as
printf() statements that spew into the stdout channel).

* Makefile.am: removed evaluator/ from SUBDIRS.

* evaluator/Makefile.am: disabled build rules.

* standardguspatchenvelope.cc: License reverted to LGPL since the code
is not really "based on" Timidity++.

* standardguspatchenvelope.cc: wave chunk lookups currently are done
with a hardcoded velocity of 1.

* standardguspatchenvelope.cc: License clarification: as I wrote the
code by looking at timidity's code, it is GPL (like timidity), not
LGPL.

* standardguspatchenvelope.cc: Improvements in envelope rate handling,
which make the envelope sound more like timidity.
If there is no envelope in the GUS patch, then pass sample data
literally.

* standardguspatchenvelope.cc: Fix initialization bugs: added a
constructor to initialize some members variables, and properly
initialize others upon reset().
Added support for the retrigger input signal (though currently this is
not necessary, as the current midi code will never retrigger a voice
within a block; only block boundary retrigger in combination with
reset() is used).

* removed obsolete .h C++ headers.

* adapted sources to compile against .hh C++ headers.

* standardsaturator.idl: move saturator into the distortion submenu.

* standardguspatchenvelope.cc: Don't assume that in the attack phase,
the envelope rate is always positive, and in the decay phase always
negative. Instead, look at the offsets of adjacent envelope points to
figure out the sign for rate. Fixes: problems with freepats fretless
bass envelope and probably others.

* standardguspatchenvelope.cc: Implemented chunk specific envelope
code, inspired by timidity. Currently, its not yet finished: some
envelopes from the FreePats set are treated the way I think they are
correct (Piano), some are not (FretlessBass).

* standardguspatchenvelope.idl:
* standardguspatchenvelope.cc: Retrieve envelope from chunk specific
xinfos string.

* standardguspatchenvelope.cc: Fixed code of the last change.

* Makefile.am:
* Makefile.plugins: Added standardguspatchenvelope.idl.

* standardguspatchenvelope.idl:
* standardguspatchenvelope.cc: The GUS Patch format is a mono format,
so we only need a mono input for envelope. Moved to the Misc category.

* standardguspatchenvelope.idl:
* standardguspatchenvelope.cc: Added preliminary implementation of the
envelope for the GUS Patches. This version doesn't yet use the data
from the wave chunks. However, it eliminates clicks at the start/end
by adding a small ramp, and already has mostly the interface that the
final version will have.

* standardsaturator.idl:
* standardsaturator.cc: new saturator module, supporting various
saturation types.

* Makefile.am: added standardsaturator.idl, added --macro to sfidl
invokation to simlpify type registrations in plugins.

* icons/compressor.xcf: updates to support saturation module icon.

* saturate.png: saturation module icon.

* moog.png: moog filter module icon.

* davsyndrum.c (dav_syn_drum_update_modules): don't keep sample rate
specific fields in the BSE object.

* davbassfilter.cc: fixed inverted trigger condition.

* davbassfilter.*:
* davchorus.*: moved modules into Bse:: namespace.

* artscompressor.cc: include bse/bsemath.h instead of math.h
and use BSE_LN2.

* bseiirfilter.c (bse_iir_filter_update_modules): disabled
debugging printout.

* artscompressor.cc: Keep output_db property fixed when auto_output is
active. Implemented editable_property() method, to make the user aware
of this.

* davbassfilter.[ic]*: implemented automation for cutoff_perc,
reso_perc, env_mod and env_decay.

* artscompressor.idl: Improved auto_output tooltip.

* *.idl: removed SFI_PARAM_ prefix from option constants.

* bseiirfilter.c: fixup enum registration, according to recent
BseExportNodeEnum changes.

* artscompressor.idl: Adjusted the threshold [dB] range to [-100,0],
which is what was previously valid. This is due to compatibility;
from a musicians point of view, thresholds below -30 dB or so probably
don't make too much sense.
Auto output is now a gui only property, since there are problems with
the beast storage mechanism when it comes to properties which depend
on each other.

* artscompressor.cc: Added makeup gain correction factor (from jamin
source), which should prevent over correction in automatic output
amplification. Added a few CLAMPs to ensure that properties converted
from old files will fit into our ranges.

* artscompressor.cc: Implemented more sensible half-life time computation,
which handles corner-cases (very small attack/release times) better.

* davbassfilter.idl:
* davbassfilter.cc: added trigger input channel.

* davbassfilter.cc: don't reset coefficients in reset().
slight renames, removed temporary from class, fixed envelope
counter in process() and removed useless code.

* artscompressor.idl artscompressor.cc: Cleanup: new documentation,
volume related properties are dB now, compressor ratio is given as x:1
and not as fraction (more intuitive), new property auto_output allows
adjusting the output amplification automatically. Removed stereo
version completely in favour of an implementation which handles both,
mono and stereo, in one module. Moved into the Bse namespace.

* icons/compressor.png:
* icons/compressor.xcf:
* icons/compressor2.png:
* icons/compressor2.xcf:
* icons/sample+hold.png:
* icons/sample+hold.xcf: new icons submitted by
Artem Popov <tfwo@mail.ru>.

* artscompressor.idl: use new compressor icons.

* bsecontribsampleandhold.idl: use new sample+hold icon.

* bsenoise.[hc]: Obsolete, removed.

* bsecontribsampleandhold.idl:
* bsecontribsampleandhold.cc: added new plugin from Artem Popov.
added license information and changed namespace to Bse::Contrib.

* bsesimpleadsr.c (simple_adsr_reset): added missing reset method,
to restart envelope phase and reset trigger/gate history.

* *.[hc]*: fixed if_reject() and if_expect() usage.

* *.h, *.c, *.cc: globally renamed GSL Engine to BSE Engine.

* *.c: include bseengine.h.

* bsesimpleadsr.c (simple_adsr_process): guard last_trigger updates in
ATTACK case.
bse_simple_adsr_update_modules(): run through the decay phase as usual,
even if attack time amounts to 0. calculate decay time attack-level
relative.

* icons/sub.c: save pixstream instead of pixdata parts.

* bseadder.c: construct icon from sub_pixstream instead of pixdata.

* bsenoise.c: use gsl_engine_block_size() instead of outdated
configuration option.

* artscompressor.cc:
* artscompressor.idl:
* bseadder.c:
* bseatandistort.c:
* bsefirfilter.c:
* bseiirfilter.c:
* bsemixer.c:

* bsesimpleadsr.c:
* davcanyondelay.c:
* davguitar.c:
* davorgan.c:
* davsyndrum.c:
* davxtalstrings.c: fixed channel naming, identifiers and i18n.

* artscompressor.idl bsebalance.idl davbassfilter.idl davchorus.idl:
Use "using namespace Bse" in the correct places.

* evaluator/bseevaluator.cc: Adapted source to the fact that
bse-plugin-generator now finally uses Sfi::String instead of a
gchar* representations.

* evaluator/compiler.cc: fix include.

* plugins/*.c: adapted to field order changes in BSE_REGISTER_OBJECT().

* evaluator/bseevaluator.idl: declare this plugin "unstable" through
type options.

* davbassfilter.idl:
* davbassfilter.cc: ported DavBassFilter.

* davbassfilter.[hc]: removed old DavBassFilter code.

* davsyndrum.c:
* davxtalstrings.c: fixed up trigger property flags.

* Makefile.am: removed old unused cruft. fixed up idl generation
rules, include idl files in dist tarballs.

bseevaluator.so (properly namespace prefixed).

* evaluator/bseevaluator.idl:
* artscompressor.idl:
* bsebalance.idl:
* davchorus.idl: stripped "/Module" prefix from categories as this
is auto-prepended by the idl compiler now and shouldn't be translated.
completed i18n markup of info strings, streams and parameter groups.

* davchorus.idl:
* bsebalance.idl:
* artscompressor.idl: started i18n markup.

* evaluator/bseevaluator.idl: changed category.

* evaluator/compiler.*: Support for parenthesis, and sin(x).
* evaluator/instruction.*: New Instruction::SIN instruction.
* evaluator/token.hh: Parenthesis.

* evaluator/*: Put implementation in the Bse::EvaluatorUtils
namespace.

* evaluator/evaluateexpr.cc: Error handling.

* Makefile.am: Added evaluator as subdirectory.

* evaluator/*: Added BseEvaluator, a module based on a small,
interpreted programming language which can compute expressions
like "output = input * 0.5 + 1".

* *.*: changed "copyright" field of procedures, scripts and objects
into a "license" field which better reflects what we're asking for.

* artscompressor.cc:
* artscompressor.idl: fix indentation and copyright notice.

* davxtalstrings.c: Fixed bug in triggering code inside inner loop.

* artscompressor.idl artscompressor.cc: Ported compressor from aRts.
Stereo compression is also supported, and works slightly differently
than in aRts because it uses only one volume for both channels, and
like this doesn't mess up balance.

* Makefile.am Makefile.plugins: Added compressor to the Makefiles.

* icons/balance.*: colorized icon.

* davsyndrum.c (dmod_process):

C plugin left that uses enum values.

* *.[hc]:
* freeverb/bsefreeverb.[hc]: ported all plugins to the new
export macros.

* icons/Makefile.icons:
* icons/*.png: added png files for the images used.

* icons/*.c: regenerated C sources from *.png files with:
gdk-pixbuf-csource --name=VariableName foo.png > foo.c

* davcanyondelay.[hc]: resurrected canyon-delay plugin,
adjusted user visible comments.

* davsyndrum.[hc]: resurrected David A. Bartold's SynDrum plugin.
optimized for speed, adjusted various settings and added more
input channels.

Real properties which are stored in floats 'cause they don't need
full double precision.

* bsecompressor.[hc]: get rid of this, it's a misnamed and badly
parameterized module.

* bseatandistort.[hc]: new module, offering the atan distortion
that could be achived with bsecompressor. this offers a saner linear
parameterization range and is a lot faster by using an equivalent
approximation of GSL.

* davxtalstrings.c (xmod_process): fix clipping bug i just introduced.

* davxtalstrings.c: some cleanups, provide sane trigger facility
via input signal and frequency input. finally provide an icon for
this plugin.

* freeverb/bsefreeverb.[hc] (free_verb_reconnect): reset
the freverb filter when the module got reconnected.

* bsesimpleresonancefilter.[hc]: disable this test module,
BSE's new biquad filter does things way better.

* *.c: fixes due to new GslClass layout.

* bsewaveosc.[hc]: move this into BSE as it's an fundamental
component and introduces procedures.

* bseadder.[hc]: implement input channels as jstreams.

* bsemixer.[hc]: slight cleanups.

* bsesnooper.[hc]: remove this module from plugins.

* *.c: category fixes.

* implemented BseFreeVerb module, a wrapper around the public domain

floats processing.
* bsenoise.[hc] bsegenosc.[hc] bsemixer.[hc] bsemult.[hc] bseadder.[hc]:
likewise.

* bseconstant.[hc]: constant value plugin.

* davchorus.[hc]: new chorus module from David A. Bartold
<foxx@mail.utexas.edu>.

* davguitar.c (dav_guitar_prepare): cut-off frequency fix from David,
let lesser DC pass through to avoid clipping.
