fbe33e0728 Fix libmad compilation on MIPS with newer gcc. FS#12013
Since gcc 4.4 the MIPS port no longer recognizes the "h" asm constraint.
It was necessary to remove this constraint in order to avoid generating
unpredictable code sequences. We can achieve the same effect using
128-bit types.

dd61978070 Expand the range of the inverse quant table in WMA Pro.
Several of the problem samples on the tracker use values outside this
range.  Trying the larger table doesn't quite seem to fix things, but
its only a small amount of additional memory and looking at ffmpeg,
I think the larger table is correct.

f8d54460f2 support decoding of files that contain the number of vector coded coefficients in their bitstream
No known samples are fixed by this problem, but I haven't tested many.

Backport of ffmpeg revision 26388.

It was only needed by the old arm toolchain that we no longer use or support.

cadb3627fc Add rbcodecplatform.h and rbcodecconfig.h.
librbcodec users must provide these two files when the library is built.
rbcodecconfig.h provides configuration #defines and basic types, and
will be included by public librbcodec headers, so it must not conflict
with the user's code. rbcodecplatform.h provides various OS functions,
and will only be included by source files and private headers. This
system is intended to provide maximum flexibility for use on embedded
systems, where no operating system headers are included. Unix systems
can just copy rbcodecconfig-example.h and rbcodecplatform-unix.h with
minimal changes.

for real this time.  Also, use English grammar.

87d3dde15a Fix corrupt when repeatidly playing very low bitrate WMA files.
The LSP feature in WMA requires that the noise table values be
doubled verses when it is not used.  Unfortunately, the previous
code would double the same values every time a LSP file was
decoded without first resetting them to their original values.
Change the code to check if the values are already doubled, and
then double/halve them as needed.  This is still a bit ugly,
in the future consider using the built in rockbox dither instead
of a lookup table.

Fixes playback when skipping back and forth between low and high
bitrate WMA.

c9bcbe202d Fundamentally rewrite much of the audio DSP.
Creates a standard buffer passing, local data passing and messaging
system for processing stages. Stages can be moved to their own source
files to reduce clutter and ease assimilation of new ones. dsp.c
becomes dsp_core.c which supports an engine and framework for effects.

Formats and change notifications are passed along with the buffer so
that they arrive at the correct time at each stage in the chain
regardless of the internal delays of a particular one.

Removes restrictions on the number of samples that can be processed at
a time and it pays attention to destination buffer size restrictions
without having to limit input count, which also allows pcmbuf to
remain fuller and safely set its own buffer limits as it sees fit.
There is no longer a need to query input/output counts given a certain
number of input samples; just give it the sizes of the source and
destination buffers.

Works in harmony with stages that are not deterministic in terms of
sample input/output ratio (like both resamplers but most notably
the timestretch). As a result it fixes quirks with timestretch hanging
up with certain settings and it now operates properly throughout its
full settings range.
