88aeef9127 Remove pointless IRAM allocation from voice DSP.
It's always used in MONO mode and doesn't need the IRAM sample/
resample buffers and 1280 bytes can be freed.

M5 can now have its PCM mixer downmix buffer in IRAM.

dbe5e5f2df rbcodec: Hooks for target specific functions in dsp_process loop
Use them to move tick counting, yielding and coldfire macsr handling
code to a rockbox specific file.

f5d9a45e3f Should've had dsp_replaygain_set_gains as static for now...
...because currently gains are only set through dsp_configure.

57a20d2d63 Make DSP's replaygain independent of global_settings.
Moves replaygain definitions to lib/rbcodec/dsp/dsp_misc.h.
Intermediate functions in misc.c handle any adjustment and calling
the rbcodec APIs.

Hmmm, how'd I miss that?

230f6f4326 Lower IRAM footprint on ARM.
Move a few functions to .text that probably don't see a huge benefit
from being .icode. Will scrutinize later.

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.

need to access global_settings.

e5c3327cef Add a more correct absolute difference function to dsp-util.
Differences between signed samples cover the entire unsigned 32-bit
range. "abs" will think any difference exceeding INT32_MAX is negative
which is not corrent. Test which argument is greater and subtract the
lesser from it, outputting unsigned difference.
