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.

When scraping files from the repository allow passing an additional list of
files for which the timestamp of the last change is retrieved. Since this is
slow (the log needs to be traversed, since a blob doesn't know about commits
its referenced by) only specified files get this retrieved.

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.

Player-specific code remaining: usb_drv_(init,exit)
The iPods lack a MMU, so:
- physical, virtual, and uncached addresses are identical
- since we can't access uncached memory we discard caches when receiving data
Still not quite reliable on nano2g

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.

On big-endian architecture, DSP output must be coverted to little-
endian first. DSP output is also always interleaved stereo, 16 bit,
NATIVE_FREQUENCY and wavinfo should be correct for this.
Also, use standard clip_sample_16 already available.
