Abstracts threading from itself a bit, changes the way its queues are
handled and does type hiding for that as well.
Do alot here due to already required major brain surgery.
Threads may now be on a run queue and a wait queue simultaneously so
that the expired timer only has to wake the thread but not remove it
from the wait queue which simplifies the implicit wake handling.
List formats change for wait queues-- doubly-linked, not circular.
Timeout queue is now singly-linked. The run queue is still circular
as before.
Adds a better thread slot allocator that may keep the slot marked as
used regardless of the thread state. Assists in dumping special tasks
that switch_thread was tasked to perform (blocking tasks).
Deletes alot of code yet surprisingly, gets larger than expected.
Well, I'm not not minding that for the time being-- omlettes and break
a few eggs and all that.

find_first_set_bit() becomes a small inline on ARMv5+ and checkwps now gets
made with -std=gnu99 (it eats all the GCCOPTS) like the rest of things.

When the align parameter was a 32bit value (like all default integer literals),
and the to-be-aligned value is a pointer the upper 32bit got corrupted because
the value was casted down to 32bit.
Note: This hasnt been a problem because apparently the sim always gets 32bit
addresses (I found this when compiling Rockbox as a library).

No code changed, just shuffling stuff around. This should make it easier to
build only select parts kernel and use different implementations.

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.

This fixes errornous pointer addition (+ on a short*), which crashed in some situation.
Fixes FS#12317 and should hopefully get the clips booting again.
Thanks to Jonathan Gordon for spotting the bad pointer arithmetic.

buffer chunks.
* Samples and position indication is closely associated with audio data
instead of compensating by a latency constant. Alleviates problems with
using the elapsed as a track indicator where it could be off by several
steps.
* Timing is accurate throughout track even if resampling for pitch shift,
whereas before it updated during transition latency at the normal 1:1 rate.
* Simpler PCM buffer with a constant chunk size, no linked lists.
In converting crossfade, a minor change was made to not change the WPS until
the fade-in of the incoming track, whereas before it would change upon the
start of the fade-out of the outgoing track possibly having the WPS change
with far too much lead time.
Codec changes are to set elapsed times *before* writing next PCM frame because
time and position data last set are saved in the next committed PCM chunk.

The NDK includes swap16 and swap32 macros, Rockbox as well. Use the Rockbox
ones and avoid a macro redefined warning.

The old cache coherency function names where wrong and misleading.
The new names are (purposely different from vendor manuals)
* commit_* (write-back only)
* discard_* (removing lines from cache only)
* commit_discard_* (write-back and removing lines from cache)
It's suspected the old names have led to wrong uses. The old names still exist
(as aliases) so every call via the old names need to be double checked and changed
to the new name.

- Move ATTRIBUTE_PRINTF/ATTRIBUTE_SCANF from _ansi.h
They are not related at all to this file, and this broke compilation
with Code Sourcery GCC which ships its own _ansi.h
- Move LIKELY/UNLIKELY from system.h
There is likely a lot more GCC extensions used everywhere in the source,
conditionally on __GNUC__ or unconditionally

ideally all targets should define CACHEALIGN_BITS, for now we default it
to 16 bytes if it's not specified
Since the buffer is already aligned in playback.c no need to align it
again in buffering.c

The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR).
The new define is to (de-)select code to compile on hosted platforms generally.
Should be no functional change to targets or the simulator.

- Refactor the program startup. main() is now in main.c like on target, and the implicit application thread will now act as our main thread (previously a separate one was created for this in thread initialization).
This is part of Rockbox as an application and is the first step to make an application port from the uisimulator. In a further step the sim bits from the sdl build will be separated out.
