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

Better than inserting ".word 0x51fc/b". Assembler doesn't support
them but does the plain "tpf" without extension words as well as
"trapf".

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.

- Add BUTTON_POWER.
- hm60x: Rename BUTTON_PLAY to more proper BUTTON_SELECT, which will make it
possible to unify hm60x and hm801 keymaps in some plugins.

Remove the implementations of all exceptions handlers from the
various crt0.S files and have a single implementation in system-arm.h
The new implementation is weak so that it can be overwritten by some
specific code (like the unwinder)

The scrolling code cannot differentiate between the BUTTON_TOUCHSCREEN post
from normal touches and the one posted in the timeout callback.
To fix introduce a global special button (BUTTON_REDRAW) that results
in the desired redraw. This existed already as a local kludge for android
and is now generalized.

The warnings 1207c7b was supposed to get rid of are sim-only. This
means the binsize argument used for the _FORTIFY_SOURCE fix did not
apply at all. This one actually checks the return values.

This patch implements HAVE_ADJUSTABLE_CPU_FREQ, it modifies the
following parameters when CPU is unboosted:
- s5l8702 voltage is decreased: 1.200V -> 1.050V
- CPU frequency is divided by 4: 216MHz -> 54MHz
- AHB frequency is divided by 2: 108MHz -> 54MHz

The existing ARCH Makefile variable is exported to the C code as well.
Additionally the version (arm-only for now) is detected as well. This
allows to for complete autodetection, i.e. that optimized ASM is picked up
if determined by preprocessor (CPU_ARM, etc).
Building a sim/raaa on a arm host will now automatically generate a arm
optmized build like we have for native targets.

For now it contains explicit SDRAM setup, cutting clock for unused
modules and turning off unused PLLs. This improves slightly mem
throughput as well as saves quite a bit of power.

* rename some java methods (to update(), initialize())
* re-create the ByteBuffer object from the framebuffer on every update.
This is needed now since 2c71aa9 added the possiblity for lcd_framebuffer to change.
* do so, along with the creation of the dirty Rect object, in native code.

Especially when unzipping rockbox.zip, the native code can be initialized
a lot later than the java code. The java code needs to be prevented from
accessing rockbox structures (e.g. current_tick, event queues) before they're
ready.
This commit adds wait_rockbox_ready() and fixes dodgy behavior of starting
rockbox via widget play button, headset remote buttons or multimedia keys.
Also fixes wrong small list items before first redraw.
