The icoll code now has an IRQ storm detection mechanism which
will prevent the device from hard freezing in case it happen.

Simplified stack unwinder for ARM. This is port of
http://www.mcternan.me.uk/ArmStackUnwinding/
backtrace() is called from UIE() on native targets
and from panicf() on both native and ARM RaaA.

Now lcd_framebuffer is the only framebuffer in the system. We still use a ARM-buffered buffer
which serve as an intermediate buffer for copying, to accomodate the requirement of the controller.
We implement lcd_update_rect() properly using this new scheme (this requires two little quirks),
this allows to implement lcd_blit_yuv with the right semantic (bypasses the framebuffer). YUV to RGB
conversion is still done in software but the DCP CSC should be able to do that but the hardware rotation
scheme is not the same as our software so it will require some tricks.

Core, codecs and plugins link it separately so this gets rid of SOURCES trickery.
Don't build it for hosted targets.

move prototypes to ascodec.h
move code to ascodec*.c
YPR0: use adc-as3514.c instead of duplicating it
TODO: merge as3514.h and ascodec.h ?

* Introduce CONFIG_BATTERY_MEASURE define, to allow targets (application)
to break powermgmt.c's assumption about the ability to read battery voltage.
There's now additionally percentage (android) and remaining time measure
(maemo). No measure at all also works (sdl app). If voltage can't be measured,
then battery_level() is king and it'll be used for power_history and runtime
estimation.
* Implement target's API in the simulator, i.e. _battery_voltage(), so it
doesn't need to implement it's own powermgmt.c and other stubs. Now
the sim behaves much more like a native target, although it still
changes the simulated battery voltage quickly,
* Other changes include include renaming battery_adc_voltage() to
_battery_voltage(), for consistency with the new target functions and
making some of the apps code aware that voltage and runtime estimation
is not always available.

Voltage can be read using as3543 adc (i.e. ascodec api, on this target implemented
via ioctl()). TODO: Look into possibly controlling charging more by re-using
powermgmt-ascodec.c. However, charging seems to be controlled by the kernel,
so may not be needed.
Charger state can be read using /dev/minivet. It allows to differentiate between
wall charger and usb charging, but that's not implemented (is it even worthwhile?)

This port is a hybrid native/RaaA port. It runs on a embedded linux system,
but is the only application. It therefore can implement lots of stuff that
native targets also implement, while leveraging the underlying linux kernel.
The port is quite advanced. User interface, audio playback, plugins work
mostly fine. Missing is e.g. power mangement and USB (see SamsungYPR0 wiki page).
Included in utils/ypr0tools are scripts and programs required to generate
a patched firmware. The patched firmware has the rootfs modified to load
Rockbox. It includes a early/safe USB mode.
This port needs a new toolchain, one that includes glibc headers and libraries.
rockboxdev.sh can generate it, but e.g. codesourcey and distro packages may
also work.
Most of the initial effort is done by Lorenzo Miori and others (on ABI),
including reverse engineering and patching of the original firmware,
initial drivers, and more. Big thanks to you.

The new menu is very helpful on RaaA, but also shown in the sim. It shows
the process cpu usage, process' time stats (user,sys,real) and the cpu
frequency stats.
It uses a thread to sample the data, however the thread is not created
until the menu is visited for the first time.

Massage the way it interfaces a bit to make things more flexible.
The chroma_buf scheme on Sansa Connect and Creative ZVx calling the
lcd_write_yuv420_lines implementation in lcd-as-memframe.S with five params
with a chroma buffer that the function can't use wouldn't work anyway so just
have them use the stock implementation (really, how was that working?).

For this commit: Sansa e200v1, Gigabeat F, Gigabeat S and Mini2440 are
changed over. Quite a number of other targets probably can be as well.
General LCD code is moved out of the target drivers into
drivers/lcd-memframe.c.
