rockbox/uisimulator/sdl/thread-sdl.c, branch master

- Move uisimulator/sdl/*.[ch] into the target tree, under firmware/target/hosted/sdl, uisdl.c is split up across button-sdl.c and system-sdl.c.

- 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.

Use API call instead of accessing a global variable for receiving the current thread.

threads_exit should be volatile being polled in a loop on a sim thread and be written by the GUI thread.

Allow sims to shut down normally from panic code.

Use cookies for thread identification instead of pointers directly which gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats. Everything gets incompatible so a full update is required.

Do core interrupt masking in a less general fashion and save some instructions to decrease size and speed things up a little bit. Small fix to a few places where interrupts would get enabled again where they shouldn't have been (context switching calls when disabled).

Add a complete priority inheritance implementation to the scheduler (all mutex ownership and queue_send calls are inheritable). Priorities are differential so that dispatch depends on the runnable range of priorities. Codec priority can therefore be raised in small steps (pcmbuf updated to enable). Simplify the kernel functions to ease implementation and use the same kernel.c for both sim and target (I'm tired of maintaining two ;_). 1) Not sure if a minor audio break at first buffering issue will exist on large-sector disks (the main mutex speed issue was genuinely resolved earlier). At this point it's best dealt with at the buffering level. It seems a larger filechunk could be used again. 2) Perhaps 64-bit sims will have some minor issues (finicky) but a backroll of the code of concern there is a 5-minute job. All kernel objects become incompatible so a full rebuild and update is needed.

Do some simplification in switch_thread regarding interrupt enabling which simplifies kernel objects as well. Simply doing unconditional disable/enable should be fine in the firmware. Not sure about the case in the bootloader for all targets and so will evaluate but that should be fine too if everything is masked.

Simplify the uisimulator I/O routine and let the rockbox thread calling the functions be the background thread. Should speed things up too and lose none of the advantanges of background I/O.
