- 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.
