This dir is suitable for stuff that doesn't fit the target tree, e.g. because
it also builds on hosted or otherwise. It also has a generic subfolder for
fallback C implementations so that not all archs need to provide asm files.
SOURCES should only contain "foo.c" where foo.c includes the specific
<arch>/foo.c files from the subdirs using the preprocessor. This way automatic
selection of asm versions or generic C verion is possible.
For the start, the thread support files are moved, since ASM threads can
be used on hosted platforms as well. Since core_sleep() remains platform
specific it's moved to the corresponding system.h headers.

Make shutdown_hw() not return as it's supposed to, ensure sim_do_exit() is called from main thread and move sim_kernel_shutdown() into it to simplify things.

This replaces SDL threads with real cooperative threads, which are less cpu intensive and allow priority scheduling.
The backend for context switching is dependant on the host (sigaltstack/longjmp on Unix, Fibers on Windows).
configure has options to force or disallow SDL threads.

- remove infinite loop after exit()
- make sure picture_surface is initialized, and free it
- split gui_message_loop() in 3 functions and change prototype
- some code is only used in simulator

SDL docs say SDL_PumpEvent (implicitely called by SDL_Poll/WaitEvent)
may only be called from the thread that initializes the video subsystem,
apparently because Windows requires that.
So create an (or bring it back) SDL thread (with preemtive behavior) to read the
event queue for buttons and initialize the video subsystem.
I'd probably would have done that anyway because it enables an interrupt-like method to read them (no polling).

- 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.
