Ubuntu defines _FORTIFY_SOURCE=2, which causes glibc longjmp() to check sp
when gcc optimization is enabled. The check does not allow longjmp() to be
used for switching threads and results in a "longjmp causes uninitialized
stack frame" error. This disables the check.

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.

* Remove THREAD_ID_CURRENT macro in favor of a thread_self() function, this allows thread functions to be simpler.
* thread_self_entry() shortcut for kernel.c.

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.

In switch_thread, make the call to profile_thread_stopped from an inline asm block to make sure the sp is pointing to the right place before storing the context. This apparently worked by luck with the old Gcc.
The workaround used for coldfire in the codeclib's __cyg_profile_func_enter does not work with newer gcc, however the workaround isn't needed for those so enable it only for coldfire gcc version < 4.

Also add a panicf() if buffer_alloc() doesn't have enough space left to allocate a requested buffer

General state is: Rockbox is usable (plays music, saves configuration, touchscreen works too).
Problems:
- Playing music in the background (i.e. when switching to another app) doesn't work reliably, but I'm working on that now.
- no cabbiev2 (only some preliminary files for it), no other default theme.
- screen flickers sometimes if the updates are too frequent
- no multi screen apk/package
- strange behavior when a phone call comes in
The java files (and the eclipse project) resides in android/, which is also supposed to be the build folder.
I've put a small README in there for instructions. There are some steps needed after the make part, which are described there,
and which eclipse mostly handles. But there ought to be some script/makefile rules which do that instead in the future.

This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

Lots of the changes are due to changing storage_(read|write)sectors() from macros to wrapper functions. This means that they have to be called with IF_MD2(drive,) again.

Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back.
Only implemented for PP and as3525 so far. More targets could be added, as well as more functions.
