6ffb8ffeee Do a better endian.h setup that isn't as fragile
We redefine the top-level macros to our own in order to maintain
compatibility with compound initializers by wrapping the mid or low
level definitions from the OS header.

This allows, hopefully optimized, macros from the host OS's headers to
be used when building any hosted target obviating the need for
NEED_GENERIC_BYTESWAPS unless the target simply doesn't define its
own optimized versions (MIPS!).

Throw in some 64-bit swaps for completeness' sake; they generate no code
if not yet used anyway.

6ed00870ab Base scheduler queues off linked lists and do cleanup/consolidation
Abstracts threading from itself a bit, changes the way its queues are
handled and does type hiding for that as well.

Do alot here due to already required major brain surgery.

Threads may now be on a run queue and a wait queue simultaneously so
that the expired timer only has to wake the thread but not remove it
from the wait queue which simplifies the implicit wake handling.

List formats change for wait queues-- doubly-linked, not circular.
Timeout queue is now singly-linked. The run queue is still circular
as before.

Adds a better thread slot allocator that may keep the slot marked as
used regardless of the thread state. Assists in dumping special tasks
that switch_thread was tasked to perform (blocking tasks).

Deletes alot of code yet surprisingly, gets larger than expected.
Well, I'm not not minding that for the time being-- omlettes and break
a few eggs and all that.

981d028c09 Do some kernel cleanup
* Seal away private thread and kernel definitions and declarations
into the internal headers in order to better hide internal structure.

* Add a thread-common.c file that keeps shared functions together.
List functions aren't messed with since that's about to be changed to
different ones.

* It is necessary to modify some ARM/PP stuff since GCC was complaining
about constant pool distance and I would rather not force dump it. Just
bl the cache calls in the startup and exit code and let it use veneers
if it must.

* Clean up redundant #includes in relevant areas and reorganize them.

* Expunge useless and dangerous stuff like remove_thread().

355b5406fa Make errno a thread-local variable.
errno is supposed to be thread local and we do that here in a rather
makeshift way by implementing a function that returns a pointer to
the __errno variable in the thread block.

If more serious TLS is required, perhaps it would be worthwhile
implementing it using the linker and the "__thread" storage attribute.
That's a bit overkill just for this. I'm also not liking what I saw
the compiler producing.

2c2e261648 Use system headers a bit more: use host's fcntl.h for O_RDONLY etc.
Removes the need to fix up those in the simulator.

Also work around some posix-mingw incompatibilities (e.g. getcwd()).

a72aa856bd Move some gcc extensions to new gcc_extensions.h header
- Move ATTRIBUTE_PRINTF/ATTRIBUTE_SCANF from _ansi.h
  They are not related at all to this file, and this broke compilation
  with Code Sourcery GCC which ships its own _ansi.h
- Move LIKELY/UNLIKELY from system.h

There is likely a lot more GCC extensions used everywhere in the source,
conditionally on __GNUC__ or unconditionally

Skipped the specifiers for octal, (u)int_leastN_t, (u)int_fastN_t and
(u)intmax_t as we don't use them in rockbox

Specifiers use the types specified in stdint.h
Specifiers for short (16 bits) and char (8 bits) use the int specifier,
our format.c doesn't know about 'h' and 'hh'

3d0cee8abb - 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.

50a6ca39ad Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes).
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.
