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.

* 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().

thread_queue_wake() doesn't need the 2nd parameter. The original purpose
for it never came to be.
Non priority version mrsw_writer_wakeup_readers was left improperly
finished. Get that back into line.
