It's unnecessary to lock the thread during creation. Simply extend
...
the scope of the active thread list lock.

Decouple the thread stack [de]allocating functions from the 'dead threads list'
...
lock. It's not really necessary and we don't need the added complexity
or potential for deadlocks.

Return gracefully, rather than aborting, when the maximum concurrent
...
threads per process has been reached. Return EAGAIN, as per spec.

Re-enable the garbage collector thread in anticipation of further
...
locking work. I can't see anything obviously wrong with it (other than
the need to update the locking).

Fix build breakage (on ia64) caused by a missing file descriptor to

- Pass a ucontext_t to _set_curthread. If non-NULL the new thread is set
...
as curthread in the new context, so that it will be set automatically when
the thread is switched to. This fixes a race where we'd run for a little
while with curthread unset in _thread_start.

- Define curthread as _get_curthread() and remove all direct calls to
...
_get_curthread(). This is similar to the kernel's curthread. Doing
this saves stack overhead and is more convenient to the programmer.
- Pass the pointer to the newly created thread to _thread_init().
- Remove _get_curthread_slow().

- Add libthr but don't hook it up to the regular build yet. This is an
...
adaptation of libc_r for the thr system call interface. This is beta
quality code.
