Implementation, documentation and naive regression tests for:
- pthread_spin_init()
- pthread_spin_destroy()
- pthread_spin_lock()
- pthread_spin_trylock()
- pthread_spin_unlock()
Implementation okay guenther@, documentation okay jmc@.

Implementation and documentation for:
- pthread_barrier_init()
- pthread_barrier_destroy()
- pthread_barrier_wait()
- pthread_barrierattr_init()
- pthread_barrierattr_destroy()
- pthread_barrierattr_getpshared()
- pthread_barrierattr_setpshared()
Currently only private barriers are supported.

that it resumes waiting unless the thread was canceled. As part
of this, change the internal _sem_wait() function to return zero
on success and an errno value on failure instead of 1 on success
and zero on failure.

don't try to merge values, round the sizes separately, and don't try to
unmap application-supplied stacks.
Copy from uthread the caching of default-sized stacks.
Have pthread_attr_init() and pthread_create() get the default attributes
from staticly allocated pthread_attr_t.
Cache the pagesize in _rthread_init() and provide a macro for rounding to it
based on suggestions from kettenis@ and tedu@, ok kettenis@

particularly the "consume the signal you just sent" hang, and putting
the wait queues in userspace.
Do cancellation handling in pthread_cond_*wait(), pthread_join(),
and sem_wait().
Add __ prefix to thr{sleep,wakeup,exit,sigdivert}() syscalls; add
'abort" argument to thrsleep to close cancellation race; make
thr{sleep,wakeup} return errno values via *retval to avoid touching
userspace errno.

kernel so that librthread can detect when a thread is completely
done with its stack without need a kqueue. The dying thread moves
itself to a GC list, other threads scan the GC list on pthread_create()
and pthread_join() and free the stack and handle once the thread's
thread id is zeroed.

signal is already pending in the calling thread or the main thread
and there's no longer a race condition where the signal could be
diverted but sigwait() would still block. There were some off-by-one
errors too.
(The checking of the main thread's pending list is just until a
pending list for the process can be added to struct process. For
now, such signals end up as pending on the main thread.)

- Make an effort to protect important libc and ld.so critical areas during
the fork(2)/vfork(2) sys call.
- Add pthread_atfork(3) implementation based on Daniel Eischen's code.
Original diff by Philip Guenther <guenther at gmail.com> with some
additions and refinements by me. Positive test report from brad@ with
many kde apps. fork(2) and pthread_atfork(3) pthread regresses pass.

where output is to stderr and will only be printed if the current
debug level is >= 3. Messages with a debug level of 0 are always
printed. The level can be set from the environment (not enabled yet)
or with gdb by modifying variable _rthread_debug_level.

With this, java seems to be operational. Also make threads_ready
non-static, which is needed for an upcoming diff. ok tedu@
