Log message:
Reimplement mutexes, condvars, and rwlocks to eliminate bugs,
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.
