5f7a108732 Avoid passing along a timespec with a negative number of seconds if 
the current time plus the caller-supplied time to sleep wraps the
time_t. Instead, sleep until INT_MAX.

22f226cf84 Correct the order of arguments to __sigplusset() in two places to correct

916de87872 Keep the kernel updated with signal action signal masks (act.sa_mask) until

method will be used. Fixes regress/lib/libpthread/sigmask2.

1eaf7124f7 Fetch the old signal mask for the signal action whether or not we're 
setting a new signal action; this makes sigaction(sig, NULL, &oact)
return a sensible value in the signal mask instead of stack trash.

Addresses PR lib/29536.

XXX the mask seen by signal handlers in a program linked with
libpthread but not yet multithreaded will not reflect masks set here.

efffd0e96a pthread_rwlock_timedrdlock() and pthread_rwlock_timedwrlock():

077972bfb2 Replace the even-odd test for incrementing unblockgen with a simple 
blockgen!=unblockgen.  I'm not sure this is 100% correct, but it partly
alleviates a problem with multiple unblocks for the same thread getting
stacked up.

74718675cc Avoid passing zero-valued timespecs to timer_settime() when we want to set 
a timer, as that will clear the timer instead. Pass in a safely in-the-past
value instead.
Addresses PR lib/28700.

(XXX passing in values between 0 and 1000 nanoseconds will still fail, but
 that bug needs to be fixed in timer_settime(), not here)

fae5965c52 Implement pthread_attr_{set,get}schedpolicy() at the same level as the other 
scheduling stuff: only handle SCHED_OTHER. Like the rest of the scheduling
stuff, this is for the benefit of code that can't be bothered to test against
_POSIX_THREAD_PRIORITY_SCHEDULING.

480a2816f2 Add #defines to make use of libc stubs for pthread_cond_wait() and 
pthread_cond_timedwait().

XXX as noted in the comments, in the situations where these are
useful, they should never be called in a single-threaded
process. Perhaps they should die rather than return 0.

0eaa8971b7 Use CPP macros to cause many libpthread functions used by applications 
to be transformed into the do-nothing-when-libpthread-isn't-linked libc
stub names. This will permit library code that uses <pthread.h> and pthread
functions "defensively" to not need to link against libpthread and not need
to be patched to the threadlib.h API.

45204d9ceb Punt to setcontext() system call if the PSL_T bit (single-step trap) 
is set, so that the single-step trap happens in the thread's context
and not in the middle of _setcontext_u.

XXX might be able to do something here with iret, too, but it needs
more testing.
