8931e524bf In sem_post, the field _has_waiters is no longer used, because some 
application destroys semaphore after sem_wait returns. Just enter
kernel to wake up sleeping threads, only update _has_waiters if
it is safe. While here, check if the value exceed SEM_VALUE_MAX and
return EOVERFLOW if this is true.

32ffd2336c Eliminate two cases of unwanted strncpy(). The name is not required 
by the current code, and the results would get overwritten anyway
by subsequent memset().

126b6df920 Make utmpx(3) thread safe if we support TLS. 
Because the utmpx interface is generally not required to be thread-safe,
but it is nice to have, if easy to do so. Therefore don't make a mess
out of the code and only use it if __NO_TLS is not defined.

cc583082f4 Use version 2 of semaphore provided by kernel umtx code, now if there is 
no waiters, we still increase and decrease count in user mode without
entering kernel, once there is a waiter, sem_post will enter kernel to
increase count and wake thread up, this is atomicy and allow us to
gracefully destroy semaphore after sem_wait returned.

012df2856c fts(3): Mention that FTS_NOCHDIR imposes {PATH_MAX} limits on the returned 
pathnames.

With the current API (no *at functions), FTS_NOCHDIR requires that the
fts_accpath start with the original path passed to fts_open(); therefore,
the depth that can be reached is limited by the {PATH_MAX} constraint on
this pathname.
