*	overhaul sem_open	Rich Felker	2012-09-30	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \|	this function was overly complicated and not even obviously correct. avoid using openat/linkat just like in shm_open, and instead expand pathname using code shared with shm_open. remove bogus (and dangerous, with priorities) use of spinlocks. this commit also heavily streamlines the code and ensures there are no failure cases that can happen after a new semaphore has been created in the filesystem, since that case is unreportable.
*	clean up, bugfixes, and general improvement for shm_open/shm_unlink	Rich Felker	2012-09-30	1	-9/+28
\| \| \| \| \| \| \|	1. don't make non-cloexec file descriptors 2. cancellation safety (cleanup handlers were missing, now unneeded) 3. share name validation/mapping code between open/unlink functions 4. avoid wasteful/slow syscalls
*	implement POSIX shared memory	Rich Felker	2011-03-03	1	-0/+21
