Log message:
Validate timespec and return ECANCELED when interrupted with SA_RESTART.
Discussing with mpi@ and guenther@, we decided to first fix the existing
semaphore implementation with regards to SA_RESTART and POSIX compliant
returns in the case where we deal with restartable signals.
Currently we return EINTR everywhere which is mostly incorrect as the
user can not know if she needs to recall the syscall or not. Return
ECANCELED to signal that SA_RESTART was set and EINTR otherwise.
Regression tests pass and so does the posixsuite. Timespec validation
bits are needed to pass the later.
OK mpi@, guenther@
