MFC:

- signal handling
- thread suspension, add pthread_suspend/resume_all_np()

- don't allow the uthread kernel pipe to use the same descriptors as stdio
- make sigpending() and sigsuspend() account for signals that are pending on
the process as well as pending on the current thread
- thread_kern_poll(): limit maximum poll interval to 60 seconds
- _select(): return correct number of total bits set in all fd_set's,
change case of POLLNVAL as an error, remove POLLHUP and POLLERR from one case,
their place is most likely amongst read events
- use SA_RESTART for signal handlers
- disconnect uthread_sigblock.c and uthread_sigsetmask.c from the build,
remove sources not connected to build
- pthread_xxx and sem_xxx symbols are now weak
- remove #ifdef _THREAD_SAFE from sources -- it is not needed
