* pthread.h (SIG_BLOCK): Define if not already defined.
(SIG_UNBLOCK): Likewise.
(SIG_SETMASK): Likewise.
(pthread_attr_t): Add signal mask member.
(pthread_sigmask): Add function prototype.
* signal.c (pthread_sigmask): Implement.
* create.c: #include <string.h> to get a prototype for memcpy().
(pthread_create): New threads inherit their creator's signal
mask. Copy the signal mask to the new thread structure.
