add pthread_atfork helpers to our threading shims
* libguile/null-threads.h:
* libguile/pthread-threads.h (SCM_DEFINE_ATFORK_HANDLERS_FOR_MUTEX)
(scm_i_pthread_atfork): Define a pthread_atfork shim, and a helper to
declare procedures to lock and unlock a mutex.
* libguile/threads.h (SCM_PTHREAD_ATFORK_LOCK_STATIC_MUTEX): New macro,
causes the snarfer to emit a pthread_atfork call to lock a mutex, if
threads are enabled.
