Windows: add pthread_sigmask() that does nothing

Browse Source 
A previous change introduced a call to pthread_sigmask() in order to block
SIGPIPE in a thread. Since there are no signal facilities on Windows that
are similar to POSIX signals, just ignore the request to block the signal.
In the particular case, the effect of blocking SIGPIPE on POSIX is that
write() calls return EPIPE when the reader closes the pipe. This is how
write() behaves on Windows.
