Fix bug #18420 with deadlocks communicating with subprocess on MS-Windows.
src/w32.c (fcntl): Support O_NONBLOCK fcntl on the write side of
pipes.
(sys_write): When a write to a non-blocking pipe returns ENOSPC,
set errno to EAGAIN instead, to allow the caller to retry the
write after some waiting. Fixes deadlocks when Emacs exchanges a
lot of data through the pipe.
