[PATCH] poll, select: handle ERROR_BROKEN_PIPE.

[Paolo Bonzini]

Hi Erik, this is what I'm applying.

* lib/poll.c (win32_compute_revents): Return POLLHUP when
PeekNamedPipe fails with ERROR_BROKEN_PIPE.
* lib/select.c (win32_compute_revents): Do not mark a pipe
as writeable if PeekNamedPipe fails with ERROR_BROKEN_PIPE.
