[PATCH 2/2] win32: make qemu_fd_register() specific to windows

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Move the declaration of the function to a windows-specific header.

The only user left now is SLIRP, which needs special treatement since
it doesn't provide event objects itself for the socket/fds.
