* tag 'win-socket-pull-request' of https://gitlab.com/marcandre.lureau/qemu: (25 commits)
  monitor: restrict command getfd to POSIX hosts
  qtest: enable vnc-display test on win32
  libqtest: make qtest_qmp_add_client work on win32
  qmp: add 'get-win32-socket'
  monitor: release the lock before calling close()
  qmp: 'add_client' actually expects sockets
  osdep: implement qemu_socketpair() for win32
  tests/docker: fix a win32 error due to portability
  char: do not double-close fd when failing to add client
  tests: fix path separator, use g_build_filename()
  win32: replace closesocket() with close() wrapper
  os-posix: remove useless ioctlsocket() define
  win32: avoid mixing SOCKET and file descriptor space
  slirp: open-code qemu_socket_(un)select()
  slirp: unregister the win32 SOCKET
  main-loop: remove qemu_fd_register(), win32/slirp/socket specific
  aio/win32: aio_set_fd_handler() only supports SOCKET
  aio: make aio_set_fd_poll() static to aio-posix.c
  win32/socket: introduce qemu_socket_unselect() helper
  win32/socket: introduce qemu_socket_select() helper
