normal 889f50227c socket: expand docs+tests for recv_io/send_io
* ext/socket/unixsocket.c (unix_send_io): document args
  (unix_recv_io): ditto
* test/socket/test_unix.rb (test_fd_passing_class_mode): added

I was working on these when I encountered the problem in
with BasicSocket.for_fd not handling mode args:
