Add MSG_PEEK support to pflocal
* libpipe/pq.h (packet_peek): Declare new function.
* libpipe/pq.c (packet_read): Move code to new `packet_fetch' function, call it
with `remove' set to 1.
(packet_fetch): New function with code from `packet_read', but do not remove
data if `remove' is 0.
(packet_peek): New function, calls `packet_fetch' with `remove' set to 0.
* libpipe/dgram.c (dgram_read): When MSG_PEEK is in *flags, do not dequeue
and only peek data.
* libpipe/seqpack.c (seqpack_read): Likewise.
* libpipe/stream.c (stream_read): Likewise.
* pflocal/socket.c (S_socket_recv): Pass MSG_PEEK flag to libpipe.
