pflocal: support SO_SNDBUF for unconnected sockets
We can store the requested value, to be applied when we connect the
sockets.
* pflocal/sock.h (struct sock): Add req_write_limit field.
* pflocal/sock.c (sock_create): Initialize req_write_limit field to 0.
(sock_connect): Bump the write_limit of the write pipe to the
req_write_limit value.
(sock_shutdown): Update req_write_limit from the write_limit of the
write pipe.
* pflocal/socket.c (S_socket_getopt, S_socket_setopt): When write_pipe
is NULL, use req_write_limit.
