Christopher Faylor 43c23d4b82 * sigproc.h (wait_for_sigthread): Eliminate parameter.
* sigproc.cc (wait_for_sigthread): Ditto.  Don't synchronize with wait_sig
after receiving an event that it is ready to go.
(init_sig_pipe): New function.
(wait_sig): Call init_sig_pipe to create pipes for communicating signals to
this process.  Don't send sigCONT signal when initializing.

(fhandler_fifo::open): Rework.  Use cnp to open named pipe.  Always open write
side as a client.  Open dummy client when writing and can't connect.
(wait): Rework.  Implement fifo_wait_for_next_client.  Handle signals during
connect better.  Add new fifo_wait_for_server code which polls
(sigh) waiting for server.
(fhandler_fifo::raw_read): Handle transition states when one client closes and
another is available.
