Log message:
	* 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.
	* fork.cc (frok::child): Accommodate wait_for_sigpipe parameter change.
	* fhandler.h (fhandler_*::write): Make ssize_t/__stdcall.
	(fhandler_*::write_overlapped): Ditto.
	(fhandler_*::raw_write): Ditto.
	(fhandler_*::readv): Ditto.
	(fhandler_*::writev): Ditto.
	(fhandler_*::raw_read): Make __stdcall.
	* fhandler: Accommodate changes to read/write functions throughout.
	* fhandler_clipboard.cc: Ditto.
	* fhandler_console.cc: Ditto.
	* fhandler_dsp.cc: Ditto.
	* fhandler_fifo.cc: Ditto.
	* fhandler_mailslot.cc: Ditto.
	* fhandler_mem.cc: Ditto.
	* fhandler_mem.cc: Ditto.
	* fhandler_random.cc: Ditto.
	* fhandler_tape.cc: Ditto.
	* fhandler_tty.cc: Ditto.
	* fhandler_virtual.cc: Ditto.
	* fhandler_windows.cc: Ditto.
	* fhandler_zero.cc: Ditto.
	* syscalls.cc (readv): Use ssize_t as temp variable.
	* fhandler.cc (fhandler_base::read): Coerce returned len to signed or it will
	never be treated as < 0.
	(fhandler_base::wait_overlapped): Minimize calls to GetLastError.  Remove
	duplicate debugging test.  Fix error return.
	* fhandler.h (fhandler_fifo::fifo_name): Declare new function.
	(fhandler_fifo::close): Ditto.
	(fhandler_fifo::dup): Ditto.
	(fhandler_fifo::close_on_exec): Ditto.
	* fhandler.cc (fhandler_fifo::fifo_name): Define new function.
	(FIFO_BUF_SIZE): New define.
	(cnp): Ditto.
	(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.
	(fhandler_fifo::close): Define.
	(fhandler_fifo::dup): Ditto.
	(fhandler_fifo::close_on_exec): Ditto.
