Ken Brown 0fda55133a Cygwin: FIFO: synchronize the fifo_reader and fifosel threads 
The fifo_reader thread function and the function select.cc:peek_fifo()
can both change the state of a fifo_client_handler.  These changes are
made under fifo_client_lock, so there is no race, but the changes can
still be incompatible.

Add code to make sure that only one of these functions can change the
state from its initial fc_listening state.  Whichever function does
this calls the fhandler_fifo::record_connection method, which is now
public so that peek_fifo can call it.

Slightly modify that method to make it suitable for being called by
peek_fifo.

Make a few other small changes to the fifo_reader thread function to
change how it deals with the STATUS_PIPE_CLOSING value that can
(rarely) be returned by NtFsControlFile.

Add commentary to fhandler_fifo.cc to explain fifo_client connect
states and where they can be changed.
