* fhandler.cc (fhandler::dup): Duplicate flags, too. 

* fhandler.h (fhandler_fifo::owner): Eliminate.
* fhandler_disk_file.cc (fhandler_base::fstat_fs): Handle on-disk devices
better.
(fhandler_base::fstat_helper): Ditto.
* fhandler_fifo.cc (fhandler_fifo::fhandler_fifo): Don't initialize obsolete
"owner".
(fhandler_fifo::open_not_mine): Add some debugging.  Duplicate correct handle
when we own it.
(fhandler_fifo::open): Set flags from input, not from first pipe.  Flag that
fork fixup is needed.
(fhandler_fifo::dup): Set errno correctly when DuplicateHandle fails.
* pinfo.cc (commune_send): Add debugging for fifo.
* cygwin/version.h: Bump API minor version to 127 to reflect exporting of
sigrelese.
