Corinna Vinschen 7aa88267c1 * fhandler.h (fhandler_base::status): Declare private. 
(fhandler_base::open_status): Ditto.
	(class fhandler_socket): Move status bits into private bitfield struct
	type status_flags.  Change accessor methods appropriately.
	* fhandler_socket.cc (fhandler_socket::fhandler_socket): Accomodate
	above status bit changes.
	* tty.h: Remove status bit enumerator.
	(TTYISSETF): Remove.
	(TTYSETF): Remove.
	(TTYCLEARF): Remove.
	(TTYCONDSETF): Remove.
	(tty_min::status): Define as private bitfield struct type status_flags.
	Add appropriate accessor methods.
	* fhandler_console.cc: Use tty_min::status accessor methods throughout.
	* fhandler_termios.cc: Ditto.
	* winsup.h (__ISSETF): Remove.
	(__SETF): Remove.

PATH_MAX is from Posix and does *not* include the trailing NUL.
MAXPATHLEN is from Unix.
Thou shalt use CYG_MAX_PATH throughout. It avoids the NUL vs no-NUL
issue and is neither of the Unixy ones [so we can punt on which
one is the right one to use].
Windows ANSI calls are limited to MAX_PATH in length. Cygwin calls that
thunk through to Windows Wide calls are limited to 32K. We define
CYG_MAX_PATH as a convenient, not to short, not too long 'happy medium'.
