* Makefile.in (OBSOLETE_FUNCTIONS): Add fcntl.

Browse Source 
(NEW_FUNCTIONS): Add fcntl64.
	* cygwin.din: Export fcntl64.  Make fcntl being SIGFE.
	* fcntl.cc (fcntl_worker): New function.
	(fcntl64): New function.
	(_fcntl): Call fcntl_worker.  Convert 32 bit flock structure into
	64 bit flock structure and vice versa.
	* fhandler.cc (fhandler_base::lock): Change 2nd parameter to
	struct __flock64 *.
	* fhandler_disk_file.cc (fhandler_disk_file::lock): Ditto.  Rework
	to be 64 bit aware.
	* fhandler.h: Accomodate above method argument changes.
	* include/cygwin/types.h: Add struct __flock32 and __flock64.
	Define struct flock according to setting of __CYGWIN_USE_BIG_TYPES__.
	* include/cygwin/version.h: Bump API minor number.
