(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.
