* external.cc (cygwin_internal): Add CW_CVT_MNT_OPTS to allow mount

Browse Source 
flag parsing.  Add CW_LST_MNT_OPTS case to allow mount flag listing.
	* mount.cc (fstab_read_flags): Rename from read_flags.  Make externally
	available.  Change input string to char ** to allow returning faulty
	option.  Add flag for avoiding debug output.
	(fstab_list_flags): New function to create list of options.
	* include/sys/cygwin.h (cygwin_getinfo_types): Add CW_CVT_MNT_OPTS and
	CW_LST_MNT_OPTS.
