Mac OS Classic specific fixes:core_8_4_2

	* generic/tclIOUtil.c (TclNewFSPathObj): on TCL_PLATFORM_MAC,
	skip potential directory separator at the beginning of addStrRep.
	* mac/tclMacChan.c (OpenFileChannel, CommonWatch): followup
	fixes to cut and splice implementation for file channels.
	* mac/tclMacFile.c (TclpUtime): pass native path to utime().
	* mac/tclMacFile.c (TclpObjLink): correctly implemented creation
	of alias files via new static proc CreateAliasFile().
	* mac/tclMacPort.h: define S_ISLNK macro to fix stat'ing of links.
	* mac/tclMacUtil.c (FSpLocationFromPathAlias): fix to enable
	stat'ing of broken links.
