* generic/tcl.decls :

	* generic/tclMain.c :
	* unix/tclAppInit.c:
	* win/tclAppInit.c: Added two new internal functions,
	TclSetStartupScriptFileName() and TclGetStartupScriptFileName()
	and added hooks into the main() code for supporting TclPro and
	other "big" shells more easily without requiring a copy of the
	main() code.

	* generic/tclEncoding.c:
	* generic/tclEvent.c:  Moved encoding-related startup code from
	tclEvent.c into the more appropriate tclEncoding.c.
