* gdbtk.tcl: Add ref counts to breakpoint tags.

	* Put quotes around function name in disassemble command to better
	handle assembler names containing `.'.
	* Make pclist element 0 be filler to avoid off-by-one problem with
	line numbers.
	* Set names of top-level windows.
	* Add register display window.
	* Add PC to label of assembly window.
