        Note: The original patch used asprintf/vasprintf.  I changed it to
	use the new xasprintf/xvasprintf gdb functions.
        * gdbtk.c (TclDebug, gdbtk_init): Replaced the vast majority of
	sprintf/vsprintf calls with asprintf and vasprintf respectively.
	Should prevent any possible buffer overruns possible with
	fixed size sprintf buffers. Specifically fixes a problem with long
	filenames and clearing breakpoints overflowing their buffers when
	using sprintf, causing a segfault. Generically should also prevent
	any other similar problems from occuring.
        * gdbtk-cmds.c (sprintf_append_element_to_obj, get_pc_register,
	gdb_get_tracepoint_info, gdb_load_disassembly, gdbtk_load_source,
	gdbtk_load_asm, gdb_set_bp, gdb_set_bp_addr, gdb_get_breakpoint_info,
	gdb_selected_frame, gdb_selected_block, gdb_get_blocks): Ditto.
        * gdbtk-hooks.c (gdbtk_warning, gdbtk_ignorable_warning,
	gdbtk_readline_begin, gdbtk_set_hook, breakpoint_notify,
	gdbtk_query, tracepoint_notify, gdbtk_error_begin,
	gdbtk_annotate_signal): Ditto.
