	* main.tcl (gdbtk_preloop): Call gdbtk_idle on spec.  If there was an
        error in loading an executible specified on the command line,
	then the pre_add_symbol hook would have called gdbtk_busy but
        the corresponding call to gdbtk_idle would not have occured.

        Also changed some catch calls so they didn't use
        "catch {set foo [real_command]}"
	    but rather the more efficient:
	"catch {real_command} foo"

	* register.tcl: more catch cleanups
	* src.tcl: more catch cleanups
	* stack.tcl: more catch cleanups
	* target.tcl: more catch cleanups
	* tdump.tcl: more catch cleanups
	* variables.tcl: more catch cleanups
	* watch.tcl: more catch cleanups

	* gdbtk.c (gdbtk_init): Fixed a bug in the startup code on Windows
	that caused gdbtk not to find the share directory unless
	GDBTK_LIBRARY was set.

	* gdbtk.c: removed all the commands and hooks from this file so
	now it contains only the startup code.
 	* gdbtk_cmds.c: New file - this contains all the Tcl commands that
	gdb defines.  All the old commands were moved here, the
	string-based commands were converted to object commands, and the
	object-based commands were all converted to uniformly use the
	call_wrapper.  A new function, Gdbtk_Init was added to centralize
	initializing the gdb package.  Also added gdbtk as a package
	into gdbtk_interp.
	* gdbtk_hooks.c: New file - All the hooks were moved here, and a new
	function, gdbtk_add_hooks was added to centralize adding all these
	hook functions.  gdbtk_fputs was also modified to handle the new
	result_ptr structure.  See the comments in gdbtk.h for more
	details.
	* gdbtk.h: New file - this contains all the defines and globals
	shared by gdbtk.c, gdbtk_cmds.c & gdbtk_hooks.c
	* Makefile.in, configure.in & configure: mutatis mutandi for the
	new files.
