73bc900df9 2000-11-06 Fernando Nasser <fnasser@cygnus.com>
From  Steven Johnson  <sbjohnson@ozemail.com.au>:

        This set of changes add "hookpost-" as an expansion on the original
        hooking of commands to GDB. A Hook may now be run "AFTER" execution of
        a command as well as before.

        * command.h (struct cmd_list_element): Changed elements hook and hookee
        to hook_pre and hookee_pre respectively. Added hook_post and hookee_post
        for the post hook command operation. Added hook_in so that an executing
        hook can be flagged to prevent recursion.
        * command.c (add_cmd): Changed initilization of cmd_list_element to
        reflect above changes.
        (delete_cmd): Remove both pre and post hooks.
        (help_cmd): Notify that the command has pre and/or post hooks.
        * infrun.c (normal_stop): Change references to hook_pre from hook.
        * top.c (execute_command): Run both pre and post hooks.
        (define_command): Allow definition of both pre and post hooks.
        The definition of pre-hooks is done as before, with the "hook-"
        prefix for backward compatibility.

From David Whedon <dwhedon@gordian.com>

	* top.c (execute_command): Checks all commands beore executing
	to see if the user needs to be warned that the command is
	deprecated, warns user if appropriate.
	(add_info), (add_info_alias), (add_com) , (add_com_alias): Changed
	return values from void to struct cmd_list_element *.
	* command.c (lookup_cmd_1): Check aliases before following link
	in case user needs to be warned about a deprecated alias.
	(deprecate_cmd): new exported function for command deprecation,
	sets flags and posibly a replacement string.
	(deprecated_cmd_warning): New exported funciton to warn user about
	a deprecated command.
	(lookup_cmd_composition): New exported function that determines
	alias, prefix_command, and cmd based on a string.  This is useful
	is we want to full name of a command.
	* command.h : Added prototypes for deprecate_cmd,
	deprecated_warn_user and lookup_cmd_composition, added flags to
	the cmd_list_element structure, changed return values for
	add_com_* and add_info_* from void to cmd_list_element.
	* maint.c : (maintenance_deprecate): New function to deprecate a
	command.  This exists only so that the testsuite can deprecate
	commands at runtime and check the warning behavior.
	(maintenance_undeprecate) : New function, drops deprecated flags.

	Replace dual longjmp buffer memcpy with single pointer change.
	Add FIXME for possibly adding new interface to tell caller what
	event was caught.  Add extensive comments.
	* defs.h (enum return_reason): Reserve 0 for use as initial
