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.
