* main.c (main): Remove calls to {pre,post}_add_symbol_hooks.
There should be sufficient information/hooks now to eliminate
this hack.
* exec.c (file_command): Add a new hook here to inform ui's
when the exec file has changed. Adding it here allows the
ui to be informed after symbol reading.
* gdbcore.h: Add declaration of file_changed_hook.
