[PATCH] gdb: remove pre_init_ui_hook from top.c

[Simon Marchi]

This hook appears to be unused.  I guess it was used from insight or
something like that at some point.  But I grepped in today's source of
insight [1] and there was no match.  So I think it's safe to remove.

gdb/ChangeLog:

	* top.c (pre_init_ui_hook): Remove.
