Re-add a few `set debug target' callbacks.

[Pedro Alves <pedro_alves at portugalmail dot pt>]

These methods are no longer inherited, but instead do the beneath
lookup themselves, so their corresponding debug_target callbacks are
now never reached.

Checked in.

2009-02-06  Pedro Alves  <pedro@codesourcery.com>

	* target.c (target_create_inferior, target_detach)
	(target_mourn_inferior, target_attach, target_close): Do target
	debug output.
	(debug_to_attach, debug_to_detach, debug_to_create_inferior)
	(debug_to_mourn_inferior, debug_to_close): Delete.
	(setup_target_debug): Adjust.
