eliminate target_ops->deprecated_xfer_memory

As no target uses it anymore, it can finally go away.

After removing the deprecated_xfer_memory handling from
default_xfer_partial, we can delete the latter, because the only thing
it does is delegate to the target beneath unconditionally, which is
what the delegator installed by target-delegates.c will do for us if
no to_xfer_partial method is installed.

This was the last user of de_fault, so that goes away too.

Tested on x86_64 Fedora 17.

	* target.c (complete_target_initialization): Don't install
	default_xfer_partial as to_xfer_partial hook.
	(nomemory): Delete.
	(update_current_target): Don't INHERIT nor de_fault
	deprecated_xfer_memory.  Delete de_fault macro.
	(default_xfer_partial, deprecated_debug_xfer_memory): Delete.
	(setup_target_debug): Don't install a deprecated_xfer_memory hook.
	* target.h (struct target_ops) <deprecated_xfer_memory>: Delete
	field.
