[PATCH] detaching and threaded linux apps

[Liam Stewart <liams@redhat.com>]

thread_db_detach and lin_lwp_detach don't remove their target operation
structures from the target list when a detach on a threaded application
is done. This leads to the failure of the num_lwps == 1 assertion if a
gdb user (for some reason) detaches again before starting/attaching to a
new inferior.

	* lin-lwp.c (lin_lwp_detach): Remove target operation structure
	from target stack after detach operations are done.
	* thread-db.c (thread_db_detach): Ditto.
