	gdb            : ChangeLog thread-db.c lin-lwp.c 

Log message:
	Implement attach/detach for multi-threaded programs on Linux.
	* thread-db.c (keep_thread_db): Adjust comment.
	(deactivate_target): Removed.
	(thread_db_new_objfile): Don't call deactivate_target.  Implement
	guts of deactivate_target inline instead.
	(attach_thread): Call ATTACH_LWP unconditionally if defined.
	(thread_db_attach): New function.
	(thread_db_detach): Don't call deactivate_target.  Do necessary
	cleanup inline instead.  Set inferior_ptid to LWP corresponding to
	the current user-level thread.
	(thread_db_kill): Set inferior_ptid to LWP corresponding to the
	current user-level thread.
	(thread_db_create_inferior): Deactivate target vector if
	KEEP_THREAD_DB is zero.
	(thread_db_mourn_inferior): Don't call deactivate_target.  Do
	necessary cleanup inline instead.
	(init_thread_db_ops): Initialize to_attach field to
	thread_db_attach.
	* lin-lwp.c (lin_lwp_mourn_inferior): Remove prototype.
	(stop_wait_callback): Add prototype.
	(init_lwp_list): Add comment about when to re-initialize the LWP
	list.
	(lin_lwp_attach_lwp): Only call ptrace for cloned processes.
	Avoid adding publicates to the LWP list.  Only mark an LWP as
	signalled if it doesn't correspond to a cloned process.
	(lin_lwp_attach): Add initial process to the LWP list.  Make sure
	it's stopped and fake a SIGSTOP.
	(detach_callback): New function.
	(lin_lwp_detach): Implement.
	(lin_lwp_create_inferior): Don't re-initialize LWP list here.
	Call child_ops.to_create_inferior directly instead of via
	target_beneath local.
	(lin_lwp_mourn_inferior): Call child_ops.to_mourn_inferior
	directly instead of via target_beneath local.
