	* thread.h (struct thread): Add fields efalgs, user_handle and
	init.
	(thread_create_in): Rename from this...
	(thread_init): ... to this.  Remove the activity argument.
	Update all users.
	(thread_create): Remove declaration.
	(thread_destroy): Rename from this...
	(thread_deinit): ... to this.  Update all users.
	(thread_send_sp_ip): Remove declaration.
	(thread_exregs): New declaration.
	* thread.c: Include <hurd/thread.h>.
	(thread_lookup): Add additional asserts.
	(thread_create_in): Rename from this...
	(thread_init): ... to this.  Remove the activity argument.  Don't
	set THREAD->ACTIVITY.  Set THREAD->INIT to true.
	(thread_create): Remove function.
	(thread_destroy): Rename from this...
	(thread_deinit): ... to this.  Correctly calculate the bit to
	deallocate.  Fix assert.  Set THREAD->INIT to false.
	(thread_commission): If THREAD->INIT is false, first call
	thread_init.  Correctly calculate the thread ids to initialize.
	(thread_send_sp_ip): Remove function.
	(thread_exregs): New function.
	* rm.h (RPC_STUB_PREFIX): Include <hurd/thread.h>.
	(rm_method_id_string): Support RM_thread_exregs.
	(THREAD_ASPACE_SLOT, THREAD_ACTIVITY_SLOT): Move from...
	* ../hurd/thread.h: ... to this new file.
	* server.c: Include <hurd/thread.h>.
	(server_loop): Implement the thread_exregs RPC.
	* viengoos.c (system_task_load): Set THREAD->ACTIVITY to a
	capability designating ROOT_ACTIVITY.
