	* proc.h (struct ids): Drop gids and ngids, we never use
	them.  Turn uids into a zero length array.
	* mgt.c (make_ids): Conform to new semantics.
	(ids_free): Removed.  Rendered obsolete by ids_rele.
	(ids_rele): New function.  Drop a reference to the given
	ids.
	(ids_ref): Add a reference to the given ids.
	(S_proc_reauthenticate): Use ids_rele and new make_ids
	semantics.
	(S_proc_child): Use ids_rele and ids_ref.
	(create_startup_proc): Conform to new make_ids semantics.
	(complete_proc): Use ids_ref.
	(process_has_exited): Use ids_rele.
	* host.c: Doc fix: ``Implement foo as described in <hurd/proc.defs>''
	=> ``Implement foo as described in <hurd/process.defs>''
	* info.c: Likewise.
	* mgt.c: Likewise.
	* pgrp.c: Likewise.
	* wait.c: Likewise.
	* mgt.c (S_proc_reauthenticate): Calculate the value of
	NGEN_UIDS, NAUX_UIDS, NGEN_GIDS AND NAUX_GIDS; do not use
	a constant.
	(create_startup_proc): Add asserts.
	* host.c (S_proc_setexecdata):  Check for memory allocation errors.
	Use memcpy, not bcopy.
	(S_proc_getexecdata): Likewise.
	(S_proc_execdata_notify): Check return of malloc.
	(S_proc_register_version): Likewise.
	(initialize_version_info): Add asserts.
	* info.c (S_proc_pid2task): Do not bother searching for the pid
	if we do not have a valid caller.
	(S_proc_pid2proc): Likewise.
	Use memcpy, not bcopy.
	(S_proc_getprocinfo): Doc fixes.  Use MAP_FAILED not -1.  Use
	memcpy, not bcopy.
	(S_proc_getloginpids): Check return value of malloc.  Use realloc
	correctly.
	(S_proc_setlogin): Check return value of malloc.
	* main.c (main): Assert allocate_proc.
	* mgt.c (make_ids): Check return value of malloc and fail
	accordingly.
	(S_proc_reauthenticate): Check return value of make_ids and fail
	accordingly.
	(S_proc_child): Call task_find after we know that we were passed
	a valid child.
	(S_proc_reassign): Likewise.
	(S_proc_handle_exceptions): Use memcpy, not bcopy.
	(allocate_proc): Check return value of ports_create_port and fail
	accordingly.
	(create_startup_proc): Add asserts.
	(complete_proc): Do not assume the length of "<none>".
	* msg.c (S_proc_getmsgport): Call pid_find_allow_zombie after
	we know we were passed a valid caller.
	* pgrp.c: Include assert.h.
	(new_pgrp): Check return value of malloc and fail accordingly.
	(new_session): Likewise.
	(boot_setsid): Assert sess.
	(S_proc_getsessionpids): Use MAP_FAILED not -1.
	(S_proc_getsessionppids): Likewise.
	(S_proc_getpgrppids): Likewise.
	* wait.c (S_proc_wait): Use memset, not bzero.
