* nis/nis_call.c: Minor cleanups throughout.

	(rec_dirsearch) [HIGHER_NAME]: Correctly size ndomain array.
	(first_shoot): Add search_parent_first parameter.  Only if it is set
	search parent server first.
	If directory for table found through cold start cache is not the same
	as referenced in the cache, don't use it.
	(__nisfind_server): Take additional parameter.  Pass it on to
	first_shoot.
	(__prepare_niscall): Adjust __nisfind_server call.
	* nis/rpcsvc/nislib.h: Adjust __nisfind_server prototype.
	* nis/nis_table.c: Adjust __nisfind_server call.
	* nis/nis_lookup.c: Likewise.
	(nis_lookup): Don't loop endlessly if name is reduced to ".".
