relate: optimize with hashes.
* lib.c (do_relate_hash, do_relate_hash_dfl): New static
functions.
(relate): If the number of keys and values is the same, and
there are more than ten, then use hashing.
If the default value is specified, and it is nil, then a hash
table can be returned directly, instead of a function.
* txr.1: Note added that relate may return a hash.
