Subject: [PATCH] hash: factor, and guard against misbehaving hasher function
* lib/hash.c (safe_hasher): New function, to encapsulate the checking
of table->hasher's return value. Also protect against a hash value
so large that adding it to table->bucket would result in a NULL pointer.
(hash_lookup, hash_get_next, hash_find_entry): Use it in place of
open-coded check-and-abort.
