+ 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 results in a NULL pointer.
+ (hash_lookup, hash_get_next, hash_find_entry, transfer_entries):
+ Use it in place of open-coded check-and-abort.
