Hash table improvements

Implement hash_table_foreach macro, analogous to list_foreach.

Remove superfluous argument to hash_table_find_next().
(If the user needs to recheck the part of the list already
checked by hash_table_find(), they can just rerun that function.)

Add hash argument to hash_table_ops_t::key_equal.
The big change here is that users with big keys can store the hash
value alongside key in their entries, and for the low low cost of
sizeof(size_t) bytes eliminate a bunch of expensive key comparisons.

Also added a hash function for strings and arbitrary data.
Found this one by asking ChatGPT, because the latency of accesses
to my book collection is currently a couple of hours.

+ Some drive-by unused #include removal.
