core: Add hashq_get_handle, hash, hash_ref, hash_set_x.

* src/mes.c (scm_symbol_hashq_table, scm_symbol_record_type,
scm_symbol_module, scm_symbol_buckets, scm_symbol_size): New symbols.
Update users.
* src/hash.c (hash_list_of_char): Rename from hashq_.  Respect size,
update callers.
(hashq_, hash_ hash, hashq_get_handle, hash_ref, hash_set_x_,
hash_set_x): New function.
(hashq_ref): Do not return handle.  Update callers.
