hash: change make_hash interface.

The make_hash function now takes the hash_weak_opt_t
enumeration instead of a pair of flags.

* hash.c (do_make_hash): Take enum argument instead of pair of
flags. Just store the option; nothing to calculate.
(weak_opt_from_flags): New static function.
(tweak_hash): Function removed.
(make_seeded_hash): Adjust to new do_make_hash interface with
help from weak_opt_from_flags.
(make_hash, make_eq_hash): Take enum argument instead of pair
of flags.
(hashv): Calculate hash_weak_opt_t enum from the extracted
flags, pass down to make_eq_hash or make_hash.

* hash.h (tweak_hash): Declration removed.
(make_hash, make_eq_hash): Declarations updated.

* eval.c (me_case, expand_switch): Update make_hash
calls to new style.
(eval_init): Update make_hash calls and get rid of tweak_hash
calls. This renders the tweak_hash function unused.

* ffi.c (make_ffi_type_enum, ffi_init): Update make_hash calls
to new style.

* filter.c (make_trie, trie_add, filter_init): Likewise.

* lib.c (make_package_common, obj_init, obj_print): Likewise.

* lisplib.c (lisplib_init): Likewise.

* match.c (dir_tables_init): Likewise.

* parser.c (parser_circ_def, repl, parse_init): Likewise.

* parser.l (parser_l_init): Likewise.

* struct.c (struct_init, get_slot_syms): Likewise.

* sysif.c (get_env_hash): Likewise.

* lex.yy.c.shipped, y.tab.c.shipped: Updated.
