The new opaque type replaces the previous use of vectors for obarrays. `obarray-make` now returns objects of this type. Functions that take obarrays continue to accept vectors for compatibility, now just using their first slot to store an actual obarray object. obarray-size and obarray-default-size now obsolete. * lisp/obarray.el (obarray-default-size, obarray-size): Declare obsolete. (obarray-make, obarrayp, obarray-clear): Remove from here. * src/fns.c (reduce_emacs_uint_to_hash_hash): Remove from here. * src/lisp.h (struct Lisp_Obarray, OBARRAYP, XOBARRAY, CHECK_OBARRAY) (make_lisp_obarray, obarray_size, check_obarray) (obarray_iter_t, make_obarray_iter, obarray_iter_at_end) (obarray_iter_step, obarray_iter_symbol, DOOBARRAY, knuth_hash): New. (reduce_emacs_uint_to_hash_hash): Moved here. * src/lread.c (check_obarray): Renamed and reworked as... (checked_obarray_slow): ...this. (intern_sym, Funintern, oblookup, map_obarray) (Finternal__obarray_buckets): Adapt to new type. (obarray_index, allocate_obarray, make_obarray, grow_obarray) (obarray_default_bits, Fobarray_make, Fobarrayp, Fobarray_clear): New. * etc/emacs_lldb.py (Lisp_Object): * lisp/emacs-lisp/cl-macs.el (`(,type . ,pred)): * lisp/emacs-lisp/cl-preloaded.el (cl--typeof-types): * lisp/emacs-lisp/comp-common.el (comp-known-type-specifiers): * lisp/emacs-lisp/comp.el (comp-known-predicates): * src/alloc.c (cleanup_vector, process_mark_stack): * src/data.c (Ftype_of, syms_of_data): * src/minibuf.c (Ftry_completion, Fall_completions, Ftest_completion): * src/pdumper.c (dump_obarray_buckets, dump_obarray, dump_vectorlike): * src/print.c (print_vectorlike_unreadable): * test/lisp/abbrev-tests.el (abbrev-make-abbrev-table-test): * test/lisp/obarray-tests.el (obarrayp-test) (obarrayp-unchecked-content-test, obarray-make-default-test) (obarray-make-with-size-test): Adapt to new type.
