the extended `sort` in features, ease of use, and performance.

It's often necessary to update the representation of a single
object in a table (e.g a struct, whose identity does not change
when its slots'
values are changed).  To do so, now the function may be called
like this:

  (vtable-update-object table object)

Instead of like this:

  (vtable-update-object table object object)

This also documents the behavior of the just-discovered limitation filed
as bug#69837.
* lisp/emacs-lisp/vtable.el (vtable-update-object): Make 'old-object'
argument optional.  (Bug#69666)

Remove redundant priority assignment.

* java/org/gnu/emacs/EmacsOpenActivity.java (onCreate): Handle

These changes came up while working on `cl-type-of` but are not
directly related to the new `cl-type-of`.
The BASE_PURESIZE bump was needed at some point on one of my
machine, not sure why.

* src/puresize.h (BASE_PURESIZE): Bump up.
* src/sqlite.c (bind_value): Don't use `Ftype_of`.
* lisp/emacs-lisp/seq.el (seq-remove-at-position): Simplify.
* lisp/emacs-lisp/cl-preloaded.el (finalizer):
New (previously missing) type.
* doc/lispref/objects.texi (Type Predicates): Minor tweaks.

* src/data.c (Fcl_type_of): New function, extracted from `Ftype_of`.
Make it return more precise types for symbols, integers, and subrs.
(Ftype_of): Use it.
(syms_of_data): Define the corresponding new symbols and defsubr
the new function.

* doc/lispref/objects.texi (Type Predicates): Document it.

* src/comp.c (emit_limple_insn): Use `Fcl_type_of`.

* lisp/emacs-lisp/cl-preloaded.el (subr): Demote it to `atom`.
(subr-native-elisp, subr-primitive): Add `compiled-function` as
parent instead.
(special-form): New type.

* lisp/obsolete/eieio-core.el (cl--generic-struct-tag):
* lisp/emacs-lisp/cl-generic.el (cl--generic-typeof-generalizer):
Use `cl-type-of`.
cl--generic--unreachable-types): Update accordingly.

test/src/data-tests.el (data-tests--cl-type-of): New test.
