tool-bar-map has a buffer local value or not as that made the
documentation complicated. Documentation added in Emacs manual,
Elisp manual, package commentary, and docstrings. Also extend

Change `function` so that when evaluating #'(lambda ...)
we return an object of type `interpreted-function` rather than
a list starting with one of `lambda` or `closure`.
The new type reuses the existing PVEC_CLOSURE (nee PVEC_COMPILED)
tag and tries to align the corresponding elements:
- the arglist, the docstring, and the interactive-form go in the
same slots as for byte-code functions.
- the body of the function goes in the slot used for the bytecode string.
- the lexical context goes in the slot used for the constants of
bytecoded functions.
The first point above means that `help-function-arglist`,
`documentation`, and `interactive-form`s don't need to
distinguish interpreted and bytecode functions any more.
Main benefits of the change:
- We can now reliably distinguish a list from a function value.
- `cl-defmethod` can dispatch on `interactive-function` and `closure`.
Dispatch on `function` also works now for interpreted functions but still
won't work for functions represented as lists or as symbols, of course.
- Function values are now self-evaluating. That was alrready the case
when byte-compiled, but not when interpreted since
(eval '(closure ...)) signals a void-function error.
That also avoids false-positive warnings about "don't quote your lambdas"
when doing things like `(mapcar ',func ...)`.

The obsolete lazy-loaded bytecode feature, enabled by
`byte-compile-dynamic`, slows down Lisp execution even when not in use
because every call to a bytecode function has to check that function
for laziness.
This change forces up-front loading of all lazy bytecode so that we
can remove all those checks. (Dynamically loaded doc strings are not
affected.)
There is no point in generating lazy bytecode any more so we stop
doing that; this simplifies the compiler. `byte-compile-dynamic` now
has no effect.
This is a fully compatible change; the few remaining users of
`byte-compile-dynamic` should not notice any difference.

"Language grammar" is apparently the more widely used term among
people talking about tree-sitter. To avoid confusion, I think it's
good to use that rather than "language definition", which is a term

Thorough redesign of the Bindat system, which makes it possible
to define new Bindat type forms, define recursive types, control
the values returned when unpacking, freely mix arbitrary computations

This also reverts the recent addition of the `bindat-spec` macro and
the support for 64bit integers in the old Bindat language since that
is now considered obsolete anyway.

This redoes the 2019-11-02T00:24:02!eggert@cs.ucla.edu patch,
updated after consultation with John Sullivan.
Omit printed edition numbers in online manuals while keeping
them in printed manuals. In online manuals the edition
numbers seem to cause more confusion than they cure; e.g.,
https://shop.fsf.org/books/gnu-emacs-manual-18th-edition-v-261
currently advertises "18th edition" even as it points to
https://www.gnu.org/software/emacs/manual/pdf/emacs.pdf which
says "Seventeenth Edition". It is simpler and less confusing
to stick to one version number like "27.0" in online manuals.
For printed manuals people can run, e.g., "texi2any -D
'EDITION Nineteenth'" when generating the 19th printed edition
of the Emacs manual.
* doc/emacs/emacs.texi (EDITION):
* doc/lispintro/emacs-lisp-intro.texi (edition-number, update-date):
* doc/lispref/elisp.texi (VERSION, DATE):
Remove definitions. Instead, let the person printing the book
specify these values, with the default being the online version
which does not have printed edition numbers.
* doc/lispintro/emacs-lisp-intro.texi (titlepage-edition-number):
New flag, for the edition number as it appears on the title page.
