(bindat--unpack-group, bindat--length-group, bindat--pack-group):
Declare `last` and `tag` as dyn-scoped.

Also, in `funcall` macroexpand the function before checking to see if
we can remove the `funcall`.

* lisp/emacs-lisp/lisp-mode.el (lisp--el-match-keyword): Handle
special forms and macros the same way (bug#43265). This makes
things like (setq a '(if a b)) be fontified correctly (i.e., not
fontified as a keyword).

Rename and rewrite to return the inverse value. Non-inverted
predicate functions are easier to reason about.

Before this patch doing:
rm lisp/calendar/calendar.elc
make lisp/calendar/cal-hebrew.elc
would spew out lots of spurious such warnings about a `date` argument,
pointing to code which has no `date` argument in sight. This was
because that code had calls to inlinable functions (taking a `date`
argument) defined in `calendar.el`, and while `date` is a normal
lexical var at the site of those functions' definitions, it was
declared as dynbound at the call site.
* lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand):
Don't impose our local context onto the inlined function.
* test/lisp/emacs-lisp/bytecomp-tests.el: Add matching test.
* lisp/emacs-lisp/checkdoc.el (checkdoc-ispell-init): Always send
the Lisp words to the process (bug#6221). This allows an existing
ispell process to be correctly initialised.
This introduces two new optimizations. They're designed for code like
(while
(let (...)
(if ... (progn blabla t) (progn blabla nil)))
...)
and they allow the elimination of the test internal to `while` since
we can immediately know when we return `t` or `nil` what the result
of the test will be.
`cl-labels` tends to generate this kind of code when it applies the
tail-call optimization.
This moves two optimizations from the final pass to the main loop.
Both may enable further optimizations (and the second can be applied
repeatedly but "from the end", so the loop in the final pass only gets
to apply it once).
(pcase--split-pred, pcase--funcall): Adjust for `not`.
(pcase--get-macroexpander): New function.
(pcase--edebug-match-macro, pcase--make-docstring)
(pcase--macroexpand): Use it.

* lisp/emacs-lisp/lisp-mode.el (lisp-el-font-lock-keywords-2)
(lisp-cl-font-lock-keywords-2): Allow single-character symbol names.
* lisp/help-mode.el (help-xref-symbol-regexp): Also match symbol
names starting with symbol syntax (bug#6601, bug#24309).
* test/lisp/help-mode-tests.el (help-mode-tests-xref-button): Test
hyperlink creation for function names without symbol syntax.
* lisp/emacs-lisp/shortdoc.el (shortdoc--display-function): Use
describe-function as a fallback link when a function is not documented
in any Info manual. Also make the link respond to mouse-1, like the
rest of *Help* links, and add a proper help-echo property.
* lisp/help-fns.el (help-fns--mention-shortdoc-groups): Same link
improvement as described before, this time for the shortdoc groups
(bug#45750).
Implement a limited form of tail-call optimization for the special
case of recursive functions defined with `cl-labels`. Only self-recursion
is optimized, no attempt is made to handle more complex cases such a mutual
recursion.
The main benefit is to reduce the use of the stack, tho in my limited
tests, this can also improve performance (about half of the way to
a hand-written `while` loop).
(cl--self-tco): New function.
(cl-labels): Use it.
* lisp/subr.el (letrec): Optimize single-binding corner case.
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs--labels): Add tests
to check that TCO is working.
* lisp/emacs-lisp/eieio-core.el (eieio-defclass-autoload): Try to make
the wording of the warning about the obsoleted variable less confusing.
* lisp/emacs-lisp/bytecomp.el (byte-compile-check-variable): Don't
warn for lexical variables (Bug#39169). Fix spurious `or'.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp/warn-obsolete-variable-bound\.el): New test.
* test/lisp/emacs-lisp/bytecomp-resources/warn-obsolete-variable-bound.el:
New file.
`package-quickstart.el` files presume `package-activated-list`
is a bound variable, so make sure this is the case even when `package.el` is
not yet loaded.
