* lisp/emacs-lisp/cconv.el: Improve line-nb info of unused var warnings

Instead of warning about unused vars during the analysis phase of
closure conversion, do it in the actual closure conversion by
annotating the code with "unused" warnings, so that the warnings
get emitted later by the bytecomp phase, like all other warnings,
at which point the line-number info is a bit less imprecise.

Take advantage of this change to wrap the expressions of unused
let-bound vars inside (ignore ...) so the byte-compiler can better
optimize them away.

Finally, promote `macroexp--warn-and-return` to "official" status
by removing its "--" marker.

but instead remember the fact in `cconv-var-classification`.

Remove variable.

(\`):
* lisp/emacs-lisp/cl-macs.el (cl--do-arglist): Use `car-safe` instead
of `car`, so it can more easily be removed by the optimizer if the
result is not used.

* lisp/progmodes/dcl-mode.el: Minor doc fixes.

Remove check for missing easymenu from cperl-mode.el

Fix pcase rx pattern bugs

Two unrelated bugs: A missing type check caused an error in rx
patterns for non-string match targets, and rx patterns did not work at
all in pcase-let or pcase-let*.

Second bug reported by Basil Contovounesios and Ag Ibragimov; fixes
proposed by Stefan Monnier.  Discussion and explanation in thread at
https://lists.gnu.org/archive/html/emacs-devel/2021-02/msg01924.html

* lisp/emacs-lisp/rx.el (rx): Add (pred stringp) to avoid type errors,
and replace the `pred` clause for the actual match with something that
works with pcase-let(*) without being optimised away.

Don't crash if gnutls_handshake fails

In some situations involving Internet access not being fully
functional, gnutls_handshake returns a fatal error, which we were
ignoring, causing us to call gnutls_handshake again.  Now we check for
the error and return it to the caller.

* src/gnutls.c (gnutls_try_handshake): Return immediately if
gnutls_handshake returns a fatal error (Bug#46709).

`edebug-form-spec`.

* test/lisp/emacs-lisp/macroexp-tests.el (macroexp--tests-file-name): Add case

Add use of `macroexp-file-name` from a macro called from within
a function, which works thanks to eager-macroexpansion (so the macro
is expanded which the file is being loaded rather than only later
when the function is called).

* test/lisp/emacs-lisp/macroexp-resources/m1.el
(macroexp--m1-tests-file-name): New function.

* test/lisp/emacs-lisp/macroexp-tests.el (macroexp--tests-file-name): New test

* lisp/emacs-lisp/macroexp.el (macroexp-file-name): Work in `eval-buffer`

Rely on `current-load-list` instead of `load-file-name`.

Change the var we override accordingly.

(tab-prefix-map): Bind "O" to 'tab-previous'.

* lisp/emacs-lisp/macroexp.el (macroexp-file-name): New function.

Yes, finally: a function that tells you the name of the file where
the code is located.  Finding this name is non-trivial in practice,
as evidenced by the "4 shift/reduce conflicts" warning when compiling
CEDET's python.el, because its `wisent-source` got it wrong in that
case, thinking the grammar came from `python.el` instead of
`python-wy.el`.

While at it, also made `macroexp-compiling-p` public, since it's
useful at various places.

(macroexp-compiling-p): Rename from `macroexp--compiling-p`.

* lisp/emacs-lisp/bytecomp.el (byte-compile-close-variables):
Bind `load-file-name` to nil so we can distinguish a load that calls
the byte compiler from a byte compilation which causes a load.

* lisp/cedet/semantic/wisent/python.el (wisent-python--expected-conflicts):
Remove; it was just a workaround.
* lisp/subr.el (do-after-load-evaluation): Avoid `byte-compile--` vars.
* lisp/cedet/semantic/fw.el (semantic-alias-obsolete):
Use `macroexp-compiling-p` and `macroexp-file-name`.
* lisp/cedet/semantic/wisent/comp.el (wisent-source): Use `macroexp-file-name`
(wisent-total-conflicts): Tighten regexp.
* lisp/emacs-lisp/cl-lib.el (cl--compiling-file): Delete function
and variable.  Use `macroexp-compiling-p` instead.
* lisp/progmodes/flymake.el (flymake-log):
* lisp/emacs-lisp/package.el (package-get-version):
* lisp/emacs-lisp/ert-x.el (ert-resource-directory):
Use `macroexp-file-name`.

  (newsticker--treeview-item-show): Show feed name from
  newsticker-url-list if wanted.
  (newsticker--treeview-propertize-tag): Add argument 'tooltip'.
  (newsticker--treeview-tree-get-tag): Usefeed name from
  newsticker-url-list if wanted.  (Fixes third issue in
  Bug#41376.)

Fix wisent/python.el grammar warning

* lisp/cedet/semantic/wisent/python.el: Fix warning about
shift/reduce conflicts in the Python grammar.

Fix warning generated by indian.el + quail.el

* lisp/leim/quail/indian.el (quail-define-indian-trans-package):
Reintroduce kludge to fix automatic detection by Quail.
