Migrate MH-E functional tests from SourceForge

* test/lisp/mh-e/mh-limit-tests.el:
* test/lisp/mh-e/mh-utils-tests.el:
* test/lisp/mh-e/mh-xface-tests.el:
Import the functional tests from src/mh-unit.el.

mh-unit.el is from the old SourceForge mh-e repository, last changed
in 2017.  To this are applied unmerged patches Mike Kupfer wrote in
2018 ("Refactor mh-unit into functional and release tests" and
"Fix the functional tests").

All tests have been converted to run under Emacs's ERT framework.

Some tests for mh-utils use MH programs to examine mail folders.
These tests require an MH variant to be installed on the system; for
these, added both a mock harness that pretends the needed files and MH
programs do exist, and a wrapper that creates the necessary mail files.

New function 'mh-test-utils-setup-with-variant' bears some resemblance
to 'mh-test-folders-set-up' from the original tests.  New function
'mh-test-utils-setup-with-mocks' is new functionality for these tests.

Rename from 'project-remove-known-project', for consistency with
'project-remember-project' (discussed in bug#50297).

Consistently test alist keys with equal in map.el

* etc/NEWS: Announce new default behavior of map-elt and map-delete
on alists.

* lisp/emacs-lisp/map.el: Bump to version 3.2.
(map-elt): Test alist keys with equal by default.  Betray a little
bit more information in the docstring on which functions are used
for which map types.  (Bug#47368)
(map-put): Update docstring accordingly.
(map--plist-delete): Consistently test plist keys with eq.
(map-delete): Consistently test alist keys with equal.

for new map-elt behavior.
(test-map-put!-alist, test-map-delete-alist): New tests.

Remove the emoji script overrides for U+2xxx codepoints

* admin/unidata/blocks.awk: Remove the overrides for U+261D, U+26F9,
U+270C..U+270D, and U+2764.  They don't belong in the emoji script.

Fix the UK flag sequence composition regexp

* admin/unidata/emoji-zwj.awk: Fix the regexp for UK flags.
Thanks to Mattias Engdegård <mattiase@acm.org> and his magic
regexp checker.

Silence byte-compiler warning for network-stream-tests.el

The api specifically requires a symbol here, so we can't just replace
nowait with nil.

* test/lisp/net/network-stream-tests.el
(open-gnutls-stream-old-api-wait): Add explicit value for nowait
to silence byte-compiler warning due to Bug#47080.

Avoid double argument evaluation in vc-call macro

* lisp/vc/vc-hooks.el (vc-call): Ensure second argument is evaluated
only once (bug#50690).
* etc/NEWS (Change Logs and VC): Announce this change in behavior.

Make syntax-ppss more accurate for Python triple quotes (bug#49518)

By putting delimiter syntax on the last character of Python
triple-quoted strings, this makes syntax-ppss be more accurate.

Previously:

    emacs -Q something.py
    type two single quotes
    M-: (nth 3 (syntax-ppss))
    notice how the return value says you're outside a string, correctly
    type another quote
    M-: (nth 3 (syntax-ppss))
    notice how the return value says you're inside a string, correctly
    backspace the quote just entered
    M-: (nth 3 (syntax-ppss))
    notice how the return value says you're inside a string, incorrectly

With this patch the last step is corrected.  This helps things like
electric-pair-mode.  Also, the test
python-syntax-after-python-backspace now passes, again.

* lisp/progmodes/python.el (python-syntax-stringify): Put
delimiter syntax in "inner" of the surrouding triple quotes.

* test/lisp/progmodes/python-tests.el
(python-syntax-after-python-backspace): Passes again.

Expand and improve electric-pair-mode and Python testing (bug#49518)

In python-tests.el, the triple-quote pairing tests are passing
incorrectly, i.e. the auto-pairing functionality they purport to guard
isn't really working for users trying it interactively.  Added a new
failing test, soon to be fixed.

In electric-tests.el, added tests for Python, too.

* test/lisp/electric-tests.el (define-electric-pair-test): Also run
main tests for python-mode.  (pair-some-quotes-skip-others): Test
another slightly different pairing.

* test/lisp/progmodes/python-tests.el
(python-triple-double-quote-pairing): Rename from
python-triple-quote-pairing.
(python-triple-single-quote-pairing): New test.

Add docstring for 'electric-pair-p-s-i-f' and minor refactor

Extract the "open newline between pairs behaviour" into its own
function, electric-pair-open-newline-between-pairs-psif.

* lisp/elec-pair.el (electric-pair-post-self-insert-function): Add
docstring.
(electric-pair-open-newline-between-pairs-psif): New function.
(electric-pair-mode): Add/remove electric-pair-open-newline-between-pairs-psif

Speed up test/lisp/electric-tests.el when run interactively

'blink-paren-function' and its timers could sometimes interfere with
the tests and slow them down significantly.

* test/lisp/electric-tests.el (call-with-saved-electric-modes):
Bind blink-paren-function to nil.

; Minor checkdoc fixes in url/*.el

Fix whitespace-report window creation

* lisp/whitespace.el (whitespace-display-window): Avoid creating
many buffers if called many times (bug#50716).

Use `special-mode' for whitespace-report

* lisp/whitespace.el (whitespace-report-region): Use
`special-mode' instead of `fundamental-mode' (bug#50715).

Inhibit warning in mm-inline-wash-with-file from previous change

* lisp/gnus/mm-view.el (mm-inline-wash-with-file): Inhibit warning
about previous lexical fixup.

Fix problems with non-ASCII non-encoded PGP names

* lisp/epg.el (epg-signature-to-string): User IDs may be
non-encoded, non-ASCII (bug#50706).

Fix typo in tex--prettify-symbols-alist

* lisp/textmodes/tex-mode.el (tex--prettify-symbols-alist): Fix
varsigma typo (bug#50710).

Fix lexical fallout in mm-inline-wash-with-file

* lisp/gnus/mm-view.el (mm-inline-wash-with-file): This is only
called from the `links' handler, and it passes in `file' expecting
that to be dynamically bound.  Which is a very, very confusing
interface, but make that work again, anyway.

Make dired-compress-file query for a directory to uncompress to

* lisp/dired-aux.el (dired-compress-file-suffixes): Specify the
directory in the tar targets.
(dired-uncompress-file): New function (bug#47058).  This asks what
directory to uncompress to.
(dired-compress-file): Use it.

Clear netrc cache in auth-source test

* test/lisp/auth-source-tests.el
(auth-source-test-netrc-create-secret): Clear the netrc cache, too.

Only search netrc in the netrc tests

* test/lisp/auth-source-tests.el
(auth-source-test-netrc-create-secret): Only search netrc.

Remove some last calls to Gnus group name encoding

This should have been part of cb12a84f2c

* lisp/gnus/gnus-msg.el (gnus-summary-resend-message-insert-gcc,
gnus-inews-do-gcc): Don't encode group names.

; Mention it in NEWS too

New command: project-find-dir

* doc/emacs/maintaining.texi (Project File Commands):
Mention the new command and update the bindings information.

* lisp/progmodes/project.el (project-find-dir):
New command (bug#43153).
(project-prefix-map): Use 'd' as its binding.
Move 'project-dired' to 'D'.
(project-switch-commands):
Replace 'project-dired' with 'project-find-dir'.

those without. Bug#39799, I hope.

* .gitignore: Add emoji-zwj.el
* admin/notes/unicode: Add emoji-zwj-sequences.txt and
emoji-sequences.txt references.  Describe how to test after updating
to a newer Unicode version.

* admin/unidata/emoji-sequences.txt: New file.
* admin/unidata/emoji-zwj-sequences.txt: New file.
* admin/unidata/emoji-zwj.awk: New file.  Derives
composition-function-table rules from emoji-zwj-sequences.txt, plus
hardcodes some derived manually from emoji-sequences.txt.
* etc/NEWS: Announce change.
* lisp/international/characters.el: Load the generated emoji-zwj.el
