Don't hard-code "~/.emacs.d/" in two more places

locate-user-emacs-file.  (Bug#47880)

; * test/lisp/progmodes/xref-tests.el: Add footer.

Factor out a helper macro to create a temporary directory.

This is a useful abstraction, and saves a few levels of indentation in
the test body.

* test/lisp/progmodes/project-tests.el
(project-tests--with-temporary-directory): New helper macro.

filenames before passing them to 'xref-matches-in-files'.

Verify that 'project-current' returns the right project.

Skip a unit test that requires an external program if necessary.

* test/lisp/progmodes/project-tests.el (project/quoted-directory):
Skip if the 'find' program isn't available.  The 'project-files'
function uses 'find' to obtain the list of project files.

Update modus-themes to version 1.3.2

* doc/misc/modus-themes.org (COPYING): Reword to match the phrasing of

This file is needed for CEDET's bootstrap, tho, so we now keep a copy of it

the `ldefs-boot.el` copy of `loaddefs.el`.

`lisp/cedet/semantic/grammar-wy.el`.

(define-minor-mode): Warn about use of pre-Emacs-21 style args

* lisp/emacs-lisp/easy-mmode.el (define-minor-mode):
Use `advertised-calling-convention` to avoid promoting the old

on a region that's longer than the file (bug#47718).

Copyright-paperwork-exempt: yes

* lib-src/seccomp-filter.c: Add missing headers.

Generate Seccomp filters only if we have the necessary constants.

If we're missing SECCOMP_SET_MODE_FILTER, the seccomp-filter build
fails.  Reuse the existing HAVE_SECCOMP configuration variable, which
checks for these macros.

* configure.ac (HAVE_SECCOMP): Substitute in Makefile.in.
* lib-src/Makefile.in (HAVE_SECCOMP): New variable.
(SECCOMP_FILTER): Define only if HAVE_SECCOMP.

Back in Emacs-21.1, `define-minor-mode` grew keywords arguments to

the old-style any more.

Also prefer #' to quote functions.

(message-send-rename-function, message-reply-to-function)
(message-wide-reply-to-function, message-followup-to-function):
Use a non-nil default value so it can be used with `add-function`.
(message-do-send-housekeeping): Tweak accordingly.
(message-get-reply-headers): Simplify by η-reduction.

Also remove redundant `:group` args

* lisp/progmodes/bug-reference.el: Avoid old-style `define-minor-mode`

(bug-reference-mode, bug-reference-prog-mode): Remove redundant args.

* src/emacs.c (load_seccomp): Consistently check for nonzero result

Add a variant of the Seccomp filter file that allows 'execve'.

This is useful when starting Emacs with a Seccomp filter enabled,
e.g. using 'bwrap'.

* lib-src/seccomp-filter.c (main): Generate new Seccomp files.

* lib-src/Makefile.in (all)
(seccomp-filter.bpf seccomp-filter.pfc seccomp-filter-exec.bpf
seccomp-filter-exec.pfc): Generate new Seccomp files.

* .gitignore: Ignore new Seccomp files.

* test/src/emacs-tests.el (emacs-tests/bwrap/allows-stdout): New unit
test.

* lib-src/seccomp-filter.c (main): Also allow O_NOFOLLOW.

Don't attempt to generate Seccomp filter file in Linux < 4.14.

Only Linux 4.14 and later contain the required support for
SECCOMP_RET_KILL_PROCESS.

* lib-src/Makefile.in (SECCOMP_FILTER): Define only if we run at least
Linux 4.14.

Seccomp filter: allow reading the current time (Bug#47708).

* lib-src/seccomp-filter.c (main): Allow reading the current time.

Fix check for timer_getoverrun

* configure.ac (timer_getoverrun): Move check after gnulib checks
and use $LIB_TIMER_TIME during check.

Use pkg-config to check for libseccomp.

We need at list version 2.4.0 of libseccomp for seccomp-filter.c to
build cleanly.

* configure.ac: Use pkg-config to check for libseccomp.
* lib-src/Makefile.in (HAVE_LIBSECCOMP, LIBSECCOMP_LIBS)
(LIBSECCOMP_CFLAGS): New variables.
(SECCOMP_FILTER, seccomp-filter$(EXEEXT)): Use them.

Remove SCMP_FLTATR_CTL_LOG attribute from Seccomp filter.

Whether or not we log failing syscalls isn't security-critical, and we
shouldn't care.

* lib-src/seccomp-filter.c (main): Remove log attribute.

Only attempt to generate seccomp filter files on x86-64 systems.

The seccomp filters are always architecture-specific, and
seccomp-filter.c right now only supports x86-64.

* lib-src/Makefile.in (SECCOMP_FILTER): New variable.
(DONT_INSTALL, all, seccomp-filter$(EXEEXT)): Use it.

; * etc/NEWS: Minor copyedits.

* lib-src/seccomp-filter.c: Print trailing newline.

* doc/lispref/elisp.texi (Top): Add missing entry.

Fix calculator-string-to-number yet again (bug#47694)

* lisp/calculator.el (calculator-string-to-number):
The last bugfix changed the code to just blindly replace ".e".  This
has some minor problems like making "-." parse as 0.0 instead of -0.0,
and ".1.e1" is parsed as 1 instead of 0.1.  Instead, replace the first
"." that is followed by a non-digit with ".0".  Since this has had
several problems over the years, add some tests too.  (Also, restore
the original if-indentation style.)

Fix typo in cconv

* lisp/emacs-lisp/cconv.el (cconv-convert): Typo.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test case.

Add another check for the required header <linux/filter.h>.

* configure.ac: Also check for <linux/filter.h>.
* src/emacs.c (SECCOMP_USABLE): Also check for <linux/filter.h>.

Also check for needed seccomp macros.

It looks like these are not available on some versions of GNU/Linux,
breaking the build.

* configure.ac: Also check for needed seccomp macros.
* src/emacs.c (SECCOMP_USABLE): New macro.
(usage_message, main, standard_args): Use it.
