(Bug#70939)

* configure.ac (C_SWITCH_MATCHINE): On 32-bit x86 with GCC 4+,

documentation.

* etc/NEWS: Announce this change.

This has a few benefits.  First, it fixes a race condition when killing
old processes in 'eshell-command'.  Second, the "wait" built-in command
is now more useful.  Finally, killing processes when exiting Eshell (via
'eshell-round-robin-kill') should be much faster.

* lisp/eshell/esh-proc.el (esh-opt): Require.
(eshell-wait-for-process): Make obsolete in favor of...
(eshell-wait-for-processes): ... this.  Accept a timeout and support
PIDs.  Update callers.
(eshell/wait): New implementation accepting -t/--timeout.
(eshell-round-robin-kill): Use 'eshell-wait-for-processes'.

* lisp/eshell/eshell.el (eshell-command): Use 'eshell-round-robin-kill'.

* doc/misc/eshell.texi (List of Built-ins): Document the new "wait"
behavior.

* etc/NEWS: Announce this change.

When invoking D-Bus methods, let the user enable interactive
authorization by passing an :authorizable t parameter.  This makes
it possible to D-Bus methods that require polkit authorization.

* configure.ac (HAVE_DBUS_MESSAGE_SET_ALLOW_INTERACTIVE_AUTHORIZATION):
Set a new variable if `dbus_message_set_allow_interactive_authorization'
is available.

* src/dbusbind.c (dbus-message-internal): Allow interactive
authorization by passing :authorizable t.

* doc/misc/dbus.texi (Synchronous Methods, Asynchronous Methods):
* etc/NEWS:
* lisp/net/dbus.el (dbus-call-method-asynchronously): Document the
new parameter.

This user option leads to a very large amount of false positives in
practice.  In my personal experience, almost all occurrences that are
flagged are false positives.  Flipping the default to something less
intrusive should hopefully encourage more use of checkdoc.

* lisp/emacs-lisp/checkdoc.el
(checkdoc-verb-check-experimental-flag): Switch the default to nil.

* lisp/emacs-lisp/checkdoc.el (checkdoc-message-text-next-string)
(checkdoc-message-text-engine): Flag formatting mistakes in warnings.
(checkdoc--warning-function-re): New variable.

* lisp/emacs-lisp/checkdoc.el (checkdoc-file-comments-engine):
Don't require a footer line unless 'lm-package-needs-footer-line'
returns true.

Provide the same functionality as 'async-shell-command-buffer' but for
'eshell-command'.
