Stop ffap-machine-at-point from pinging random hosts

Having this on by default is highly problematic from a security and
privacy standpoint, as it risks having outgoing traffic that could
potentially reveal sensitive data (passwords, names, etc.).

It also seems to be causing issues for users, see e.g.
https://github.com/emacs-helm/helm/issues/648

* lisp/ffap.el (ffap-machine-p-known): Change default to 'accept'.

Add :safe property to ffap-machine-p-* variables

(ffap-machine-p-local, ffap-machine-p-known)

Avoid obsolete initial-input argument in net-utils.el

* lisp/net/net-utils.el (ping, nslookup-host, dns-lookup-host)
(run-dig, ftp, smbclient, smbclient-list-shares, finger)
(network-connection-to-service): Don't use obsolete initial-input
argument.  Use 'format-prompt'.  (Bug#56436)

Improve behavior of sticky tooltips on Haiku

* src/haiku_support.cc (class EmacsView, MouseMoved): Remove
`tooltip_position'.
(class EmacsMotionSuppressionView): New class.
(BView_set_and_show_sticky_tooltip): Rename to
`be_show_sticky_tooltip'.  Add motion suppression view.

* src/haiku_support.h: Update prototypes.
* src/haikufns.c (Fx_show_tip): Update for renamed function.

Fix flickering system tooltips on Haiku

* src/haiku_support.cc (class EmacsView, MouseMoved): Restore
sticky status and mouse relative position.
(BView_set_and_show_sticky_tooltip):
* src/haikufns.c (haiku_hide_tip): Fix coding style.

Reduce synchronization setting frame alpha

* src/xterm.c (x_set_frame_alpha): Don't synchronize while
setting alpha property, and don't ask for the current value of
the opacity property, which is much more expensive than changing
it.

Merge from origin/emacs-28

2ac0ddc4ac ; * lisp/net/net-utils.el: Minor doc fixes.

Fix returned action symbol upon "xterm" drop

* src/xterm.c (x_dnd_do_unsupported_drop): Set
x_dnd_action_symbol.

* lisp/emacs-lisp/ert.el (Commentary): Refer to the Info manual.

Prefer keymap inheritance in shr-image-map

* lisp/net/shr.el (shr-image-map): Replace copy-keymap with
inheritance.

Make imenu--create-keymap more resilient

* lisp/imenu.el (imenu--create-keymap): Ignore nil items in the
alist (bug#56430).

Fix buffer-tests

* test/src/buffer-tests.el (test-restore-buffer-modified-p): Don't
assume turning on auto-save-mode cannot auto-save immediately.

Faster append and vconcat

By separating the code paths for append and vconcat, each becomes
simpler and faster.

* src/fns.c (concat_strings): Rename to...
(concat_to_string): ...this.
(concat): Split into concat_to_list and concat_to_vector.
(concat_to_list, concat_to_vector): New, specialised and
streamlined from earlier combined code.
(concat2, concat3, Fappend, Fconcat, Fvconcat): Adjust calls.

Remove obscure, obsolete code from do_switch_frame

This is relevant for bug #56305, and might solve that bug.  The code being
removed went into Emacs between 1992 and 1994, and looks to have been a
workaround for switching frames, before the command 'other-frame' had been
written.  Nowadays, that code has harmful effects, causing frames' focus to be
redirected at random, sometimes back to the frame itself.

* src/frame.c (do_switch_frame): Remove 53 lines of code.

* lisp/net/dig.el (dig): Provide default.

Make net-utils-url at point funs obsolete in favor of ffap

* lisp/net/net-utils.el (net-utils-machine-at-point)
(net-utils-url-at-point): Redefine as obsolete function alias for
'ffap-machine-at-point' and 'ffap-url-at-point'.  Update callers.
* lisp/ffap.el (ffap-machine-at-point, ffap-url-at-point): Autoload.

Fix selection disowning upon frame deletion on Wayland

* src/pgtkselect.c (pgtk_clear_frame_selections): Manually
disown cleared selections.  (bug#56434)

* lisp/net/eww.el (eww-browse-url): Add 'browser-kind' property.

* lisp/woman.el (woman): Fix comment; don't mention gnudoit.

Make two XEmacs related variables obsolete

* lisp/net/browse-url.el (browse-url-gnudoit-program)
(browse-url-gnudoit-args): Make obsolete.  The corresponding command
'browse-url-w3-gnudoit' is already obsolete since 25.1.

Fix GTK build

* src/xterm.c (x_dnd_begin_drag_and_drop): Update GTK quitting
code for last change too.  Reported by Norbert Koch
<viteno@netic.de>.

Fix quitting out of selection converters during drag and drop

* src/xterm.c (x_dnd_process_quit): New function.
(x_dnd_begin_drag_and_drop): Use it instead.  Also quit if
quit-flag is true immediately after a selection converter is
run.

Mark comint modes in net-utils.el as non-interactive

* lisp/net/net-utils.el (net-utils-mode, nslookup-mode, ftp-mode)
(smbclient-mode, network-connection-mode): Mark as non-interactive.
(nslookup-mode-map, ftp-mode-map): Prefer defvar-keymap.

; * lisp/net/net-utils.el: Minor doc fixes.

Make 'run-dig' command obsolete in favor of 'dig'

* lisp/net/net-utils.el (run-dig): Redefine in terms of `dig' and make
obsolete.  (Bug#56432).
(dig-program): Delete duplicate defcustom; it is also in dig.el.
(dig-program-options): Move from here...
* lisp/net/dig.el (dig-program-options): ...to here.
(dig-invoke): Respect 'dig-program-options'.
(dig): Prompt for DNS server when given double prefix argument.

Fix undo of changes in cloned indirect buffers

* lisp/simple.el (primitive-undo): If the visited-modtime of the
indirect buffer's file is bogus, use the modtime of the file
visited by its base buffer.

* src/undo.c (record_first_change): Call
'buffer_visited_file_modtime' with the correct buffer, instead of
always calling 'Fvisited_file_modtime', which returns possibly
bogus values for indirect buffers.
* src/fileio.c (Fset_visited_file_modtime): Signal a meaningful
error for indirect buffers.
(buffer_visited_file_modtime): New function, with implementation
taken from 'Fvisited_file_modtime'.
(Fvisited_file_modtime): Call 'buffer_visited_file_modtime'.
* src/lisp.h: Add prototype for 'buffer_visited_file_modtime'.
(Bug#56397)

* lisp/net/dig.el (dig-exit): Mark for 'dig-mode'.

Make the Indian itrans methods more phonetic

The characters ऋ and ॠ are pronunced as ru in languages such as
Marathi, Gujarati, Telugu, etc. so add new translation rules that
reflects this sound.  (bug#56414)

* lisp/language/ind-util.el (indian-itrans-v5-table): Add new
translation rules to make the input method more phonetic.
(indian-tml-base-table, indian-tml-base-digits-table): Fix typo.

Merge branch 'master' of git.savannah.gnu.org:/srv/git/emacs

Don't accumulate trailing newlines on every save of .dir-locals.el

* lisp/files-x.el (modify-dir-local-variable): Insert a newline
only after creating a new file.
