privacy standpoint, as it risks having outgoing traffic that could
potentially reveal sensitive data (passwords, names, etc.).

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.

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.

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

run.

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

* lisp/net/net-utils.el (net-utils-mode, nslookup-mode, ftp-mode)
