[PULL 04/40] ui: Mark the '-no-quit' option as deprecated

From: Paolo Bonzini
Subject: [PULL 04/40] ui: Mark the '-no-quit' option as deprecated
Date: Tue, 6 Jul 2021 12:01:05 +0200

From: Thomas Huth <thuth@redhat.com>

It's just a wrapper around the -display ...,window-close=off parameter,
and the name "no-quit" is rather confusing compared to "window-close"
(since there are still other means to quit the emulator), so we should
rather tell our users to use the "window-close" parameter instead.

While we're at it, update the documentation to state that
"-no-quit" is available for GTK, too, not only for SDL.
