Automatically choosing a VT for DRM compositor?

[Matt Hoosier]

It would be nice for non-session uses of Weston (embedded systems) if
the controlling TTY didn't need to be manually supplied.

Has anybody suggested using something like VT_OPENQRY in the
weston-launcher code to pick a TTY if one wasn't manually given? (Or
if that's too auto-magic for taste here, then only do that if a
specific command-line option is supplied.)

The closest I can find to a question about this topic prior on the
mailing list is
https://lists.freedesktop.org/archives/wayland-devel/2013-October/011472.html.
That change was never adopted, but it doesn't look like the use of
VT_OPENQRY has anything to do with Kristian's objections at the time.
