weston-info as a standalone utility

[Olivier Fourdan]

Hi all,

A long time ago [1], I suggested that we move weston-info out of the
Weston source tree because this is a very useful tool which gives
important information about any Wayland compositor, not just Weston.

The general consensus was it was a good idea, unfortunately other more
important things happened, people (including me) eventually forgot
about that and it never actually came to fruition…

But the need remains, I think we should have a compositor agnostic
tool that gives the general information about the running compositor.
And we should not need to install Weston for that alone.

So I took the liberty to uproot weston-info, rename it as wayland-info
and put it on its own repo:

https://gitlab.freedesktop.org/ofourdan/wayland-info

As you can see, I took great care to preserve the git history of
weston-info in the process.

In the meantime, Peter has already submitted patches to wayland-info
(thanks Peter!) so the tip of wayland-info is different from
weston-info (basically, we have diverged already).

Eventually, if nobody has objections, we could move that repo to the
wayland domain…

Cheers,
Olivier.
