[bug#58499] [PATCH] gnu: add citra (stable version)

[florhizome <florhizome@posteo.net>]

Hi Liliana!
thx for the revision! I also have yuzu in the pipeline,
which is by the same/similar team, which makes this even more rewarding.

The next patch will remove all submodules that I was able to
remove. More could be done by replacing the rest under external/ with.
symlinks, I guess. Also, tests seem to work under x86, and using only
gst-plugins-bad-minimal in a wrapper seems to be enough to make the
camera work.

This leaves us with the repo/versioning and the discord issue.

After reading their repo-policy
The main repo is for development, the nightly one picks out stable
features, the experimental/canary one adds more unstable ones. By going with
"main" we basically skip any stability guarantees, that the devs are trying
to give.
For me personally, the version numbers are very helpful, since they make it easier
to track dependency changes.
The patch I am preparing will use 0 as main version, though.

Actually ffmpeg and sdl are not bundled in our version,
but later versions will bundle sdl again.

As far as I understand, there are other programs, and free alternatives
other then discord using its status protocol.

To me it looks like gpl2 only, am I overlooking something?
