Subject: [PATCH] Implement FromVariant for Variant

This is useful when combined with the container variant functions and
trait implementations from https://github.com/gtk-rs/glib/pull/651.

Implementing `ToVariant` would be useful as well, but isn't currently
possible: https://github.com/gtk-rs/glib/issues/678
