For GNOME Shell, we need to grab our DBus names *before* we talk XSMP.
gnome-session takes our XSMP connection as "I'm ready", and starts
running all the other random crud that people dropped in as autostart
files. But for example, we need to have claimed
org.freedesktop.Notifications before a lot of said crud starts.
This requires a plugin API version bump.
Misc: Move handling of --version way earlier in main() where
it should be; no point having it wedged after plugin handling.
If a plugin was explicitly specified, falling back to the default
silently is bad; a manager component like gnome-session can
do a better job of handling this scenario.
An example we've hit in gnome-shell is where SpiderMonkey changes
without gjs being rebuilt, and loading the plugin fails due to
unresolved symbols.
But there are obviously others, like the file being missing or
corrupt.

Move all objects and functions namespaced with Mutter into the Meta namespace
to get a single consistent namespace. Changes that aren't simply changing mutter
to meta:
MutterWindow => MetaWindowActor
mutter_get_windows => meta_get_window_actors
mutter_plugin_get_windows => meta_plugin_get_window_actors
