Let's make it really simple and ask user interactively, once. This
simplifies things for:
* Privacy panel of gnome-control-center as it doesn't have to filter
applications.
* Apps: If they are denied access, they can simply point users to
privacy panel of gnome-control-center since they can be sure location
access for the app can be enabled in there.
Also it's less annoying to user. Before this patch, if they denied
access to application, they had to keep doing that at least each time
they launched the application.

Alex told me that since it's not geoclue but rather GNOME-components
storing/accessing app permissions, it's better if we put it under
'gnome' rather than generic 'desktop' table.
Now that we no longer skip dimming/undimming windows while showing
the overview, we can still save a bit of work by changing the dimming
without animation while the window is hidden.

We skip window animations while the overview is shown (and the window
group is hidden) to avoid unnecessary work. However when an attached
modal dialog is opened or closed, this involves checking whether the
parent window should be dimmed - skipping that test means that we can
simply fail to dim or undim a window altogether, so do that check
unconditionally.

While we could have implemented this already a while ago, this would
have been a completely false security mechanism since we had no way of
reliably identifying applications. Since now with xdg-app, we can at least
reliably identify bundled applications, let's give users a choice of
which applications in particular they are OK with giving location data
to.
While we still can't reliably identify system (non-xdg-app) applications,
it seems extremely unlikely we'll ever be able to do that (at least not
in the near future) so we'll have to trust them to not lie about their
IDs.
Next release of geoclue will take the ID of bundled application directly
from corresponding xdg-app metadata so bundled applications can't simply
lie about their IDs.
