If we have a GObject property that is also a GObject, we should be able
to view additional information on that object (even if the param spec
is read-only).
We were relying on indirectly getting notify when fontconfig
configuration changes, by GtkSettings translating the timestamp
change into a style-invalidation, which gets fed through the
css invalidation machinery. That machinery has gotten good enough
at optimizing away redundant changes that it no longer emits
::style-updated in this case.
So, instead make the font chooser listen directly to what it
cares about: the fontconfig change notification from GtkSettings.
We can use the GtkSettings:gtk-fontconfig-timestamp property to decide
whether or not we should reload fonts on style and screen changes. This
should avoid doing a lot of work with large font collections when only
the theme has changed.

Add a new API, gtk_popover_set_default_widget, that can be
used to make a widget act as default while the popover is
shown. This is useful in dialog-like popovers.

Making a container focusable is rarely the right thing to do.
It typically breaks the focus chain, and makes the container
contents unfocusable, as was the case here.
We have a number of cases where properties should have their
default value overridden in a subclass, but haven't because thats
annoying to do. We also have properties where the absence of
an explicit value has context-dependent meaning.
Add a list of exceptions for these cases.
The previous commit removed default-valued properties,
but apparently that has a negative effect for grid
packing properties, so put the explicit value back.
Just using tracker does not work well if you are searching in
non-indexed locations, such as git checkouts or network mounts.
Ideally, we'd decide the 'best' engine to use for each location.
Since that is not easy to do, just run them in parallel for now,
which is the same strategy that nautilus uses.
