This allows specifying if the results should be activated by clicking on
the result, or if that should only emit a selection event.

This is trying to be somewhat like a browser, so lets tweak things so that
we can have an example of epiphany.

The goal is for this to be used to notify when a suggestion was selected
due to user input. There are still some more corner cases to handle, such
as when we press with a button on a row, but that requires more changes to
the popover as well.

This allows subclasses to change the behavior by not chaining up to the
parent handler.

This can be used by the DzlSuggestionEntry to ensure that we clean the
suggestion state so that it doesn't show up upon next focus.

This allows for notify::suggestion signal callbacks when the selected entry
changes.

Install stuff properly when using project_subdir

See merge request GNOME/libdazzle!14

Otherwise it will conflict with the primary installation of libdazzle.
It should go in the private libdir that's already computed in the
toplevel meson.build.

dazzle-list-counters needs to be installed respecting package_subdir, so
it doesn't clash with the main installation of libdazzle.

I notice there are not currently any subdirectories in my /usr/bin, so
to avoid setting a precedent for having directories there, let's use
libexec instead when package_subdir is set.

This implements the focus vfunc instead of relying on the set_focus_chain()
to get the movement semantics.

These were flipped.

This removes the use of the focus chain and instead uses the focus vfunc
to implement focus movement.

All this code will have to be revamped for Gtk4, so no need to keep track
of things here. We will just update them whole-sale for gtk4 in the future.

Change strict key state check to CONTROL and SHIFT mask only. Without this
change also NUM key is considered and TAB completion will not work with NUM pad turned on.

Fixes: GNOME/libdazzle#22

This adds more tests to ensure we're not following symlinks through a
directory.

This ensures that we also handle some other variants like when the model
is set or when we have signal ordering that could perhaps keep us from
having widgets created by models yet.

Fixes: GNOME/libdazzle#21

This allows async loading of icons where the caller only needs to
g_object_notify() for "icon" to ensure that the view updates the image.

Clears text before signaling prevents accidential text removal.

Fixes: GNOME/libdazzle#17

This helps us ensure that the tree is destroyed during cleanup which makes
tracking leaks easier.

We don't need to use dzl_clear_pointer() anymore now that GLib has access
to g_clear_pointer() that performs similar checks as dzl_clear_pointer().

We need to ensure that the grab does not disappear out from under us. We
also want to make sure that we have ownership of the widgets during the
processing of the events.

This adds a new reference to self during the operation, and references all
the potential widgets before doing notifications.

This variant is not floating, and therefore we need to release it.

g_variant_parse() does not return a variant with a floating reference. So
we must unref them ourselves. Aldo, don't try to ref_sink(), since that
just increments to 2, and is not what we want.
