Add an api to retrieve the model containing a given
item in a flatten listmodel. This is useful when the
individual items in the list don't have backpointers.
We need to cleanup state here immediately so that we do not potentially
access the g_class private data after it been finalized. This ensures that
the borrowed reference is dropped by the muxer.
We used to either make the inspector see- and click-thru
or lower it, but sadly translucency broke after we
removed surface opacity, and lowering doesn't work
on Wayland. So just hide the inspector window while
we are picking.

When inserting Pango markup into a text buffer, translate
Pango attributes for overlines and hyphenation control
into the corresponding text tag properties.
Add support for recently added Pango attributes
for overlines and hyphenation control. The new
properties of GtkTextTag are
overline, overline-rgba, allow-breaks, show-spaces
and insert-hyphens.
Before this commit, adding GtkWidgetAction to class private data would
require copying the actions to each subclass as they were built or
modified. This was convenient in that it is a sort of "copy on write"
semantic.
However, due to the way that GTypeInstance works with base _init()
functions, the "g_class" pointer in GTypeInstance is updated as each
_init() function is called. That means you cannot access the subclasses
class private data, but only the parent class private data.
If instead we use a singly linked list of GtkWidgetAction, each subclass
has their own "head" yet all subclasses share the tail of the
GtkWidgetAction chain.
This creates one bit of complexity though. You need a stable way to know
which "bit" is the "enabled" bit of the action so we can track enabled
GAction state. That is easily solved by calculating the distance to the
end of the chain for a given action so that base classes sort ahead of
subclasses. Since the parent class always knows its parent's actions, the
position is stable.
A new dynamic bitarray helper also helps us avoid allocations in all the
current cases (up to 64 actions per widget) and dynamically switches to
malloc if that is to ever be exceeded.
We want access to the private data from the action muxer so we can just
move the structures to the gtkwidgetprivate.h header. Alternatively we
could create accessors, but given that we'll probably need to use this
in other areas, seems reasonable to just put it there.
For some reason, these tests are flaky in ci,
they always work locally for me. So, until
we use the data these tests produce for something,
lets just turn them off.
The problem is caused by gtk_im_multicontext_set_slave(), which forgets
to disconnect these signal handlers:
* gtk_im_multicontext_retrieve_surrounding_cb
* gtk_im_multicontext_delete_surrounding_cb
If slave GtkImContext emits signal after GtkIMMulticontext context is
destroyed, this leads to reading freed memory, sometimes causing a crash.

This makes meson actually parse the individual test
results. Most of the time, it does not make a difference,
but one case where it does is when all the individual
tests of a binary are skipped, meson will mark the
test as skipped.
The background-image-multiple.ref.ui file uses
non-existing properties, which gives us a g_warning,
and the glib test framework insists on treating
warnings as fatal, so we end up doing exit(133),
which in turn makes the meson TAP parser ignore
its xfails.
Comment out the nonexisting properties, so we can
fail properly, and then in turn xfail properly.
