When running on quartz, it is no longer expected for applications to
provide their own application menu. Instead, they should simply ensure
that they provide "app.about", "app.preferences" and "app.quit" actions
(which many apps are already doing).
A default menu will be shown that looks like the one presented by all
other Mac OS applications, containing menu items for the above actions,
as well as the typical "Hide app", "Hide Others and "Show All" items and
the "Services" submenu.
If an application does explicitly set an application menu (via
gtk_application_set_app_menu()) then it will be respected, as before.

Add support for extracting strings from GMenu markup in GtkBuilder
files.
This means that we have to support translatable <attribute/> tags.
Unfortunately, <attribute> is also used by GtkTreeViewColumn and
GtkLabel for other purposes, and those other purposes use a value=''
(XML) attribute, so we must accept (and ignore) that in order not to
have errors. Nothing will happen in those cases because they do not
also specify translatable='yes', so we ignore them.

Add a new private API to GtkApplication akin to
gtk_widget_insert_action_group().
We'll use this to insert a few extra actions at the app level with a
separate namespace for the special items in the Mac OS application menu.

Add a private hack to allow the insertion of the name of the application
into the label of menu items.
If it appears in the label of any menu item, "%s" will be replaced with
the name of the application.
We will use this for the "Hide myapp", "Quit myapp" and "About myapp"
labels typically found on Mac OS programs.

Allow the possibility for items to be marked with a special attribute and
expose this via GtkTrackerMenuItem. For internal use only.
We will use this to implement the special 'Hide', 'Hide Others' and 'Show All'
items and the 'Services' submenu in the Mac OS application menu.

By default, Mac OS scans menus as they are opened, updating the
sensitivity of each item in the menu.
The current code in gtkapplication-menu-quartz disables this behaviour,
preferring to manually control the sensitivity of each item in the menu
(when told by the tracker that it has changed internally).
Change the way that this works to more closely follow the usual Mac OS
regime.
This will allow us to construct a typical "application menu" on Mac OS
containing the items that are typically found there ("Hide", "Hide
Others", "Show All", "Services") and have the OS automatically update
their sensitivity.

Add a custom title had the side-effect of showing the widget.
That is not right, adding children and managing their visibility
should be independent. The headerbar size allocation code also
made the assumption that a custom title is always visible.
With these changes, GtkHeaderBar should be usable in situations
where the centering functionality is not required, and it is
important to freely pack content at both ends, such as in nautilus.

Use a GtkHeaderBar for the credits and about buttons.
It makes less sense here than in other places to go back to
the buttons on the bottom, considering we only have a close
button, so we always use a header bar.

This commit introduces a private convenience API that derived
dialogs can call in their instance init. This is necessary to
make the setting work as intended in the face of 3rd party
dialogs derived e.g. from GtkFileChooserDialog, which are
created with g_object_new.
This setting will let us keep traditional appearance
of dialogs on platforms where this is expected.
The new setting is called gtk-dialogs-use-header, backed
by the Gtk/DialogsUseHeader xsetting.
This change makes it possible for GtkDialog to pack
its action widgets into a header bar, instead of the
traditional action area. This change is controlled
by the use-header-bar construct-only property.

Stop trying to deal with "theoretical possibilities".
We can't possibly continue to be a faithful GActionGroup implementation
across dispose because dispose has a side effect of removing everyone's
signal handlers.
The code that we ran after the dispose chainup to do all of the fancy
signal emulation was therefore dead. The test that aimed to verify this
was buggy itself due to an uninitialised variable, so really, it never
worked at all.
We keep the re-ordering of the chainup from the original commit to avoid having
trouble with GtkActionMuxer and keep the checks in place that will prevent an
outright segfault in the case that someone else tries to use the interface
post-dispose.
