GtkMenuTracker folds a nested structure of sections in a GMenuModel into
a single linear menu, which it expresses to its user by means of 'insert
item at position' and 'remove item at position' callbacks.
The logic for where to insert separators and how to handle action
namespaces is contained within the tracker, removing the need to have
this logic duplicated in the 3 or 4 places that consume GMenuModel.
In comparison with the previous code, the tracker no longer completely
destroys and rebuilds menus every time a single change occurs. As a
result, the new gtkmenu testcase now runs in approximately 3 seconds
instead of ~60 before.

Make the main (and only) entry-point to gtkmodelmenu.c the now-public
gtk_menu_shell_bind_model().
Move the convenience constructors (gtk_menu_new_from_model() and
gtk_menu_bar_new_from_model()) to their proper files.
Remove the private header file.
Simplify the code a bit by making the initial populate part of the
bind() call.

Add an API to GtkAccelLabel for hardcoding the accel key to be displayed
(ie: allowing us to bypass the GtkAccelGroup lookup).
Use that from the GMenuModel-based GtkMenu construction code instead of
passing around the accel group.
This makes accel labels work in bloatpad again.
This patch effectively removes any hope of automatic runtime accel
changes in GMenuModel-based menus without additional application
support but it leaves the door open for this to be supported again in
the future (if we decide that it's important).

Add support for a stateful action associated with a submenu. The action
state is set to TRUE when the menu is shown and FALSE when it is
unshown.
This is useful to avoid unnecessary processing for menus that have
frequently-changing content.
A possible future feature is to add support for asynchronously filling
the initial state of the menu by waiting until the action actually emits
its state-change signal to TRUE before showing the menu.
A silly example has been added to Bloatpad to demonstrate the new
feature.

If a section or submenu item has a "action-namespace" attribute, the
action names of the created GtkModelMenuItems will be prefixed with that
namespace. Namespaces can be cascaded.
Drop the explicit passing of GActionGroup into the GtkMenu(Bar)
constructors and operate from the action context instead.
With GtkMenuItem implementing GtkActionable, this turns out to be pretty
easy (and most of the code can be removed from GtkModelMenuItem,
including the GActionObserver implementation).
Move internal accel map API there and update all users.
Also, add an internal function to create an accel path for
an action and parameter, and use it in gtkapplication.c and
gtkmodelmenuitem.c instead of duplicating that code.
Put this in a separate file and substantially refactor it.
Move handling of submenu creation into gtkmodelmenuitem where it
belongs.
Improve our handling of when to show separators or not.
GtkModelMenuItem, being based on GtkCheckMenuItem, was always reserving
space for a check/radio indicator. This ends up looking pretty strange
in a GtkMenuBar.
Don't reserve space for the indicator unless it's appropriate.
This GtkMenuItem subclass (and GActionObserver implementation) contains
all the knowledge necessary for converting a GMenuModel item description
into a GtkMenuItem.
Remove much of the code that used to do this from
gtkapplicationwindow.c.
