When a menu self-destructs, free also the widget and struct menu.
As menus are self-destructing, it does not make sense to store the
window pointer, since we cannot clear it automatically. Therefore,
rename window_create_menu() to window_show_menu() that does not return
the window pointer. It also calls window_schedule_redraw() internally.
Fixes Valgrind reported memory leaks.
The alternative would be to explicitly destroy the menu in application's
menu callback.

Input devices may hold a pointer to the widget being destroyed. Reset
such pointers in widget_destroy().
This fixes a use-after-free in window_destroy(), if an application
destroys its widgets before the window.

Fix a memory leak reported by Valgrind, by destroying the window
decorations widget, if it exists.
All widget pointers returned from toytoolkit to the application should
be destroyed by the application explicitly.

With all input events going to widgets now, we can grab an input device
to a widget, so that all events are delivered to that widgets handlers.
This lets us implement the last bit of the menu behaviour, that is
the client side grabbing of events. The result is that we can now pop down
the menu when we receive clicks in the clients own windows and we
don't send motion and button events to other widgets.
This lands the basic behavior of the popup surface type, but there are still
a number of details to be worked out. Mainly there's a hardcoded timeout
to handle the case of releasing the popup button outside any of the
client windows, which triggers popup_end if it happens after the timeout.
Maybe we just need to add that as an argument, or we could add a new event
that fires in this case to let the client decide whether it ends the popup
or not.
Windows are supposed to be destroyed by the application explicitly.
Deferred tasks are not supposed to be added after returning from
display_run().
Destroy remaining wl objects (except input related will be in a
following patch).
Close the epoll fd.

Add a function to destroy the 'struct display', supposedly with all
contained resources, that are not explicitly created by the application.
The implementation at this time is incomplete. It does clean up the
following:
- xkb structure is freed (needs new libxkbcommon from git)
- EGL resources are freed
- wl_display is flushed and destroyed

Add a function, that schedules the display_run() event loop to break
out.
When display_exit() is called, processing continues as usual, until
currently waiting events and deferred tasks have been processed, and
sent requests are flushed. Then, display_run() will return.
This enables toytoolkit apps to handle their exit instead of just being
killed or call exit().

The Cairo documentation tells us to always call cairo_device_flush()
before using other rendering APIs on the cairo surface, especially where
the Cairo device shares state with us (that is, EGL and GL state in this
case).
Add a call to cairo_device_flush() into display_acquire_window_surface(),
which the toytoolkit offers for switching to native (GL) rendering.

Add output_configure_handler as a display property. This exposes only
configured outputs, that is the current mode info is already received,
to applications.
The handler is also called for mode changes on an existing output. This
simplifies the implementation in toytoolkit as we can defer the handler
calls from wl_output binding time to when we receive the current mode.
We do not need separate handlers for "new output" and "mode changed". A
plain "new output" handler would be problematic as the current mode is
not known yet.
Also add delete_handler hook for outputs, but that will never be called
for now, as the protocol lacks a way to signal output disconnections.

Since it is the desktop-shell plugin in the compositor that offers both
wl_shell global interface and wl_shell_surface interface, those are not
available on the tablet-shell plugin.
The tablet-shell client uses the toytoolkit, so toytoolkit must work
somehow even without wl_shell.
Turn all operations in toytoolkit that would require wl_shell or
wl_shell_surface into no-ops.
