Add support for sending relative pointer motion deltas to clients who
request such events by creating wp_relative_pointer objects via
wp_relative_pointer_manager.
This currently implements the unstable version 1 from wayland-protocols.

This commits refactors cursor handling code and plugs in logic so that
cursor sprites changes appearance as it moves across the screen.
Renderers are adapted to handle the necessary functionality.
The logic for changing the cursor sprite appearance is done outside of
MetaCursorSprite, and actually where depends on what type of cursor it
is. In mutter we now have two types of cursors that may have their
appearance changed:
- Themed cursors (aka root cursors)
- wl_surface cursors
Themed cursors are created by MetaScreen and when created, when
applicable(*), it will extend the cursor via connecting to a signal
which is emitted everytime the cursor is moved. The signal handler will
calculate the expected scale given the monitor it is on and reload the
theme in a correct size when needed.
wl_surface cursors are created when a wl_surface is assigned the
"cursor" role, i.e. when a client calls wl_pointer.set_cursor. A
cursor role object is created which is connected to the cursor object
by the position signal, and will set a correct texture scale given what
monitor the cursor is on and what scale the wl_surface's active buffer
is in. It will also push new buffers to the same to the cursor object
when new ones are committed to the surface.
This commit also makes texture loading lazy, since the renderer doesn't
calculate a rectangle when the cursor position changes.
The native backend is refactored to be triple-buffered; see the comment
in meta-cursor-renderer-native.c for further explanations.

Instead of moving around all the bound pointer resources for a client
when changing focus, keep all the resources bound by a client in a per
client struct, and track the focus by having a pointer to the current
active pointer client struct instance.
This will simplify having wl_pointer extensinos sharing the pointer
focus of the wl_pointer by only having to add them to the pointer
client.

If a client creates an xdg_popup given a parent that is a xdg_popup that
is not the most top one in the grab chain, send the
not_the_topmost_popup error.
Also fail a client who destroys a popup that is not the top most one.
https://bugzilla.gnome.org/show_bug.cgi?id=744452
We'll want to expose popup logic outside of meta-wayland-pointer.c and
one day we'll also probably want to add touch support for popups, so
lets move it to its own file. There are no significant semantical
changes, only refactoring.
https://bugzilla.gnome.org/show_bug.cgi?id=744452
Sophisticated clients, like those using ClutterGtk, will have more
than one focused resource per client, as both Clutter and GDK will
ask for a wl_pointer / wl_keyboard. Support this naturally using
the same "hack" as Weston: multiple resource lists, where we move
elements from one to the other.
In order to support multiple pointers for the same client, we're
going to need to kill it.
This will cause crashes for now, but will be fixed by the next
commit.
meta_wayland_seat_repick() can be called in various cases while mutter
has a GRAB_OP ongoing which means we could be sending wrong pointer
enter/leave events.
https://bugzilla.gnome.org/show_bug.cgi?id=726123
Both the pointer/keyboard resource and surface resource can be destroyed
at any point in the destruction process, so we need to have destroy
listeners on both. To make the code easier to follow, rename ->focus
to ->focus_surface at the same time, and rearrange the code so that
the two of them are always grouped together.
Grabs are now slice allocated structures that are handled by
whoever starts the grab. They contain a generic grab structure
with the interface and a backpointer to the MetaWaylandPointer.
The grab interface has been changed to pass full clutter events,
which allowed to remove the confusion between grab->focus and
pointer->focus. Invidual grabs are now required to keep their
focus, and choose whoever gets the events.
https://bugzilla.gnome.org/show_bug.cgi?id=707863
Use the new Clutter hook to make sure the pointer never enters
the dead area caused by the different monitor sizes.
You don't realize how much X is doing for you until you lose it...

We had an assertion in meta_wayland_surface_free() that after
a repick() we would not choose the freed surface, but that didn't
consider surfaces destroyed while holding the implicit pointer
grab (ie, because the user clicked on the X button). In that case,
we need to bypass the grab infrastructure and explicitly unfocus
the dead surface.
https://bugzilla.gnome.org/show_bug.cgi?id=706982
Calling XIGrabDevice has no effect under wayland, because the
xserver is getting events from us. Instead, we need to use our
own interfaces for grabs.
At the same time, we can simplify the public API, as plugins
should always listen for events using clutter.

This copies the basic input support from the Clayland demo compositor.
It adds a basic wl_seat implementation which can convert Clutter mouse
events to Wayland events. For this to work all of the wayland surface
actors need to be made reactive.
The wayland keyboard input focus surface is updated whenever Mutter
sees a FocusIn event so that it will stay in synch with whatever
surface Mutter wants as the focus. Wayland surfaces don't get this
event so for now it will just give them focus whenever they are
clicked as a hack to test the code.
