79c86ae890 Support scaling of cursor sprites given what output they are on
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.

d3fdaa3232 MetaCursorSprite: Put renderer specific code in the renderer
There were lots of code handling the native renderer specific cases;
move these parts to the renderer. Note that this causes the X11 case to
always generate the texture which is a waste of memory, but his
regression will be fixed in a following commit.

The lazy loading of the texture was removed because it was eventually
always loaded anyway indirectly by the renderer to calculate the
current rect.

165050f8f9 backends: Get rid of meta-cursor-private.h
There is nothing special about the private API which only consists of
getters for renderer specific backing buffer. Lets them to the regular
.h file and treat them as part of the normal API.

4b667d1e09 Rename MetaCursorReference to MetaCursorSprite
It isn't really a reference to a MetaCursor enum, but a reference
counted cursor sprite, and enum value.

229360b248 Start molding out a new src/backends/ dir
Right now this just has all of the files in one directory. We'll
be introducing more structure to this in the future, and build
a proper backend system.
