We may need to check if rectangles region has adjacent neighbors and
so if there are no gaps in between monitors.
This can be done by checking if each monitor is adjacent to any other in
the same region.

MetaGravity is an enum, where the values match the X11 macros used for
gravity, with the exception that `ForgetGravity` was renamed
`META_GRAVITY_NONE` to have less of a obscure name.
The motivation for this is to rely less on libX11 data types and macros
in generic code.

Meta rectangles are integer based while clutter works in floating coordinates,
so when converting to integers we need a strategy.
Implement the shrink strategy by ceiling the coordinates and flooring the width,
and the grow strategy reusing clutter facility for this.

Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
To be able to render the pointer cursor sprite at sub-(logical)-pixel
positions, track the pointer position using floats instead of ints.
This also requires users of the cursor sprite rect to deal with
floating points, when e.g. finding the logical monitor etc.

Logical monitors in a configuration must be adjecent to each other,
meaning there will be at least one pixel long side touching some other
logical monitor.
The exception to this is when there is only one logical monitor, which
cannot be adjecent to any other.

They are already effectively interchangeable so this should reduce
pointless casts.
Just like in GDK though, we need to keep the old definition for
instrospection to be able to include the struct's fields.
Add support for drawing a stage using multiple framebuffers each making
up one part of the stage. This works by the stage backend
(ClutterStageWindow) providing a list of views which will be for
splitting up the stage in different regions.
A view layout, for now, is a set of rectangles. The stage window (i.e.
stage "backend" will use this information when drawing a frame, using
one framebuffer for each view. The scene graph is adapted to explictly
take a view when painting the stage. It will use this view, its
assigned framebuffer and layout to offset and clip the drawing
accordingly.
This effectively removes any notion of "stage framebuffer", since each
stage now may consist of multiple framebuffers. Therefore, API
involving this has been deprecated and made no-ops; namely
clutter_stage_ensure_context(). Callers are now assumed to either
always use a framebuffer reference explicitly, or push/pop the
framebuffer of a given view where the code has not yet changed to use
the explicit-buffer-using cogl API.
Currently only the nested X11 backend supports this mode fully, and the
per view framebuffers are all offscreen. Upon frame completion, it'll
blit each view's framebuffer onto the onscreen framebuffer before
swapping.
Other backends (X11 CM and native/KMS) are adapted to manage a
full-stage view. The X11 CM backend will continue to use this method,
while the native/KMS backend will be adopted to use multiple view
drawing.

If mutter is going to be a "real" library, then it should install its
includes so that users can do
#include <meta/display.h>
rather than
#include <display.h>
So rename the includedir accordingly, move src/include to src/meta,
and fix up all internal references.
There were a handful of header files in src/include that were not
installed; this appears to have been part of a plan to keep core/,
ui/, and compositor/ from looking at each others' private includes,
but that wasn't really working anyway. So move all non-installed
headers back into core/ or ui/.

Remove --allow-unprefixed option to the scanner, and fix resulting
problems:
* theme.h and boxes.h are split into a main -header and a private
header that includes stuff that is not generally useful and
hard to introspect. Merge theme-parser.h into theme.h.
* meta_display_get_atom() and meta_window_get_window_type_atom()
are marked as (skip)
* Fix annotation: (element-type Strut) => (element-type Meta.Strut)
