To find XWayland output that should be the primary one, iterate through all
XWayland outputs, and compare their geometry to the geometry of the primary
logical monitor.
To avoid possible race conditions (Mutter's monitor configuration already
updated, but Xrandr not yet), set the output both after Randr notifications and
after 'monitors-changed' signal.

We artificially made Xwayland initialization synchronous, as we used
to rely on MetaX11Display and other bits during meta_display_open().
With support for Xwayland on demand and --no-x11, this is certainly
not the case.
So drop the main loop surrounding Xwayland initialization, and turn
it into an async operation called from meta_display_init_x11(). This
function is turned then into the high-level entry point that will
get you from no X server to having a MetaX11Display.
The role of meta_init() in Xwayland initialization is thus reduced
to setting up the sockets. Notably no processes are spawned from here,
deferring that till there is a MetaDisplay to poke.

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.
X11 client windows now hook a X11-specific MetaWaylandDragDestFuncs
that converts these into Xdnd* messages, and an additional selection
bridge has been added to take care of XdndSelection, and the data
transfers done through it.

This piece of code hooks in both wl_data_device and the relevant X
selection events, an X11 Window is set up so it can act as the clipboard
owner when any wayland client owns the selection, reacting to
SelectionRequest events, and returning the data from the wayland client
FD to any X11 requestor through X properties.
In the opposite direction, SelectionNotify messages are received,
which results in the property contents being converted then written
into the wayland requestor's FD.
This code also takes care of the handling incremental transfers through
the INCR property type, reading/writing data chunk by chunk.

This adds support for running mutter as a hybrid X and Wayland
compositor. It runs a headless XWayland server for X applications
that presents wayland surfaces back to mutter which mutter can then
composite.
This aims to not break Mutter's existing support for the traditional X
compositing model which means a single build of Mutter can be
distributed supporting the traditional model and the new Wayland based
compositing model.
TODO: although building with --disable-wayland has at least been tested,
I still haven't actually verified that running as a traditional
compositor isn't broken currently.
