Don't unset the surface->buffer if the associated wl_buffer object is
destroyed. The MetaWaylandBuffer doesn't really only represent a
wl_buffer object, but also the data (texture) created from the given
wl_buffer. Thus, for example destroying a released SHM wl_buffer should
not destroy the MetaWaylandBuffer instance, because the texture may
still be used.
This commit also fixes a race where calc_showing would hide a window
because, at the time of calculation whether it should be showing, the
surface's buffer had been destroyed as described above.

In destroy_data_offer() there is code to ensure compatibility when
dragging from a v3 wl_data_device to a v2 one, it's however not checking
correctly that this is the DnD drag source. The other path should be
used otherwise.

For the GDK backend We're using the GdkDeviceManager API, which maps to
Clutter's own device manager API. GDK has now moved to a per-seat device
management model, and deprecated the device manager singleton one.
In order to avoid the deprecation warnings, we'd have to implement a
model similar to the GDK one inside the generic Clutter API, but that
would also require moving all the others backend to it, which is pretty
pointless.
Instead, we can disable deprecation warnings for the
ClutterDeviceManager implementation inside the GDK backend.
This updates config.h.win32.in to be in-sync with the entries that are in
the config.h.in that is generated by the autotools builds. In particular,
for Visual Studio builds, we default to enable all available drivers ("*").
Add an additional MetaWaylandDataSource implementation for primary selection
sources, and methods to set primary selection offers. Primary selection
sets altogether a different channel than the clipboard selection, those don't
cross in any way.
Also, the bridge for the X11 PRIMARY selection atom has been added, which
adds all the necessary handling to translate primary selection both ways
with wayland and X11 applications.
https://bugzilla.gnome.org/show_bug.cgi?id=762560
This protocol is an internal mirror of the primary selection drafts
being proposed for wayland-protocols. No changes besides prefix/suffix
changes.

It indirectly triggers expensive operations in gnome-shell
(js/ui/keyboard.js), which turns out too expensive if we happen to operate
the shell simultaneously with 2 devices that will trigger the operations
there.
So just rate limit the signal emission, defer to an idle and just emit
the last device gotten. Worst that will happen is that we may possibly
emit the signal on the same device consecutively.

If a MetaLater callback queued another MetaLater with a scheduling
later than the one currently being invoked, make it so that the newly
scheduled callback will actually be invoked.
The fact that it doesn't already do this is a regression from
cd7a968093.

Separate from meta-test-runner which runs metatests testing window
manager operations, a new test program (mutter-unit-tests) is
introduced. This is meant to run unit test like tests on various units
in mutter.
An initial test testing the order of MetaLater callback invokation was
added.

The constraint may be destroyed before the client destroyes the
protocol object, for example if a oneshot constraint was disabled by
alt-tab. Therefore we need to NULL check the constraint in request
handlers and ignore any requests to defunct objects.
The function should return true not only if the actor is being painted
by a ClutterClone, but also if it's inside a sub-graph being painted by
a ClutterClone.

commit 188752158 changed cogl to stop needlessly creating its own
monitor output configuration when mutter would just soon overwrite
it anyway.
Unfortunately, that commit is causing a crash in some cases because
cogl will now create and later draw to a 0x0 egl surface until mutter
sets the monitor layout.
This commit changes cogl to avoid creating and using a surface, before
it knows how big of a surface to create.

As of "core: start as wayland display server when
XDG_SESSION_TYPE=wayland" it is no longer possible to run a nested
mutter Wayland session on top of another Wayland session. This patch
adds a command line argument to make it possible to force mutter to
start as a nested compositor.
https://bugzilla.gnome.org/show_bug.cgi?id=758658
Add a gtk_shell.set_startup_id request, so the application can communicate
to the compositor the startup id that it received through the
DESKTOP_STARTUP_ID envvar, or other means.

This is kind of in a middle ground at the moment. Even though it
handles sequences not coming from libsn, they're added nowhere at
the moment, we'll rely on the app launch context being in the x11
side at the moment.
Also, even though we do create internal sequence objects, we keep
exposing SnStartupSequences to make gnome-shell happy, we could
consider making this object "public" (and the sequence objects with
it), things stay private at the moment.

Since a buffer can be used by multiple surfaces at once,
we need to release the buffer only after all surfaces
are finished with it. Currently we track whether or
not to release the buffer based on the accessible boolean.
This commit changes it to a counter to accomodate multiple
users.
Also, each surface needs to know whether not it is done with
the buffer, so this commit adds a buffer_used boolean to the
surface state.
https://bugzilla.gnome.org/show_bug.cgi?id=761613
We currently track whether or not a buffer can be released early
by looking at the copied_data boolean on the buffer. This boolean
is, practically speaking, always set to TRUE for shm buffers and is
always false otherwise.
We can just as easily check if the buffer is a shm buffer to decide
whether or not to do an early release. That's better from a
theoretical point of view since copied_data assumes a 1-to-1
relationship between surface and buffer, which may not actually hold.
This commit drops copied_data and changes the check to instead see
if the buffer is shm.

If a broken or naughty application tries set up its windows to create
a loop in the transient relationship, mutter will hang, looping forever
in meta_window_foreach_ancestor()
To avoid looping infinitely at various point in the code, check for a
possible loop when setting the transient relationship and deny the
request to set a window transient for another if that would create a
loop.
