The end goal is to have all clutter backend code in src/backends. Input
is the larger chunk of it, which is now part of our specific
MutterClutterBackendNative, this extends to device manager, input devices,
tools and keymap.
This was supposed to be nice and incremental, but there's no sane way
to cut this through. As a result of the refactor, a number of private
Clutter functions are now exported for external backends to be possible.

This means we need to make sure we don't accidentally free the provided
source GError (which automatically happens with `g_autoptr`), so use
`g_steal_pointer()`.
This fixes an issue where, when launched in a bubblewrap environment
(such as the one provided by Buildstream), mutter would give the
following warning message:
```
mutter-WARNING **: 8:31:35:069: Can't initialize KMS backend: (null)
```
... which isn't that useful when trying to debug the actual issue.
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.
And use the old "native" backend for both X11 and Wayland. This will
allow us to share fixes between implementations without having to delve
into the XSync X11 extension code.

Move finding, opening and managment of the KMS file descriptor to
MetaMonitorManagerKms. This means that the monitor manager creation can
now fail, both if more than one GPU with connectors is discovered, or
if finding or opening the primary GPU fails.

The caller in clutter really expects an error if fd==-1, so make
sure we set one here. Otherwise we get a nice crash in addition to
the failure to open the /sys file. Also, retry on EINTR.

Clutter assumed seat0 which is most usually, but not always correct.
Add an evdev-backend specific function to allow passing the seat
that will be used for ClutterDeviceManager construction, which we
already obtain in MetaLauncher.

commit e2bfaf0751 does this:
g_hash_table_insert (cards,
g_udev_device_get_name (parent_device),
g_steal_pointer (&parent_device));
The problem is the g_steal_pointer call may happen before the
g_udev_device_get_name call leading to a crash.
This commit does the get_name call on an earlier line
https://bugzilla.gnome.org/show_bug.cgi?id=771442
Right now we accept any character device that matches the glob card*.
That's fine, but we can be a little more specific by checking that
the devtype is what we expect.
This commit does that.

Despite g_udev_client_new taking a list of subsystems, it doesn't
implicitly filter results to those subsystems.
This commit explicitly adds a subsystem match to make sure sound cards
don't end up in the resulting list of video cards.

Move the KMS interaction from cogl into mutter, where most of the other
KMS interaction already takes place. This also removes dead code which
were only excercised when non-mutter callers used the cogl KMS backend.
The cogl KMS API was updated to pass via MetaRendererNative instead of
via the different cogl objects.
https://bugzilla.gnome.org/show_bug.cgi?id=768976
Instead of passing around the KMS file descriptor via clutter to cogl,
just make our own clutter backend create the cogl renderer and set the
KSM fd.

Sadly, GLib's autoptr cleanup macros cannot be detected by the C
pre-processor, because they generate a function. This means that we are
forced to bump up the dependency on GLib 2.49, in order to build against
a newer version of gdbus-codegen.
Starting from GLib 2.49, the gdbus-codegen tool automatically generates
the auto cleanup symbols for the GDBus proxy and skeleton interfaces.
Since we don't depend on a specific version of GLib we need to
conditionally generate the auto cleanup symbols in case an older version
of gdbus-codegen is used when building Mutter.
This commit unbreaks the build under GNOME Continuous, which has been
failing with:
usr/include/glib-2.0/glib/gmacros.h:415:43: error: redefinition of 'glib_autoptr_cleanup_Login1Session'

On Odroid U2 (exynos4412) the drm device is not bound to pci.
Open the detection to platform device of the drm subsystem, exclusive of
control devices.

g_error() is the wrong thing to do when, for example, we can't find the
DRM device, since Mutter should just fail to start rather than reporting
a bug into automatic bug tracking systems. Rather than trying to decipher
which errors are "expected" and which not, just make all failure paths
in meta_launcher_new() return a GError out to the caller - which we make
exit(1).

The qxl kms driver has a bug where the cursor gets hidden
implicitly after a drmModeSetCrtc call.
This commit works around the bug by forcing a drmModeSetCursor2
call after the drmModeSetCrtc calls.
This is pretty hacky and won't ever go upstream.

This allows creating the stage much earlier than it otherwise would have
been. Our initialization sequence has always been a bit haphazard, with
first the MetaBackend created, then the MetaDisplay, and inside of that,
the MetaScreen and MetaCompositor.
Refactor this out so that the MetaBackend creates the Clutter
stage. Besides the clarity of early initialization, we now have much
easier access to the stage, allowing us to use it for things such as
key focus and beyond.
This uses David Herrmann's new logind sessions interface to retrieve
fds for input devices, rather than using a custom setuid helper to do
the management. This vastly simplifies the interface.
This requires systemd v210, at least.
