This commit adds support for using a EGLDevice and EGLStreams for
rendering on top of KMS instead of gbm. It is disabled by default; to
enable it pass --enable-egl-device to configure.
By default gbm is first tried, and if it fails, the EGLDevice path is
tried. If both fails, mutter will terminate just as before.

There is no way to pass any backend specific parameters to a
CoglFramebuffer until after it has been allocated by
cogl_framebuffer_allocate() (since this is where the winsys/platform
fields are initialized). This can make it hard to actually allocate
anything, if the platform depends on some backend specific data.
A proper solution would be to refactor the onscreens and framebuffers to
use a GObject based type system instead of the home baked Cogl one, but
that'll be left for another day. For now, allocate in two steps, one to
allocate the backend specific parts (MetaOnscreenNative), and one to
allocate the actual onscreen framebuffer (via
meta_onscreen_native_allocate()).
So far there is nothing that forces this separation, but in the future
there will, for example EGLDevice's need to know about the CRTC in
order to create the EGLSurface.

A swap-buffers should never be issued when we are waiting for a flipped
callback, so instead of trying to handle a situation that sholud never
happen, warn instead.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
When a swap failed with EACCES (possibly due to VT switching), don't
mark the framebuffer as 'in use', so that it'll be cleaned up properly
and not set as current.

For when there is no gbm available, for example when using
EGLDevice/EGLStream's, just fall back to the OpenGL texture based
cursor rendering path.

Drivers may be bad at guessing what is passed to eglGetDisplay, ending
up return non-functioning EGLDisplay's. Using eglGetPlatformDisplay
avoids this issue.

Lets use a pbuffer surface as a dummy surface instead of a gbm based
one, so that we don't need to rely on the availability of gbm to create
a dummy surface when there is no need for it.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
Separate gbm initialization from general renderer initialization. Do
this even though no other initialization is done for now; later there
will will be other types of rendering mode, initialized in their own
functions.

Add proc symbol loading and helper functions for calling them, dealing
with errors etc. So far no extension symbols are loaded, only the
infrastructure is there.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
In another step getting rid of the duplications introduced by Cogl,
use the equivalent GLib types where Cogl types previously used. While
CoglBool is not a typedef to gboolean, they are both typedefs to int,
and we already use GLib's TRUE/FALSE to set them.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
Initialize the GError pointer used when creating the renderer. If an
error occurs, the error is expected to be NULL, otherwise it'll
misinterpreted as already set.

Similarly to Weston (where this code originated), there were two errors
in the X11 lockfile handling.
Firstly, after reading 11 characters from the lock file (which could
have been placed by any process), there was no guarantee of
NUL-termination, meaning strtol could've theoretically run off the end
of the string.
Secondly, whilst writing the new lock, the trailing NUL byte was not
correctly accounted for. The size passed as an input to snprintf takes
the maximum size of the string including the trailing NUL, whilst the
return (and the input to write) gives the actual size of the string
without the trailing NUL.
The code did attempt to check the return value, however snprintf returns
the size of the _potential_ string written, before snprintf culls it, so
this was off by one, and the LF was not being written.

In that case, the MetaWindow is created, but it should also be unminimized
to satisfy the MapRequest triggered by the client, otherwise these would
stay minimized until they're shown explicitly by the user.

Some applications like Wine may choose to juggle the same user time
window across different toplevels, in that case we receive warnings
when trying to register the window a second time, leading to wrong
accounting.
If the window was already used as the user time window for another
toplevel, unset it from the previous MetaWindow owner, and unregister
so the registration with the new MetaWindow is successful.

This is implemented using Wacom-driver specific properties at
the moment, until libinput becomes the fallback driver handling
tablet and pad management.
Whenever a tool becomes in proximity, a new ClutterInputDeviceToolXI2
will be created (if it wasn't created previously) for the given
serial number. This tool will be set in all events send from the
device.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
The Clutter X11 backend can't drop CLUTTER_PEN_DEVICE and
CLUTTER_ERASER_DEVICE in favor of CLUTTER_TABLET_DEVICE without
losing information (as the driver will create one device for each).
So make MetaInputSettings cater for both sets of device types.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
Its only purpose was caching settings applying to an stylus/tool, this
is now handled through ClutterInputDeviceTool evdev specific API, or
X device properties, so is not needed anymore.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
Stylus configuration (stylus buttons, pressure) was handled
at the very high level, doing the button and pressure translations
right before sending these to wayland clients.
However, it makes more sense to store these settings into the
ClutterInputDeviceTool itself, and have clutter apply the config
at the lower level so 1) the settings actually apply desktop-wide,
not just in clients and 2) X11 and wayland may share similar
configuration paths. The settings are now just applied whenever
the tool enters proximity, in reaction to
ClutterDeviceManager::tool-changed.
This commit moves all handling of these two settings to
the clutter level, and removes the wayland-specific paths
https://bugzilla.gnome.org/show_bug.cgi?id=773779
We do so whenever a tool enters or leaves proximity. We now also
ensure that last_tool is NULL after it leaves proximity, although
the CLUTTER_PROXIMITY_OUT event itself should still contain tool
information.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
And remove the wayland-specific handling. This works for both Wayland and
X11 (provided the compositor receives pad events through a passive grab
there).
https://bugzilla.gnome.org/show_bug.cgi?id=773779
We most notably handle button events (acquired through a passive grab on
all device buttons) which are translated to CLUTTER_PAD_BUTTON* events,
so there is generic handling of pad actions on X11.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
We kind of rely on the ::show-pad-osd handler to destroy the
previous actor. Just prevent the emission of multiple signals
till the actor has been destroyed.
https://bugzilla.gnome.org/show_bug.cgi?id=771067
Wayland popup grabs, unlike other grab types, can be safely cancelled
so there's no reason to deny compositor grab requests if a wayland
popup is on.
In particular, this allows entering the overview via a keybinding or
locking the screen while a wayland popup has a grab which is something
that's been advertised as a wayland improvement over X.
