It was just pointer to the actual list; having to synchronize a list of
logical monitors with the actual monitors managed by the backend is
unnecessary.

In preparation for further refactorizations, rename the MetaMonitorInfo
struct to MetaLogicalMonitor. Eventually, part of MetaLogicalMonitor
will be split into a MetaMonitor type.

Use the proposed EGL_WL_wayland_eglstream EGL extension instead of the
file descriptor hack that was used as a temporary solution.
Note that this results in EGL clients will no longer work if they are
running on a Nvidia driver with a version older than 370.

We need to do swap notifications asynchronously from flip events since
these might be processed during swap buffers if we are waiting for the
previous frame's flip to continue with the current.
This means that we might have more than one swap notification queued
to be delivered when the idle handler runs. In that case we must
deliver all notifications for which we've already seen a flip event.
Failing to do so means that if a new frame, that only swaps buffers on
such a swap notification backlogged Onscreen, is started, when later
we get its flip event, we'd notify only an old frame which would hit
this MetaStageNative's frame_cb() early exit:
if (global_frame_counter <= presented_frame_counter)
return;
and we'd never finish the new frame and thus clutter's master clock
would be waiting forever stuck.

When flush-swap-notify is already queued, we might end up trying to
requeue it, for example when handling flip callbacks inside
swap-buffers. Actually queuing it there is harmless, since old frames
will be discarded anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=774923
We might still end up in swap-buffer without the previous flip callback
having been invoked. This can happen if there are two monitors, and we
manage to draw before having all monitor flip callbacks invoked.

This commit adds for a new type of buffer being attached to a Wayland
surface: buffers from an EGLStream. These buffers behave very
differently from regular Wayland buffers; instead of each buffer
reperesenting an actual frame, the same buffer is attached over and
over again, and EGL API is used to switch the content of the OpenGL
texture associated with the buffer attached. It more or less
side-tracks the Wayland buffer handling.
It is implemented by creating a MetaWaylandEglStream object, dealing
with the EGLStream state. The lifetime of the MetaWaylandEglStream is
tied to the texture object (CoglTexture), which is referenced-counted
and owned by both the actors and the MetaWaylandBuffer.
When the buffer is reattached and committed, the EGLStream is triggered
to switch the content of the associated texture to the new content.
This means that one cannot keep old texture content around without
copying, so any feature relying on that will effectively be broken.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
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.

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.

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.

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.

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

Enabling edge scrolling before disabling two finger would result in
edge scrolling not actually being enabled because two finger is still
enabled at the time and we bail out.
This patch moves this logic to common code for both the native and X
backends and fixes it by ensuring that both settings are never set at
the same time and still re-checking if edge scrolling should be
enabled after two finger scrolling gets disabled.
We also simplify the code by not checking for supported/available
settings since the underlying devices will just reject those values
and there isn't anything we can do about it here. It's the UI's job to
only show supported/available settings to users.
https://bugzilla.gnome.org/show_bug.cgi?id=771744
Checking for supported methods isn't needed since libinput will just
error out and do nothing itself if a requested method isn't supported
and, in fact, this logic was preventing the enum values 0 from being
set.
