e12400a675 Add a hwcomposer backend based on libhybris
This backend interacts with libhybris to create a hwcomposer which is
used for creating the egl context and surface. The initial version of
this backend is based on test_hwcomposer.cpp provided by libhybris.

Please note that using the hwcomposer backend requires a newer libepoxy,
the latest stable release is not able to bring up OpenGLES, so one needs
a master build of libepoxy.

Notes on licensing:
libhybris is Apache 2.0 licensed, which is not compatile with GPLv2.
But it is compatible with GPLv3. Thus the source files in the hwcomposer
backend are licensed GPLv3+ and not GPLv2+ as the rest of KWin. If one
uses KWin without the hwcomposer backend (which is obviously the default)
the licence doesn't change. But if the hwcomposer backend is used the
overall license of KWin changes to GPLv3+.

877c33fe7d Initial implementation of EglGbmBackend
Uses EGL_MESA_platform_gbm to get an EglDisplay from a gbm_device.
The DrmBackend can provide a DrmBuffer for a gbm_surface and present
it.

Unfortunately buffer age seems to be slightly broken and we still have
artefacts.

c759551340 [wayland] Add a basic drm/kms backend
Introduces a new (optional) dependency: libdrm.

The DrmBackend currently supports finding the first connected output.
It can create shared memory buffers which are used by SceneQPainter to
do double buffered rendering.

There is still lots to do, the following things are not yet working:
* multiple outputs
* page flip
* OpenGL (through gbm)
* restoring mode setting to start value

706e22a12b Do not find OpenGL or OpenGLES
As we use epoxy we don't need them any more. KWin compiles, links and
runs just fine without ever trying to find OpenGL or OpenGLES.

c4bb3d11fc Initial support for libinput
Libinput is an optional dependency for getting low level input events.
As opening the input devices requires root privs this is rather
pointless in the current state. But there is a small added test app which
can be executed with root privs to demonstrate the functionality. To
properly get input events we need a wrapper like it's used in weston.

So far the following is setup:
* opening devices found by udev
* forwarding keyboard events to InputRedirection
* forwarding pointer button events to InputRedirection
* forwarding pointer axis events to InputRedirection
* signals emitted for pointer motion events

Pointer motion events need some further work as they are provided
as delta events. We need to track that and map them properly.

Also missing are touch events due to me not having a touch screen.
It should be fairly simple to setup the touch events, though.

Also hotplugging of devices is not yet implemented.

That's the version required in Qt 5.3 and causing issues if there's a
mismatch in versions.
