The documented minimum GStreamer version for Qt Multimedia is 0.10.24,
however, the camerabin plugin actually required 0.10.32 to compile
successfully. The reason is mainly due to the GstEncodingProfiles
API, which is used to implement the audio and video encoding settings
controls. There's no hard requirement for that API anymore and the
aforementioned controls simply don't do anything when the GStreamer
version used to compile is older than 0.10.32.
A few other GStreamer calls had to be ifdef'd or replaced in order
to compile with 0.10.24.
Note that this patch only makes sure it compiles with older versions,
running the camerabin plugin with GStreamer < 0.10.32 is currently
untested and it might not work as expected.

Instead of always using xvimagesink as GStreamer backend for the
widget and window control (works only with X11), we now try to
pick a video sink that fits the current configuration.
It first tries a set of known video sinks that can work with
the Qt platform plugin in use. If none is available, it
dynamically picks a video sink available on the system that can be
used with our backend.
Even if the video sink is now picked in a smarter way, xcb is still
the only supported platform plugin. The reason is that it's the
only Unix plugin which can provide a valid native window handle.
Additional work is needed to support other plugins like wayland
or directfb.

It was the backend's responsibility to handle resource files in an
appropriate way. In practice, it was either not handled at all,
or implemented in an almost identical manner in every backend
that does handle it.
This is now dealt with in QMediaPlayer, always passing to the
backend something it will be able to play. If the backend has the
StreamPlayback capability, we pass a QFile from which it streams
the data. If it doesn't, we copy the resource to a temporary
file and pass its path to the backend.
