Android: fix setting the camera preview resolution.

- When the video capture resolution or the image capture resolution
  changes, we now always set the viewfinder resolution to the highest
  available one with the same aspect ratio as the capture resolution.
  We were previously not doing anything if the new capture resolution
  had the same aspect ratio as the current viewfinder resolution.
- Some devices don't support using a viewfinder resolution different
  from the video capture resolution. Make sure we handle this case.

GStreamer 1.0: fix frames being presented too many times.

Presenting a frame originates from a gstreamer thread, we block there
until the frame is actually presented in the main thread. The problem
is that it was presented over and over again until the gstreamer thread

GStreamer: implement unlock() in QGstVideoRendererSink.

There are cases where blocking operations happening in the video sink
need to be unblocked, that's why GstBaseSink has an unlock() virtual
function. Since our custom video sink blocks when starting and when
rendering a frame (while waiting for the main thread to actually do
these operations), we need to implement the unlock() function in order
to unblock these operations when requested by GstBaseSink.
