It seems all Android media players share the same video buffers, which
results in textures containing frames for the wrong media player.
When getting a new frame, we now copy it into a FBO in order to avoid
that another media player overwrites the frame being shown on screen.

Now based on fixed-point arithmetic and uses pre-generated lookup tables
for YUV coefficients and RGB clamping.
The new implementation is on average 2x-3x faster than the previous one
(tested on the Samsung Galaxy S4).

We used to generate the capture preview from the video output, grabbing
the pixels of the last frame (in a FBO). This is not possible anymore,
we instead query the camera for a preview frame, which is in the NV21
format and needs to be converted to RGB.

Removed the overhead of having to create a shared OpenGL context in the GUI
thread and pre-render the frame into a FBO.
We now directly render the GL_TEXTURE_EXTERNAL_OES in the QtQuick render
thread, using an Android-specific QSGVideoNode.
We also use a callback from the render thread to create the texture from
there and not have to create a separate shared OpenGL context.

This patch includes all camera features: viewport, settings, image
capture, and video recording.
It also adds support for QAudioRecorder.
