sure all events are processed before terminating the worker.
- Correctly cache the preview size even when it's an invalid one.

Allow the user to specify the viewfinder resolution instead of guessing

Guessing badly prevents the camerabin pipeline from loading at all and
the fallbacks used are not representive of the capabilities of most
cameras. So either stay out of the process and let gstreamer negotiate
a resolution if it can, or use a resolution supplied through the viewfinder
settings control by someone hopefully better informed.

Remove workaround for resolved gstreamer bug.

Reloading the capture pipeline before recording is unnecessary and
introduces a big pause. Don't do it.

https://bugzilla.gnome.org/show_bug.cgi?id=649832 was resolved in gstreamer 0.10.23

Fix writing orientation and date exif tags in camerabin.

Orientation tags need to be transformed from the string tag returned
by gstreamer to the orientation in degrees.  Date tags need to be
inserted with gst_date_time_new_local_time.  Finally setting a tag
value shouldn't clear all other tags.

Fix incorrect/missing application of recording settings in camerabin.

Don't set profiles if no settings are specified.
Apply all settings before starting a pipeline as the mode can switch
without being restarted and incompatible video recording settings can
prevent the pipeline starting even in image capture mode.
Set audio encoding settings and encoder profiles if they are supplied.

Android: optimized NV21 top ARGB32 conversion.

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).

Android: fixed video rendering with multiple media players.

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.
