Add standalone test application that demonstrates how to use the new
VP8 bitstream parsing library, while also allowing simple debugging/
tracing of IVF files.

Import libvpx 1.3.0 range decoder files (dboolhuff.[ch]) to implement
the VP8 utilities native interface. Likewise, copy and use the default
libvpx generated entropy probabilities tables.

* Search in current pending values first. For CBR streams we can very
easily end up having just one initial observations and then nothing
else (since the bitrate doesn't change).
* Use one group whether we are in that group *OR* if there is only
one group.
* If the group to use isn't closed (points are being accumulated in the
PCROffsetCurrent), use the latest data available for calculation
* If in the unlikelyness that all of this *still* didn't produce more
than one data point, just return the initial offset
While the calculation done in these macros will work with 64bit
integers, they will fail if working with 32bit integers.
Force the scaling up to solve that.
This amazingly didn't introduce major issues up to now, but resulted
in bogus values in debug logs.
Doing a hard flush on the packetizer will drop all observations, which
will eventually break push-based seeking (with BYTES segment) since
we won't know where to seek to anymore (new data would always be
considered as the beginning of the stream).
"(NSApplication *)sharedApplication This method also makes a connection
to the window server and completes other initialization"
The implicit thing which is not mentioned is that it required
to be called in the main thread.
Fix a regression introduces by 82b7c915bb
When using with gst-launch, it was not possible to click on the close
cross of the window anymore which is a bit anoying and also because
it's was possible before.
Prior to this commit the GstGLContextCocoaClass was initialized
in the main thread because gst_gl_context_new was called in the
state change function from going from ready to paused.
From this commit this call is done from the streaming thread.
So that the call to [NSApplication sharedApplication];
was not done in the main thread anymore.
We now ensure that by assuming there is a GMainLoop running.
It's for debugging purpose so that's ok to do that. Also
note we already do this assumtion to run app itereations.
The regression had no consequence on the cocoa/videooverlay example
(that should be moved from gst-plugins-gl to -bad) because the
application is responsible for that necessary call.
