The start code for H.262 codec-specific data may be across a packet boundary.
Before this change the offset passed to CsdBuffer.onData may have been before
the start point of the data in the newData buffer.

After this change, start codes are added directly to the CSD buffer when it's
filling and any start code bytes added by onData (at the end of a packet) are
discarded.

This was a bug as the data set should contain sample data for all available
tracks. Also added a unit test.

We do this in the dynamic case, and I think we've seen
a few GitHub issues where developers do this and don't
understand what they've done wrong (because the failure
comes later).

Also don't detach any attached player in release() to prevent a possible
NullPointerException if ImaAdsLoader.release() runs first, then the MediaSource
is released and detaches the player. This is safe because if the loader was
attached it's guaranteed to be detached.

The canStop method gets called every second in a seperate thread until the
test can be stopped. Replacing it with blockUntilEnded forwards the
responsibility to stop to the test itself which has better control over the
stop condition.

Currently the ExoPlayerWrapper is used to run tests using an ExoPlayer
implementation. Some properties of the test are set in the constructor, some
are set by overloading the class, others are hard-coded in the
ExoPlayerWrapper class, and a mechanism similar to the existing ActionSchedule
is missing.

This change does the following:
 1. Renames ExoPlayerWrapper to ExoPlayerTestRunner as it better reflects
    its purpose.
 2. Adds an internal Builder to easily set-up the test in a coherent way. This
    allows to only set necessary test components while using defaults for the rest.
 3. Integrate ActionSchedule.
 4. Apply the new structure to the existing tests currently using ExoPlayerWrapper.

The new actions are: prepare source, set repeat mode, wait for timeline
change, wait for position discontinuity, execute Runnable.

Moreover, this change removes the restriction of using a SimpleExoPlayer to
allow ActionSchedule to be used in other scenarios.

Prepend sequence headers to the next frame, instead of appending them to
the previous frame. Tested decoders like FFMPEG and Google's
Android/MPEG2 expects to read the sequence headers before the first
frame they apply to. When sequence headers are appended to the previous
frame, these are ignored and this leads to incorrect decoding.

There's no way to represent a beta in our integer versioning
scheme. I propose we just set it the same for all betas + the
stable release. The versioning for the demo app isn't that
important, so I've just put it directly to 2.5.0 as well.
