Some test specific things, like adding an extra listener or adding decoder
counters are currently handled by ExoHostedTest. They can be moved to the
classes actually using them to clean up ExoHostedTest.

This also adds more flexibility to further generic clean-up in onTestFinished.

Also, reorder player setup to what ExoPlayerTestRunner is doing.

Before this change, the player state would be STATE_ENDED then
STATE_BUFFERING (when the postroll ad was marked as played) then
STATE_ENDED again.

Queueing a final content media period with start point equal to
the content duration after a postroll ensures that the player
state doesn't change to STATE_ENDED transiently.

Switch from using C.TIME_END_OF_SOURCE to C.TIME_UNSET for media
periods that should not have an end point and are not followed
by an ad.

Content media periods before postrolls have end position
C.TIME_END_OF_SOURCE. If the postroll ad loads, its content
position is set to the content duration, which should be known
at the point of loading the postroll, then a final 'empty'
content media period with start position equal to its duration
is queued. If the postroll fails to load, this empty content
media period is queued up directly after the preceding content
media period.

- Handling EVENT_PROVISION_REQUIRED is unnecessary because we handle
  it via NotProvisionedException, which was thrown on all API levels.
- Handling EVENT_KEY_EXPIRED during playback is unnecessary. All it
  does is cause an error to be thrown, but an error will be thrown
  anyway out of the MediaCodec when it tries to use the expired keys.
  It's currently a race condition where the error gets thrown from,
  where-as having it always be thrown from one place is preferable.

This paves the way to cleanly fix the first two issues
listed in [] onDisabled will null inputFormat,
but nulling of codecFormat will remain tied to the codec
being released.

ExoCastMessage contains all player management messages that the sender app can
send to the receiver app. ExoCastMessages can be serialized as JSON strings.

- Only use bitrate when comparing two tracks if their bitrates are
  actually different.
- For audio, prefer to use bitrate over selection flags.

- Improve variable naming
- In the edge case that bytes are transferred in a sample that
  has 0 elapsed time, carry the bytes forward into the next
  sample. If we don't do this then the estimate will be calculated
  as though those bytes were never transferred. In practice I
  suspect this very rarely occurs.
