These additions are useful for sources that need to track the playback position
and control playback.

Prevented readFile() setting "changed" boolean to true every time. It's set only if encryption key is set but the index file isn't encrypted.

If a period has no enabled tracks it is considered to be fully buffered, even
if its duration is unknown. This would cause the offset of the next loading
period to be set based on the unset duration of the preceding period, in turn
causing the from of the player to expose a position based on an unset value.
Only load the next period when the current one has a known duration. If a
period has no enabled tracks and an unknown duration this causes the player to
play the period indefinitely.

When CEA-608 is embedded in MP4 each packet consists of
cc_data_1 and cc_data_2 only. The marker_bits, cc_valid
and cc_type are implicit. As a result playback of CEA-608
embedded in MP4 broke when we started passing the extra
byte for the TS case (and adjusted the decoder to assume
the byte was present).
This change introduces a special mimeType for the case
where the byte is implicit (!). An alternative option
was to insert the extra byte every 2 bytes in the MP4
extractor, but this is really quite fiddly to get right.
Also made the loops in the 608/708 decoders robust against
input of the wrong length.

Encryption key in index file is read by DataInputStream.read() which may return less bytes than required. Replaced it with readFully() which should read full length of data.

Leaving disabled by default for now, but we may want to consider
enabling it by default. Note that in V1 for ExtractorSampleSource
the behaviour was equivalent to this option being enabled, since
we didn't perform capabilities checks. For DASH/SS/HLS the V1
behaviour was equivalent to this option being disabled.
The type in PlayerActivity has been changed just to make it
easier to add a line that calls setParameters.

I can't see how this would ever make a difference, but there's no
point in returning true. Either we've really reached EOS (in which
case outputStreamEnded will be true and the next drainOutputBuffer
will be turned into a no-op) or we've re-initialized the codec (in
which case there wont be anything to drain since we wont have fed
anything to the codec yet).
This change should also prevent the hypothetical NPE described in
issue #2096, although we're unsure how that NPE would occur unless
MediaCodecRenderer has been extended in an unusual way.

The simple verifications in this test may be useful for smoke testing, but the
coverage of ExoPlayerImplInternal is low. The intention is to add tests for
more complex logic in ExoPlayerImplInternal in later changes.

Select the timestamp master depending on track availability. If
a variant is being loaded, then that is the timestmap master.
Otherwise, if an audio track is being loaded, then the responsible
chunk source is the timestmap master. If no variant or audio
rendition is enabled, then a subtitle chunk source is selected as
timestamp master. This CL will become specially relevant once
ID3 PRIV timestamps are used for audio renditions.

Note that we still have null timelines in ExoPlayerImplInternal.
This is deliberate; and is likely necessary to distinguish between
the no-timeline-yet and timeline-is-empty cases (we want to try
and process a pending seek for the latter, but not the former).

- Allow extension and overriding of renderer creation.
Several developers have asked for this, so that they
can use their own renderers (typically extensions to
the core ones) without losing the ability to use
SimpleExoPlayer.
- Add option to not attempt extension renderer creation,
for efficiency.
- Align build variants for internal and external demo
apps. This is slightly unfortunate, but convergence
seems necessary for useExtensionRenderers.
- Fix DASH playback tests to use the debug video
renderer.

This issue affects ExtractorMediaSource only. We shouldn't
start loading in the case that we're prepared and have no
enabled tracks, since there's nothing that we need to load.
This was causing an assertion failure in startLoading.

Note that multi-segment fetching is only possible in the
case that segments in a representation are defined to have
the same Uri and adjacent ranges (this is very rarely true
for live streams, but is quite often true for on-demand).
In the case that merging is requested but not possible,
the implementation will request one at a time.
