- Code is simpler. We only ever reset all tracks.
- Allows the standalone media clock to be updated properly. This
allows simpler recovery for live streams in ExtractorSampleSource.
- Fixes#1285 and paves the way for a fix for #758.

- Use same constant for unknown/unset microsecond times/durations.
- Change constant values to be nowhere near the "normal" range.
- Misc cleanup.

The only change that's not re-ordering is to add a Util method
for usToMs to replace the ones in the HLS and Chunk sources.

This fixes some nuances with the initial solution. Mainly,
that the TrackStreams returned by selectTrack could not be
used safely until after endTrackSelection was invoked. It
also reduces the need for member variables to track state
between the track selection methods.

This removes the need for each SampleSource implementation to
implement 3x "if(condition) {noop}" tests (ChunkSampleSource
and SingleSampleSource were missing some of these checks).

1. SampleSource now has an explicit track selection state. This state is entered
after the source is prepared, and also by calling startTrackSelection.
2. endTrackSelection commits selection changes, and is responsible for doing the
right thing w.r.t starting/stopping/restarting load operations.
3. All sources now start or restart a load in the case of a new track selection.
This fixes a problem where a source could be advanced by repeatedly disabling
and re-enabling whilst paused. Some sources didn't restart a load in this case,
since the position was unchanged, however the downstream renderer would then
consume media up to the first keyframe in order to render something. Hence
each disable/re-enable would advance by a keyframe.
4. This change will enable a subsequent change where we'll discard media for
non-selected tracks earlier than we do currently (i.e. we'll hook the extractor
to a dummy track output, so the samples will never be written to a rolling
buffer). This will enable a further subsequent change where buffer contributions
are per-renderer rather than per-source.

This change replaces TrackGroup[] with TrackGroupArray. This is
to allow equality based hashCode and equals implementations.

The TrackSelector API will look like:
TrackSelection[] selectTrack(
TrackRenderer[] renderers, TrackGroup[] trackGroups);
In this CL:
- SampleSources return TrackGroup[], so that the result can be easily
passed to the selector.
- TrackStream gets its own file to sit alongside other Track* classes.
- A TrackSelection object is introduced to encapsulate group and track
indices.

Notes:
1. The logic in ExoPlayerImplInternal is very temporary, until we
have proper TrackSelector implementations. Ignore the fact that
it's crazy and has loads of nesting.
2. This change removes all capabilities checking. TrackRenderer
implementations will be updated to perform these checks in a
subsequent CL.
