Previously, writeAllocationNode was not advanced to the
terminating node when finishing writing sample data that
fills exactly up to the end of the current write node.
This wasn't actually broken, but is confusing because it
causes edge cases where the start/read references could
temporarily refer the node after the current write node.
This change advances the write reference in this case,
removing this confusion and bringing the implementation
in line with what the design doc says happens.

Also making some simplification and consistency changes.

This will allow us to maintain a reference to the middle
of the queue, which is necessary to efficiently support
decoupling the read position from the start of the buffer.

(Fixing GitHub issue #2699)

Added controllerAutoShow parameter to decide whether playback controls are
shown automatically. Default is true. Can be overwritten in the XML with
auto_show=false or via SimpleExoPlayerView.setControllerAutoShow(false).

Also inverted the logic of maybeShowControllers and showController.
SimpleExoPlayerView.(show/hide)Controller and PlaybackControlView.(show/hide)
now unconditionally do what they say to allow manual operation.
SimpleExoPlayerView.maybeShowController is used internally to automatically
show playback controls.

(Preparation for GitHub issue #1706)

AbstractConcatenatedTimeline repeatly calls methods of its implementation to
query a specific child timeline. This may be inefficient if the implementation
repeatly executes the same code to find the timeline.

Changed the class such that it now queries all information at once using a meta
data class. As all methods need at least two of four variables anyway, this
doesn't generate unnecessary overhead.

Also generified the UID for the child indices to allow new implementations to
use some other UID besides the index.

The same effect can be achieved by checking the isLoading variable of ExoPlayerImplInternal
because this variable is in almost all cases set simultaneously with loadingMediaPeriodHolder.needsContinueLoading.

continueLoading may be called during preparation, but this is not
handled correctly in the case where a deferred period doesn't
have a source yet.

Separate MediaPeriodHolder.index and MediaPeriodHolder.periodIndex, so that the
latter is always a period index (which may repeat or jump) whereas the holder
index increases by one each time an item is added to the period holder queue.

Currently, media is discarded from DefaultTrackOutput
and SampleMetadataQueue as soon as it's been read. In
upcoming changes we'll decouple discard and read. This
will make it possible to retain already-read media in
these buffer classes, and allow the read position to
be moved backward as far as media is retained. This is
important for fixing an edge case around 608/EMSG
tracks, and could also underpin future features like
allowing retaining of X-seconds past media in the
buffer.

This change renames some variables and methods to
prepare for the upcoming changes. read/write indices
are renamed to start/end. The upcoming changes will
add a read index that's between the two. isEmpty is
inverted and renamed to hasNextSample, since it will
be possible to not have a next sample (because the
read index == end index) but for the buffer to not
be empty (because start index < read index).

It's pretty big as an inner class, and is going to get a
little more complicated. I think it makes sense to be
able to consider it in isolation.

This prevents strange behaviors for streams that changes the track declaration
order in the PMT.

NOTE: This should not change ANY behavior other than the one described above.

When updating track selection, we should only revert back from ideal
track selection to current track selection if the currently selected
track is not black-listed.

1. Remove tools:replace in manifest files. This attribute is only needed to establish priority when two manifests are merged and have the same attribute with different values.
As this is not happening here, the attributes can be removed.

2. Some BUILD files also define a deprecated manifest merge strategy different from the android default merge strategy. For consistency these are set to "android'.
