If there is only one track, we can assume that both boxes refer to the same track
even if the track indices don't match.

MediaDrm.provideXResponse methods only accept the response
corresponding to the most recent MediaDrm.getXRequest call.
Previously, our code allowed the following incorrect call
sequence:

a = getKeyRequest
b = getKeyRequest
provideKeyResponse(responseFor(a));

This would occur in the edge case of a second key request
being triggered whilst the first was still in flight. The
provideKeyResponse call would then fail.

This change fixes the problem by treating responseFor(a)
as stale. Note that a slightly better fix would be to
defer calling getKeyRequest the second time until after
processing the response corresponding to the first one,
however this is significantly harder to implement, and is
probably not worth it for what should be an edge case.

Both boxes should contain the same list of track indices. However, if only one
track index in each list does not match, we can just assume that these belong
together.

It's quite hard to find the defaults currently. Placing them
on each variable makes them easier to find.

Currently we immediately stop searching after we found one video and one
audio track. This change adds some leeway to detect additional tracks.

Add withSkippedAd method to AdPlaybackState. Currently it is only possible to skip entire ad groups but not individual ads within a given ad group.

When switching from Stack to ArrayDeque, calls to add() need to be replaced by
calls to push() because ArrayDeque treats the first element in the list as the
top of the stack.

String.split() has counterintuitive default behavior; see
https://github.com/google/error-prone/blob/master/docs/bugpattern/StringSplitter.md.
I've switched usages to pass limit = -1 argument, which means empty elements are
no longer removed from the end of the returned array.
