This allows injection of custom implementations and configuration of
DefaultHlsPlaylistTracker without modifying the HlsMediaSource interface.

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.

If a MediaPeriod uses a Loadable, then there are typically
reference chains of the form:

LoadingThread[GCroot]->Loadable->MediaPeriod->Player

Where the player is the MediaPeriod callback. When the
player is released, this reference chain prevents the
player from being GC'd until Loadable cancellation
completes, which may not always be fast. This in turn
will typically prevent the application's activity from
being GC'd, since it'll normally be registered as a
listener on the player (directly or indirectly via
something like a view).

This change mitigates the issue by removing references
that the MediaPeriod holds back to the player. The
MediaPeriod will still not be eligible for GC, but the
player and application activity will be, which in most
cases will be most of the leak (in terms of size).

This helps to use the AnalyticsCollector without SimpleExoPlayer. Currently,
that may be problematic, if the contructor needs the player, but in order to
create the player, one already needs the AnalyticsCollector as a listener for
the renderers.

This simplifies Loadable implementations, and also removes the
possibility of an incorrect Loadable implementation causing the
wrong Loader.Callback method being called (perviously, for the
correct method to be called, we relied on isLoadCanceled being
implemented correctly).

There is the small (but unlikely) chance that the uids clash because the
Objects have the same hash code.

The bug here was that we'd create a VideoFrameReleaseTimeHelper
using whatever context DefaultRenderersFactory has, and it would
then hold a reference to that context via DisplayManager. A leak
could then occur if the player outlived the life of the context
used to create it (which would be strange/unusual, but not
impossible).

As highlighted by the ref'd issue, we can end up with
memory leaks if Loadable.load implementations take a long
time to return upon cancelation. This change cuts off one
of the two problematic reference chains.

This doesn't do much about the ref'd issue, since there's
a second reference chain that's much harder to deal with:
Thread->LoadTask->loadable. But since it's easy just to
cut this one off, I figure it makes sense to do so.

This makes the requirement that all calls are made on one thread more
explicit and also mentions this in the Getting Started guide.

I think it was just wrong that it was package private before, since
it resulted in our public API referencing something that's not part
of the public API:
