Until now, the streams were released and re-enabled for each type of stream
(primary, event, embedded) in that order. That leads to problems when replacing
streams from one type to another (for example embedded to primary).
This change restructures the track selection to:
1. Release and reset all streams that need to be released or replaced.
1(a). Including embedded orphan streams.
2. Select new streams.

This url is readily available when creating media source events (from the
data source) but so far not published to external listeners. This change
adds a new field to LoadEventInfo which corresponds to DataSource.getUri().

Both values are helpful for event reporting, but are only available while
the data source is open. Similar to bytesLoaded, they need to be reported

Using new Handler(this) in a constructor potentially leaks an uninitialized
object. This is mostly not a problem because we don't use the Handler within
the constructor. Added a Util method to keep the warning suppression local.

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 is useful to get hold of the manifest to then obtain DRM init data in
the download flow for protected content (without having to download the
manifest again).

Also convert them to exposing periods and track groups, like
regular MediaSources do. This gets us much closer to being
able to use standard track selection components during offline
initialization. The helper is responsible for reverse mapping
selected tracks onto physical streams when generating the
download action. This is trivial except for the HLS case, which
is a TODO for now.

- Made parts of DownloadActions public that were previously hidden.
This is necessary so that when an app is listening to the
DownloadManager, it can tell something about the tasks.
- Simplified DownloadActivity some more. The helpers may migrate
into their corresponding modules at some point, and also be
converted to return structured TrackGroupArrays rather than a
flat list of Formats.

A single master version prevents app developers from providing
custom download functionality (because they can't increment the
version). It's also error prone to expect someone modifying the
DASH action to remember to update the ActionFile master version.

This was adding a lot of code, and the multiple use cases
for Downloader was pretty confusing (in particular the
ordering of method calls was unclear). It's also not
performant (e.g. it requires loading/parsing manifest(s)
and initialization segments from disk).
In practice I think apps will need to keep a record of
what's offlined in their app's database (or equivalent),
which they can update by registering as a listener on
DownloadManager. This will be done for the demo app in
a subsequent change.

- When calculating the downloaded percentage in DASH, there was no
way to disambiguate between 0 of 0 segments being downloaded because
there are no cached indexes (i.e. 0% downloaded) and 0 of 0 segments
being downloaded because the index defines 0 segments (i.e. 100%
downloaded).
- Also replace use of NaN with a named constant.

When we play downloaded content, we rely on the manifest filters
to produce a manifest that contains only the content that was
downloaded. It makes sense just to use the same filters during
download too, so we don't have to worry about any implementation
differences.

ProgressiveDownloader never implemented this properly, and we
don't use it in DownloadManager/DownloadService, both of which
use a polling model. A polling model is also what's used elsewhere,
for example to query the current playback position.
This is effectively doing the TODO in ProgressiveDownloader.

This field (formerly "id") is almost impossible to use so far. Having setters
in the factories allows to specify custom tags for all media sources.
Also added a ExoPlayer.getCurrentTag() method to retrieve the tag of the

We currently refresh repeatedly in this case. According to the
DASH spec omitting minUpdatePeriod indicates that the manifest
does not change, and therefore we should not refresh. I think
it might be valid to omit minUpdatePeriod in a dynamic manifest
if relying exclusively on EMSGs to trigger manifest refresh.

This change enables feeding decoders from the closest sync frame
before a specified seek position, where-as previously we'd
always feed decoders from the start of the chunk. This avoids
decoding and discarding many audio samples during each seek. The
same benefit also applies to video chunks containing more than
one key-frame.

This adds callbacks for creating, releasing, and starting to read from media
periods.
Such events allow listeners to keep a list of active media periods. This is
useful to determine when no further events for a certain media period are
expected. It also allows listeners to associate renderer events unambigiously
with a reading media period.
