- Changed startDownloads/stopDownloads back to their previous behavior
  of starting and stopping all downloads at the manager level.
- Made setManualStopReason methods for the new case of setting a manual
  stop reason or some or all downloads.
- Added plumbing to specify an initial manual stop reason when adding a
  new download, without also overwriting the manual stop reasons of all
  other preexisting downloads. Using the value is left as a TODO pending
  a bit of further cleanup that'll make it easier.

- Remove completed downloads from progress notification.
- Treat restarting as a downloading, When there are both
remove and download tasks ongoing, we prefer to show a
download notification to a remove one. A restarting task
encapsulates is basically a (remove+download) task. Given
our preference, we should treat it as a download rather
than as a removal.

Both manifest loads currently use the default retry delay although a
LoadErrorHandlingPolicy is provided to the MediaSource.

We have new strings for track role types.

- Remove NETWORK_TYPE_NOT_ROAMING and NETWORK_TYPE_METERED
  because JobScheduler doesn't support them, and they're
  probably not useful to many people (data when roaming is
  normally enabled/disabled at the OS level, and restricting
  to *only* metered networks seems niche)
- Convert network requirements proper flags
- Stop persisting requirements in DownloadIndex. The direction
  we're headed to solve the manager start/stop problem is
  going to involve state in DownloadManager determining whether
  downloads actually start, and if we're doing that then it's
  no worse to do it for this as well

We usually avoid linking to the same page. Replacing all {@link DataSpec}
with just "data spec" accordingly.

Implement Parcelable instead, which is a more intented way of
passing structured data via Intents.

Robolectric calls messages posted to the main thread immediately inline. This
will change in the upcoming release and will break tests implicitly relying
on that behavior.

Update ConcatenatingMediaSourceTest to actually wait for the posted message.

This makes sense now that DownloadAction is only for downloading,
and not also for removal.

HashMap.values does not guarantee a stable order, but our tests
assert that the order is stable. It's probably a nice property
that the order is the same as that in which downloads are added,
so this change makes the order stable, with that order.

A future change will likely improve the way this works, by
changing the internal thread "downloads" variable to have type
ArrayList<Download>, at which point the internal thread can just
pass a read-only copy of its list to the main thread whenever a
state changes.

- Fix ID being dropped when DownloadAction is serialized and
  de-serialized as it's passed to DownloadService
- Properly set DownloadAction.id when building an action from
  a DownloadState
- Make ID a required constructor argument. Else it's too easy
  to not propagate it by accident.

Remove MediaCodecSelector.DEFAULT_WITH_FALLBACK, as codec selectors
will need to be able to return a list of decoder infos even when not
using fallback in a later change. Instead signal that fallback should
be used via a renderer constructor.

Fallback is always disabled for audio.

Adding a protected method for that allows to supply a customized
TrackOutputProvider to the ExtractorWrapper used by the ContainerMediaChunk
(e.g. for logging purposes).

The alternative would be to provide a  TrackOutputProvider through the
ChunkSampleStream constructor, but the extra initialization taking place
in the ChunkSampleStream constructor would need to move somewhere else and
some methods of BaseMediaChunkOutput would need to move to the
TrackOutputProvider interface. This seems too much effort for niche
customization case.

The position should be subtracted from the total content length
retrieved from the cache in this case, both for iteration and for
filling out counters.contentLength (for the latter, note not
doing it this way is inconsistent with what happens when dataSpec
length is set to a known value).

It's a transient state whose only use is when passing a removed
download to onDownloadStateChanged. It's a bit strange to have it
as a proper state, since we end up asserting that it's an invalid
value in other places.

This change adds an explicit onDownloadRemoved, which allows
removal of the transient STATE_REMOVED, related assertions, and
uncertainty when dealing with an @State variable whether it's
necessary to handle it being STATE_REMOVED.

This is the last cl of a series of cls that will convert DownloadManager
threading model as public methods post actions on an internal thread
which then do the work.

This is part of the public API and the underscored versions
weren't intended to be used outside the library.

Also updating the external instructions to checkout the version
of libvpx that supports this macro for this particular constant.

The priority task manager only needs to listen to loading state changes and
is independent of the rest of DefaultLoadControl. This also fixes problems
where the player stops loading without consultin the LoadControl.

Necessary for implementing scheme-independant resource management.

Example: A media source needs to have ownership of a crypto resource
while samples are in buffer (but not yet in the renderer).

Most of our components that have Handler instances for calling
back to application code instantiate the Handler using Util.getLooper
in the constructor. This makes the two components that do
something else consistent with that model.
