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).

Open was not calling through to upstream.open. This was not problematic for
reading, because DataSourceInputStream.read would open the upstream if it's
not open already. It was however a problem for calling getUri() between
calling open and the first call to read, which would end up calling
upstream.getUri() on the not-yet-opened upstream.

Also only listen to requirements when actually necessary, else we can
put the service into the foreground when it needn't be there.

This type of flicker was visible (at least on my S8) whenever starting
the demo app process (from being properly killed) when other notifications
(e.g. completed download notification) was present.

This change passes whether the service was started as foreground through
the intent, and only applies the show-notification-on-stop hack if it
was. It's only necessary to start as foreground if your app is not already
in the foreground, so it's not necessary to do this from activity/ui
components.

If an app wants to reconcile its own state with that of a DownloadManager,
it's helpful to know when the DownloadManager has finished restoring any
previously persisted tasks.

Also suppress initial "state changed to paused" listener invocations for
tasks that are immediately started.

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.

This may be preferable for using custom binary data,
and it's still easy to store Strings if needed.

The old event listener on AdsMediaSource is deprecated, in favor of
reporting in the normal way (via MediaSourceEventListener).

Add AdLoadException with information on what ad/ads failed to load.

Upstream components may incorrectly clear the interrupted flag and not
propagate an exception when the caching thread is interrupted due to
cancellation. Pass a settable flag down to CacheUtil.cache and check it
frequently so it's not necessary to rely on the interrupted flag.

This avoids the interrupted flag being lost if the exception
is handled as an IOException.
