SDK / exoplayer

[Problem]
There are 3 services / modes transported on line 21:
- Captioning
- TEXT (generally not program related)
- XDS (eXtended Data Services)

Bytes belonging to the unsupported modes are interleaved with the
bytes of the captioning mode.
See Chapter 7, Chapter 8.5 and Chapter 8.6 of the CEA608 Standard for
more details.

[Solution]
Drop all bytes belonging to unsupported modes.

[Test]
- All streams containing only captioning services should not be influenced
- Test all 4 CEA 608 channels with live over-the-air content and
using all available TEXT and XDS streams.

There are no logic changes here. It's just moving code around and removing
the "internal" part of names where no longer required.

We currently toggle the view in onTouchEvent ACTION_DOWN which is non-standard
and causes problems when used in a ViewGroup intercepting touch events.

Switch to standard Android click handling instead which is also what most
other player apps are doing.

Also add some unit tests for codecs strings parsing.

Disabling stack trackes currently logs messages twice, once with and once
without stack trace.

The AndroidX bundled version (0.42) lags behind the most up-to-date public
release (0.44) making it more difficult to stay close to the actual head
revision which is used internally.

This ensures we keep the loading period in sync with the the playing period in
PlybackInfo, when the latter changes to something new.

Also re-enable two of them, although note that the fix here is
not related to the flakiness that caused them to be disabled.
I'm re-enabling them since much has changed in DownloadManager,
and the hope is that these tests are no longer flaky.

Experiments show this is beneficial for rebuffers with only minor impact
on battery usage.

Configurations which explicitly set a minimum buffer duration are unaffected.

Before this change we'd release the audio track and create a new one as soon
as audio processors had drained when reconfiguring.

Fix this behavior by stop()ing the AudioTrack to play out all written data.

- We had buildAddRequest and sendNewDownload. Converged to
  buildAddDownload and sendAddDownload.
- Also fixed a few more inconsistencies, and brought the
  action constants into line as well.

- Listener based reporting of progress allows the content length
  to be persisted into the download index (and notified via a
  download state change) as soon as it's available.
- Moved contentLength back into Download proper. It should only
  ever change once, so I'm not sure it belongs in the mutable part
  of Download.
- Made a DownloadProgress class, for naming sanity.
