Joey Parrish 56e227267c Fix python linter errors and add linter checks to CI
Internal CI systems and the new GitHub CI system were out of sync,
with the external system not doing any linting.  Further, the internal
system was using an internal-only linter for Python.

This creates a script for Python linting based on the open-source
pylint tool, checks in the Google Style Guide's pylintrc file, creates
a custom action for linting and adds it to the existing workflows,
fixes pre-existing linter errors in Python scripts, and updates pylint
overrides.

Joey Parrish a2e07a901e Refactor actions and workflows
It turns out that workflows were the wrong way to abstract reusable
pieces of work.  This turns common steps into custom actions (build
docs, build packager, test packager) which can be used as encapsulated
steps in multiple workflows.

This is a much more natural way to avoid duplication compared to the
previous approach of triggering one workflow from another.  This also
has the benefit of all of the steps of a release being represented on
GitHub as a single workflow, making it easier to understand what is
happening and what event triggered those steps.

Jacob Trimble a93eeca5db Add TTML-in-MP4 output support.
This changes the default MP4 output to use TTML and adds a way to
choose which one is used.  This is done with 'format=ttml+mp4' or
'format=vtt+mp4'.

This also fixes the boxes output in WebVTT in MP4.

Jacob Trimble 4766654b4d Add TTML text output.
This only supports TTML output; meaning the user can convert WebVTT
into TTML, but not the other way around.  This will be useful for
DVB-sub subtitles that would be better supported within TTML.

This only adds text-based output; a follow-up will add MP4 support.

Jacob Trimble f4c07b9ce0 Work around non-deterministic tests.
We currently have a bug about non-deterministic output in the MPD
generator.  This works around that bug by optionally doing everything
in a single thread.  This allows us to run manifest comparisons without
making the major changes needed to add that feature.

Jacob Trimble 56908a83a7 Convert text WebVTT output to muxer.
Now text-based WebVTT also uses the generic media pipeline.  This
converts the WebVttTextOutputHandler to a WebVttMuxer to be more
consistent with the other muxer types.

This also allows choosing between single-segment text and multi-segment.
Before, we would generate both and use single-segment for DASH and
multi-segment for HLS; but now you can choose between either and either
are supported in both DASH and HLS.

Jacob Trimble 2909ca0c77 Handle segmented text same as audio/video.
Now the same pipeline for handling the audio/videos streams will handle
the segmented text streams too.  This doesn't apply to the text output,
only to the MP4 variants.  This also fixes a bug where we added the
X-TIMESTAMP-MAP tag even when there wasn't TS streams; this doesn't
otherwise change the behavior around that tag.

Jacob Trimble 9babfb883b Fix segmented WebVTT test.
The test added in the previous CL was broken due to a rebase on another

test.  This wasn't caught since I didn't rebase and re-run the tests
before merging.

Jacob Trimble e3bc85f12d Make WebVttParser a MediaParser.
This changes it from an OriginHandler to a MediaParser and moves the
handling of it to the Demuxer.  This will allow more generic handling
of text by giving it the same abstractions as video/audio handling.

Added Dolby Vision backward compatible signalling, i.e. for Dolby Vision

MultiCodecMuxerListener, which wraps multiple child MuxerListeners and
is able to delegate to the child MuxerListeners based on the codecs in
the stream.
