feat!: Rewrite build system and third-party dependencies (#1310)
This work was done over ~80 individual commits in the `cmake` branch,
which are now being merged back into `main`. As a roll-up commit, it is
too big to be reviewable, but each change was reviewed individually in
context of the `cmake` branch. After this, the `cmake` branch will be
renamed `cmake-porting-history` and preserved.

Joey Parrish ac125564b9 build: Fix pylint 2.10 issues, use python3 where possible
The newest pylint release complained about several issues that the
older release did not.  This resolves those issues:

 - removes unneeded "u" prefix from strings
 - adds "encoding" parameter for all open() calls
 - because "encoding" is a python3-only parameter, use python3 in all
   the scripts that we control

Unfortunately, python2 is required for any scripts that import modules
from the ancient Chromium build system we're using (referenced by
DEPS), as well as kokoro scripts.

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.

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 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.

Jacob Trimble 665e784cbd Move PSSH generation to EncryptionHandler.
The KeySource now only handles fetching the keys and loading any PSSH
info from the license; it will not handle generating new PSSH info
based on the config.

This will allow the PSSH generation to access to the full
EncryptionConfig so we can add additional options to it.

provide a better, text-based diff of the MP4 files.  This makes looking

Added Dolby Vision backward compatible signalling, i.e. for Dolby Vision
profile 8, both base codec without Dolby Vision and HDR codec with Dolby
Vision are signalled.

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

KongQun Yang 0342adb132 Fix possible packager hangs when reading mp4 from FIFO
For MP4 files, mp4 parser tries to open and read the same file again
to handle trailing MOOV box.

Open FIFO again may result in packager hang.

Update the code to only attempt to load MOOV for local regular files,
as FIFO and remote files are unseekable anyway.
