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.

Jacob Trimble 51fe84f9d5 Provide better diffs for MP4 failures.
If the user has the GPAC MP4 tools installed, this will use that to
provide a better, text-based diff of the MP4 files.  This makes looking
at test failures much better than just "binary files differ".

KongQun Yang b900565a0f Support Dolby Vision backward compatible profiles
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.

This is achieved by using a new MuxerListener implementation
MultiCodecMuxerListener, which wraps multiple child MuxerListeners and
is able to delegate to the child MuxerListeners based on the codecs in
the stream.

Closes #341.

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.

Aaron Vaage b9dee56294 Rebuild Text WebVtt to MP4 WebVtt
The previous text to mp4 webvtt pipeline was incomplete. It
did not insert ad cues and it could only insert a segment
after a sample ended.

Now the pipeline supports ad cue insert and segment insertion
mid text sample. This required the pipeline to use the text
chunker (to split samples and insert segments) and required
a major overhaul of the text to mp4 converter.

Before the converter came before the chunker. This meant that
the converter only expected to see stream info and text samples.
Moving the converter after the cue aligner and chunker means
that the convert had to be aware of segments and cues.

The general approach is the same, however the converter will
convert the samples per-segment as the chunker will introduce
duplicate samples if a sample spans across segments.
