This require a change to the update gold method as it would not
create nested directories. Instead it deletes the old directory
and copies the whole new directory over. This made the code simplier
and far-less error prone.

To make working with file names easier in packager_test.py _GetStream
the full path is not created until needed so that multiple paths can
use the same root filename.

Changed all output file names (not paths) to follow the pattern that
any qualifier (e.g. trick play) will be join the current name using '-'
but will use '_' within itself (e.g. trick_play_1).

We have an assert that ensures that the end time is greater than
the start time for any cue. However we never checked that cues
had a non-zero duration when parsing them.
We will throw away cues with a duration of zero (and print a
warning message) as they are not spec compliant.

In the video captured by Android's default camera app, meta box is written as

Prefer timestamps from Video AdaptationSets if available - this avoids
possible video playback jitters due to gaps.
presentationTimeOffset is not applied to the first period as it may in
negative dts which Chrome does not like: https://crbug.com/398141.
It is safe to apply to subsequent periods as the actual offset applied
takes Period@start into consideration:
offset = Period@start - presentationTimeOffset
The result timestamp with offset applied is close to Period@start, so
it is unlikely to result in a negative dts value.
Closes b/73899306.

Updated as many tests as we easily could. The tests that were not updated
all use live manifests or encryption that all require some "help", either
by dealing with times differing or with verifying decryption.

Created GetStream, a function used to get the stream descriptor for a
single stream. This allows for finer control over the stream compared
to the batch GetStreams.
Added "trick_play_factor" to GetStream so that the trick play factor
did not have to be added the stream descriptor value and "injected"
into the stream.

Created end-to-end tests for the segmented webvtt text in HLS. The
text stream is longer than both audio and video, so there are more
text segments than video/audio.

Created a method to diff the output dir against the golden copy
of the output dir. The goal with this is to simplify our end-to-end
test structure by removing the need to track the output files within
the test runner.
With all the golden output in one directory, this makes it easier to
setup end-to-end tests and even allows the golden files to be playable.
This should not affect the repo size too much as duplicate files will
only be stored in the git object store once.
Tests will migrate to this in separate CLs.

Changed the "live" setting in _GetStreams to be "segmented" so that it

When converting from NAL unit stream to byte stream.
The packager should not assume the parameter sets in the sample is the

Looks like Safari does not like v0 tenc box.
- Use v1 tenc box for cbcs and cens protection_scheme as required by
CENCv3 spec.
- Set crypt_byte_block and skip_byte_block to 0 for full sample
encryption cbcs and cens.

The old vtt sample data has the header as "WEBVTT FILE" which does
not reflect what the spec says it should be.
This changes it to "WEBVTT" as described in the WebVTT spec.

- Add empty lines between different types of renditions to improve
readability.
- Group variants with the same audio/text group together, as it is
where the Adaptation occurs.
- Write master playlist after writing media playlists. This makes
more sense and it is also necessary to have the bandwidth of
the last iframe playist segment correctly computed.
- For fMP4, I-Frame segment must include the 'moof' header.
- Fix a problem that hls_iframe_playlist_name is not passed to
MuxerListenerFactory.

Instead of always tracking segments with an index, this change makes a struct
that will act as the segment and track which segments are in it. Each
segment will store all the samples in the order they were given, it will
avoid any sorting.

If no hls group name is given, we would default to "audio" but as
we are working to support text, this won't make sense to see
GROUP="audio" on a text stream.
Instead default to "default-audio-group" for audio streams. A specific
text default will be added later.

In the master play list, use a class called variant to build
the video tags.
The variant list will always have one entry. In the case that there
are no audio streams, the variant list will have a null entry.
