This change introduces handlers to output WebVtt text files. There is
only one output but there is a common base to support others.
WebVttOutputHandler which handles all communication with other handlers
and WebVttSegmentedOutputHandler is responsible for listening for events
and choosing when and where to write cues and headers.

Instead of having multiple char readers, one for strings and
one for files, just have one for files and use memory files
when testing.

To better align with the Chunking Handler, the Text Segmenter
now outputs the SegmentInfo at the end of the segment rather
than the start.

Move AdaptationSet related functions to the new Period class, which
maps to <Period> element and provides methods to add AdaptationSets.

Clean up DashIopMpdNotifier to make it easier to add Period class.
- Consolidate protected AdaptationSet grouping related logic to the
internal ProtectedAdaptationSetMap class
- Clean up AdaptationSet creation logic and updating logic

Implemented a MediaHandler that takes text samples and creates
media samples. The data in each media sample is the MP4 box for
non-overlapping cues.
As per WebVtt in Mp4, all cues must be non-overlapping. This handler
takes care of grouping and dividing cues.

This change creates the webvtt segmenter which will be used for
segmented text webvtt for HLS. It takes a stream of text samples
and injects segment info messages based on the segment duration.
It is possible for samples to extend between segments, if so the
sample will appear twice (once in each segment).

Took the WebVTT Media Parser and created the WebVTT Parser
that will take in a file and output a stream of cues that
will later be passed to another Media Handler that takes in
cues and chunks them.

Moved from mpd_unittest.cc to representation_unittest.cc.
Also removed unused test data files in packager/mpd/test/data.

Move AdaptationSet related tests to adaptation_set_unittest.cc and
Representation related tests to representation_unittest.cc.

Added gMock matchers for matching xmlNodePtr and its attributes.
Clean up mpd_unittests to make it easier to separate adaptation set
tests and representation tests.

Moved all code dealing with jobs into its own class so that the
packager code does not need to worry about initializing, running,
or stopping jobs.

As specified in HLS spec (https://tools.ietf.org/html/rfc8216):
All audio EXT-X-MEDIA tags SHOULD have a CHANNELS attribute. If a
Master Playlist contains two Renditions encoded with the same
codec but a different number of channels, then the CHANNELS
attribute is REQUIRED; otherwise, it is OPTIONAL.

Seeing some failures on some platforms when compiled with clang
disabled:
GYP_DEFINES="clang=0" gclient runhooks
Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
direct control: dangling-else, deprecated-declarations,
unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
all linux distributions.

1. Expect the time elapsed to be greater than kTimeout instead of
approximately equal to kTimeout if there is a "wait";
2. Expect the time elapsed to be smaller than kTimeout instead of
approximately equal to 0 if there is no "wait".
Also rename a variable in packager.cc to better reflect what it is.

It aligns with what a lot of other apps are doing, e.g. tsplay.
Also added notes in docker to adjust network setting if wants to use
multicast in docker container.

The error is logged only once to avoid log spamming.
Added definitions for the unsupported stream types for easy look up.

This patch also fixes a bug which was introduced in
https://widevine-internal-review.googlesource.com/c/packager/+/38040
where it was inconsistently assumed that AdCueGenerator would be MIMO
while connecting with other handlers and at the same time it was assumed
SISO in the AdCueGenerator class. Now we assume SISO everywhere.

The spec allows having more than one 'mdat' boxes even if it is not
used.
