This sets the groundwork for more generic text cues by having a more
generic object for the settings and the body. This also changes the
TextSample to be immutable and accepts the fields in the constructor
instead of using setters.

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.

Renamed all the files called "webvtt_output_handler*" to
"webvtt_text_output_handler*" to better reflect the class name
in them.

Before, the webvtt output handler was written so that it could
share code between a segmented and non-segmented handler. As
we are not worried about that right now, this change simplifies
the handler to just be about segmented output.

The Cue class was from a previous WebVTT implementation and
is not used in the current implementation. It was missed when the
other classes were removed. This change removes it.

Created a media handler to come after parsers that will handle filling
in gaps between text samples. The padder takes a min duration, and if
the samples do not cover the min duration when flushed, one last empty
sample will be injected so that the samples will go up to the min duration.

Move the webvtt segmenter to the chunking directory so that it
can be converted to a general purpose text chunker.

Now that we have the end-to-end tests, we no longer need the webvtt pipeline
tests to verify that it is working.

Connected the WebVtt Pipeline together to test that the parser,
segmenter, and output all work together as expected.

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.

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.

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.

Created a handler called OriginHandler that can be used by the Job class
(previously called RemuxJob). Origin handlers represent the start (or
origin) of a pipeline (chain of handlers).

Moved all the timestamp parsing code into its own class with its
own unit tests. This is to make testing easier.

On Linux the generated ninja files use path/libbase.a as target name.
In the Mac ninja file the target is just libbase.a.
As we have two libbase.a (base/base.gyp and media/base/media_base.gyp) the linking stage fails to include both libs.
Solve by renaming media_base.gyp's base target to media_base
