style: Use angle-brackets for all internal headers (#1271)
This feeds into efforts to create a working install target.

The order of headers is still funky, and was "fixed" by clang-format,
but in a way that doesn't exactly align with the style guide. Further
cleanup of header order is coming in a follow-up PR.

Joey Parrish cfbe5c08c2 cleanup: Convert all time parameters to signed
This converts all time parameters to signed, finishing a cleanup that
was started in 2018 in b4256bf0.  This changes the type of:
  - timestamps
    - PTS specifically
  - timestamp offsets
  - timescales
  - durations

This excludes:
  - MP4 box definitions
  - DTS specifically

This is meant to address signed/unsigned conversion issues on arm64
that caused some test cases to fail.

Jacob Trimble 10e71680a1 Parse WebVTT regions and styles.
This adds more generic settings for regions and CSS styles.  These are
global settings, so they go on the StreamInfo object.

Jacob Trimble 1f21cc78cd Add style support for cue fragments.
Now text cues are composed of nested fragments that can be individually
styled.  This allows portions of the cue to be bold, etc.  The
WebVTT parser doesn't parse the inputs, but the original tags are
preserved in WebVTT output.  The WebVTT output will add tags if the
style elements are present in the cue object.

Jacob Trimble 414f4589c8 Parse TextSettings from WebVTT.
Now the Cue settings are a generic object that is parsed in WebVTT.
This will allow setting the settings in different parsers without having
to use WebVTT-specifics.

Jacob Trimble b2220eb0c6 Add text fragment and setting types.
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.

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.

Joey Parrish 962baf0286 Fix reading WebVTT from a pipe
Opening a named pipe can block until both ends are open, and we cannot
control when the other end will be open.  Ideally, we would always
open files in a thread so that Packager can be used with piped inputs
from naive applications without a potential deadlock.

This change will defer opening WebVTT files until the parser Run()
method is called from a thread.  This way, WebVTT files being sent in
from a pipe will never be able to block the main thread.

Previously, files were opened on the main thread before calling the
parser constructor, passing the open file to the constructor as an
argument.  I also tried doing it in the parser's InitializeInternal()
method, but that is also called from the main thread.

KongQun Yang f49b89280c Support STYLE and REGION in WebVTT
Note that STYLE and REGION are not supported in mp4 container due to
spec limitation as 14496-30:2014 does not specify a way to signal
styles/regions inside mp4.

Closes #344.

KongQun Yang 308b92d16e [WebVTT] support cues without payload
WebVTT cues without payload may not carry meaningful information, but it
is allowed by WebVTT specification [1]. It could also be useful
sometimes, e.g. to signal the time progression in live case.

Fixes #433.

Aaron Vaage fbc4952e21 Updated StreamData Matchers to Use Matchers
Updated all the stream data matcher we use in our unit tests
to allow us to use matchers in them. We are now able to use "_"
to ignore specific parameters.

With this we were able to replace the different version of
matchers for each stream data type with a single instance for
each type.

Includes updates to printing strings to the listener. Strings
now go through a "pretty" function to help make it easier to
read them in the output.

Aaron Vaage df6661b93d Fixed Incorrect BOM used in WEBVTT Header
When originally implementing the webvtt parser, there was a
misunderstanding in what the BOM was suppose to be
(https://en.wikipedia.org/wiki/Byte_order_mark). This corrects the
misunderstanding.

Aaron Vaage 56c2f227ff Skip Style and Region Blocks
To ensure that we can parse content with style and region blocks,
this change updates the parser to skip those blocks so that we
can still parse the cues from a file.

Full style and region support will be added later this year.

Aaron Vaage 7dd80884c3 WebVtt Ignore Zero Duration Cues
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.

Took the WebVTT Media Parser and created the WebVTT Parser

will later be passed to another Media Handler that takes in
cues and chunks them.
