Originally the create and dispatch of stream data in the cue
alignment tests were separate to improve readability. The idea was
to separate building each stream and dispatching the streams muxed
together would make it easier to understand the streams.
However, coming back to the code, this did not hold up as it took just as
long to understand the code. So merging the two together allows for the
code to be more concise.

In the media handler there is an example of what a one-to-many media
handler would be. It used the trick play handler as an example, but that
handler is now a one-to-one media handler. Changed the example to use the
replicator media handler.

We have adopted some new standards for how we are writing the media
unit tests. This change goes through the trick play tests and
updates them to be more inline with how we are doing new media
tests.
This include using "_" for parameters that are not the focus of the
tests (used in the EXPECT calls).
This includes wrapping Dispatch calls so that the test bodies can
be more readable.

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.

In the cue aligner, we assumed that all text will be in milliseconds.
This was the last place with that assumption. This change removes that
assumption and uses the stream info's time scale.
Issue #399
Change-Id: Ie21bf27148e020bd85111dcace0bbdff3419c1ac
Before, the text chunker would assume that all text streams were in
MS, which is not a safe assumption to make.
This changes it to take the time scale from StreamInfo and work
natively with scaled time units.
This required updating the tests. While doing so the tests were
rewritten with the goal to make them easier to read.

Text Samples with no payload should be ignored, so this adds a
test to check that samples with no payload get treated the
same as a gap.
As long as this case is true, using gaps in our other tests should
functionally be the same as using samples with no payload.
Change-Id: Ic16b240c43eda2514b537a2d938d4135638adc4e
Before we used the sample payload for each text sample as we were
focusing on the times rather than the contents.
As we look to add tests that rely on specific sample payloads, we
need to change the tests to explicitly set the payload for each
sample.

EPT (earliest presentation time) may be adjusted not to be lower than

In our text to mp4 tests, we were only checking if the times on
the samples lined-up with what we were expecting.
We want to check that text sample contents (ids, settings, and
payloads) were correctly merged into a single media sample. To
verify this, we now check if the sample ids appear in the
media sample.

In our text to mp4 tests, we used the same sample id for each sample,
this changes it so that each sample (within a single test) has a
unique id.
This is done in preparation to look for the ids in the created
media samples.

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.

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.
