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.

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.

They will result in empty DASH representations, which is not spec
compliant.
For text, if the cue is before the max end time, it will still be
dispatched as the text samples intercepted by the cue can be split into
two at the cue point.

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.

Reduce which variables we check in the cue alignment tests by replacing
the less important variables with "_".

Added the key frame field to the IsMediaSample mather. All
tests that do not care about a sample being a keyframe (or not)
have been updated to use "_".

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.

Make the text stream info factory method in media_handler_test_base
require the caller to specify the time scale.

The SetUpAndInitialize function returns a status. We were not
asserting that it return an OK status. This change adds the
missing ASSERT_OK calls.

Problem : Text samples have variable length and therefore act
more like continuous samples whereas audio and video
act more like discrete samples. Since we use sample
start time, a cue event could be inserted after the
start time of the last text sample and never get
inserted as there are no more samples.
Change : After all streams have requested flushing, we make sure
to collect all remaining cue events from the sync point
queue and insert them into each stream.

Problem: Sending samples to the cue alignmenet handler did
not reflect what was more likely to happen. In our
tests we would send all the samples for one stream
then all the samples for another stream. This created
some special cases that would either not happen in
reality or miss cases that would likely happen in
reality.
Changes: Changes all tests to dispatch samples in an interlaced
pattern that better reflects muxed content.

Problem: The time scale for text was being set to zero in our tests
because it was never needed.
Change: This changes it to use MS as that is what's most common and
requires the least amount of changes.

SyncPointQueue manages all cue points and returns aligned cue
points to the callers (CueAlignmentHandlers).
CueAlignmentHandler is responsible for aligning cues from different
streams. It uses SyncPointQueue internally to align / synchronize the
cue points.
