feat: port media/event to CMake (#1222)
Rebasing #1155 and applying some fixes. Had to comment out the
`mpd_notify_muxer_listener_unittest` because it depends on
`MockMpdNotifier` from `mpd/base` which has not been ported yet. Can
bring this test back once that has been ported.

fix: Low Latency DASH: include the "availabilityTimeComplete=false" attribute (#1198)
# Low Latency DASH - `availabilityTimeComplete=false`

Low Latency DASH manifests generated by Packager were missing the
attribute `availabilityTimeComplete`. As per the [DASH
specs](https://dashif.org/docs/CR-Low-Latency-Live-r8.pdf):

**_the AdaptationSet@availabilityTimeCompleteshould be present and be
set to 'FALSE'_**

## The Issue
The missing attribute caused ULL streams from Shaka Packager to no
longer be compatible with DASH.js. Previous versions of DASH.js allowed
users to specify ULL mode when initializing the player. However, the
most recent releases of DASH.js automatically detect ULL by scanning the
manifest for ULL specific attributes. Although there are many attributes
only associated with ULL, [DASH.js only greps for
`availabilityTimeComplete` in its detection
logic](https://github.com/Dash-Industry-Forum/dash.js/blob/development/src/streaming/controllers/PlaybackController.js#L792-L805).
Because of the missing attribute in Packager and the limited ULL
verification criteria by DASH.js, Packager streams were not being
treated as low latency streams by DASH.js.

## Testing
### Unit Testing
`./mpd_unittest
--gtest_filter="SegmentTemplateTest.OneSegmentLowLatency"`
` ./mpd_unittest
--gtest_filter="LowLatencySegmentTest.LowLatencySegmentTemplate"`

### Manual Testing
- Created a low latency stream with Shaka Packager
- Observed the expected `availabilityTimeComplete=false` attribute in
the generated DASH manifest.

Fix for gap size warning in Low Latency mode (#985)
## The issue
- With LL-DASH mode enabled, the gap size warning was hit and printed to the console every time a new segment was registered to the manifest.
- This occurred because the first chunk's size and duration were being stored for each segment, rather than the full segment size and duration. Note, only the first chunk's metrics are known at first because in low latency mode, the segment is registered to the manifest before it is finished being processed and written.
- Because of this, the gap size check was comparing the end time of the first chunk in the previous segment to the beginning time of the current segment, causing the check to fail every time.

## The Fix
- Update a low latency segment's duration and size once the segment file has been fully written.
- The full segment size and duration will be used to update the bandwidth estimator and the segment info list. 
- Updating the segment info list to hold the full duration is necessary for satisfying [the gap size check found in Represenation.cc](https://github.com/google/shaka-packager/blob/master/packager/mpd/base/representation.cc#L391).
- NOTE: bandwidth estimation is currently only used in HLS

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 4766654b4d Add TTML text output.
This only supports TTML output; meaning the user can convert WebVTT
into TTML, but not the other way around.  This will be useful for
DVB-sub subtitles that would be better supported within TTML.

This only adds text-based output; a follow-up will add MP4 support.

Jacob Trimble 56908a83a7 Convert text WebVTT output to muxer.
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.

[DASH] Support signalling of last segment number (#713)
Per https://dashif.org/docs/DASH-IF-IOP-v4.3.pdf 4.4.3.6 Signalling the last segment number in Period, there are three ways to signal the last segment number:

  a. Use the lmsg signalling as defined in clause 4.4.3.5.
  b. Use the Segment Timeline with @r value greater or equal to 0.
  c. Add a Supplemental Descriptor with @schemeIdUri set to http://dashif.org/guidelines/last-segment-number with the @value set to the last segment number.

We do not support (a). This change adds support for (c) when Segment Timeline (b) is not used, i.e. when Representation has constant duration (could be approximate).

Under flag --dash_add_last_segment_number_when_needed (disabled by default).

KongQun Yang b85e5c9368 Use segment duration in buffer depth calculation
Segment start,end time was used previously, which could result in
problems if there are discontinuity in the streams. E.g. if the
stream has timestamp, 10000, 10001, 10002 and then next segment
comes in with timestamp 1. With the previous logic, all the segments
would remain in the time shift buffer until after 10000 segments
even with a small time shift buffer depth of 10.

This could also happen when timestamp wraps around, which could
happen during long time of live streaming.

This change will also be useful to support multi-period live DASH.
