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.

KongQun Yang 796974d2a1 [DASH] Support custom Accessibility and Role elements
Add dash_accessibilities stream descriptor, which is a semi-colon
separated list of accessibility_scheme_id_uri=value. It is optional.

Add dash_roles stream descriptor, which is a semi-colon separated
list of strings. It is optional.

Closes #565.

KongQun Yang 335a659fab [DASH] Fix possible incorrect segmentAlignment in static live profile
DASH live profile with static MPD was incorrectly handled in the same
way as live profile with dynamic MPD, i.e. by assuming the synchronized
Representations, which is incorrect.

It can be easily re-produced in multiple period outputs, i.e. with Ad
cues. It may happen with regular contents as well, due to race
condition, though with a much lower chance of occurring.

Fixes #435.

KongQun Yang 0ef078a23b Fix default_language not effective with 2-char code
Two-character ISO-639 code in --default_language was ignored due to
a bug in language code matching as the language code in stream is
always converted to 3-character code.

Fixes #371.

KongQun Yang 6ffa344553 Moves AdaptationSet@id management out of Period class
It is now managed in SimpleMpdNotifier.

This avoids unnecessary increment in AdaptationSet id counter.

Also makes sure the AdaptationSet is sorted by id in XML output.

KongQun Yang ee9b7f6392 Calculate presentationTimeOffset and Period@duration from segments
Prefer timestamps from Video AdaptationSets if available - this avoids
possible video playback jitters due to gaps.

presentationTimeOffset is not applied to the first period as it may in
negative dts which Chrome does not like: https://crbug.com/398141.

It is safe to apply to subsequent periods as the actual offset applied
takes Period@start into consideration:

    offset = Period@start - presentationTimeOffset

The result timestamp with offset applied is close to Period@start, so
it is unlikely to result in a negative dts value.

Closes b/73899306.

KongQun Yang ef2c424876 Implement Representation::GetDurationSeconds
Also added Period::GetAdaptationSets and
AdaptationSet::GetRepresentations.

Instead of implementing GetDurationSeconds in all MpdBuilder classes
(MpdBuilder/Period/Adaptation/Representation) like what we used to do
with GetEarliestTimestamp, the two new functions allows MpdBuilder to
iterate through the Representations to get durations.

Also updates GetEarliestTimestamp functions to use the same iteration
method.
