KongQun Yang f8a1cb66ad 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 718fce068d Refactor DashIopMpdNotifier Part 2
Move AdaptationSet related functions to the new Period class, which
maps to <Period> element and provides methods to add AdaptationSets.

Kongqun Yang af0904e428 Fix AdaptationSet switching signaling
Current mechanism of using AdaptationSet @group is not spec compliant.

The spec compliant mechanism is to use supplemental descriptor with
schemeIdUri: urn:mpeg:dash:adaptation-set-switching:2016 as specified
in ISO/IEC 23009-1:2014/Amd.4:2016.

Fixes #156

Rintaro Kuroiwa 981041a3a8 Remove locks from MpdBuilder and lock at MpdNotifier level
- Since most use cases use notifier implementations that already uses
  locks, removing locks from MpdBuilder.
- Added locks to MpdNotifier::Flush() implementations. Multiple threads
  were able to write to the same file.

Rintaro Kuroiwa 76e5be3756 More fix for live
- Neither live with or without key rotation did not output the right
  result.
- No key rotation: did not produce any ContentProtection element.
- With key rotation: did not have DRM specific ContentProtection.
- To get key rotation working with shaka player, <cenc:pssh> elements
  are removed.
