- Use std::move to transfer ownership.
- Avoid libxml primitives outside XmlNode.
- Have attribute setting return errors.
- Mark bool returns with WARN_UNUSED_RESULTS and use return value.
- Use std::string over char*.

KongQun Yang adc9549e2d Add new URL fields in MediaInfo
The file_name fields will be used to solely indicate file paths on the
designated file system, and they are used to do normal file operations,
including file creation, file updating and file removal if needed;
added new xxx_url fields, for the URLs that should appear on DASH
manifest or HLS playlists.

xxx_url are the URIs of the media in the manifest. The fields are
converted from file_name fields but adjusted to be relative to DASH
manifest path or HLS playlist path, optionally with base_url prepended.

Previously the file_name fields are converted in place to indicate
URLs when passing to manifest / playlist builders. The original file
names were lost, which made it difficult to remove files outside of
live window.

Now that the input file names are preserved. File system APIs can
operate on the original file names while manifest / playlist generation
functions can operate on URLs.

Issue: #233

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.

Joey Parrish f3e19fc002 Split AdaptationSets by content type, container, codec, and language
This adds a new function to key AdaptationSets based on the
characteristics that require separate sets.

With this, we are now able to package multi-codec assets at once
(AVC1/MP4 and VP9/WebM in the same manifest, but in different
AdaptationSets).

  'dynamic' MPD.
- Period@id is always set to "0".
- MPD@publishTime is set to the time when the MPD is output.

Rintaro Kuroiwa fe851f692b Calculate (sub)SegmentAlignment for AdaptationSets
- AdaptationSet::OnNewSegmentForRepresentation() calculates whether the
  Representations are aligned by looking at the start time and duration.
  (Except that duration is not used in this implementation).
- Add RepresentationStateChangeListener to callback
  AdaptationSet::OnNewSegmentForRepresentation() from Representation.

Rintaro Kuroiwa 60c54975d7 MpdBuilder should not automatically add ContentProtection elements
- ContentProtection elements should be added explicitly by the
  AddContentProtection() methods.
- This is because some MPDs should have ContentProtection at
  AdaptationSet level instead of Representation.
- Change SimpleMpdNotifier, which uses MpdBuilder, to add
  ContentProtectionElements. The logic is moved from MuxerListener.
- Add Element class for specifying subelements for
  ContentProtectionElement.

Rintaro Kuroiwa 21e43966db Use pixel_{height,width} to set AdaptationSet@par
- Pass pixel_height and pixel_width from VideoStreamInfo to MediaInfo.
- par can only be set if all the Representations have the same
  picture aspect ratio. That is the ratio of sar_x*width:sar_y*height
  should all be the same.
- If there is a Representation that does not have the sar attribute set,
  par is also not set.

Rintaro Kuroiwa a02e3b60df max{Width,Height,FrameRate} for AdaptationSet
- DASH IOP requires AdaptationSets with video Representations to have:
  @maxWidth (or @width if all the Representations have the same width).
  @maxHeight (or @height if all the Representations have the same width).
  @maxFrameRate (or @frameRate if all the Representations have the same
  frame rate).

Joey Parrish 77ec23afe4 Split up AdaptationSets by language.
Additionally, for XML schema correctness, convert ISO-639-2 language
tags (three-letter codes) to ISO-639-1 tags (two-letter codes) when
possible.  This follows BCP-47, which says to always use the shortest
language tag when there are multiple possibilities.
