Quotient reduction to minimal form does not work well in practice due to
rounding of the inputs.

- subSegmentAlignment logic assumed that all Representations were
added before calling Representations::AddNewSegment() on any
Representation in an AdaptationSet. It is not a valid assumption
for VOD and is removed.

- 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.

- 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.

- The UUID and DRM name can be fetched from KeySource.
- Add ProtectedContent message to MediaInfo. The message contains basic
information for the protected content, such as the default key ID for
the content.
- The message is required to separate Representations with different
content protection information into different AdaptationSets.

- 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.

- The fields used to be repeated but there is no use case at the moment.
- DASH IOP explicitly disallows segments with multiple tracks.
Change-Id: Ia0af2048210c546dfaa178735605a81052ea1123
- 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).

- Get the first sample duration in Segmenter.
- Pass the value all the way to Representation thru MuxerListener.

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.

MSE requires 'base-data-offset-present' not to be set, but FFmpeg may
generate fmp4 files with this flag though it actually uses moof as base.
Log a warning instead of failing directly in this case.
FFmpeg may also generates fmp4 files without tfdt box
(TrackFragmentDecodeTime) box, which is again non-MSE compliant. Handle
this scenario properly.

Also fixes a test failure in SegmentTemplateTest introduced in an earlier
change.

Also rename mpd/base/bandwidth_estimator_test.cc to
bandwidth_estimator_unittest.cc for consistency.
And remove mpd/base/simple_vod_mpd_notifier.* as they are not used
anywhere.

This is a follow up to previous CL.
Generated using command:
find {media,app,mpd} -type f -exec sed -r -i 's/#include "(.*)"/#include
"packager\/\1"/' {} \;
common.gypi and mpd.gyp are also modified to take the path change into
consideration.
