Timothy Drews 5b659acf9a Recover from unavailable live streams.
* After updating a manifest restart any streams that failed
  to initially start.
* Seek to the stream start time only after the streams have been
  initialized, seeking before can cause lock-ups with MSE.
* Rename 'bestStartTime' to 'currentSegmentStartTime'.

Issue #21

Timothy Drews a8e567c9db Start live streams near the "live-edge".
* Construct the initial SegmentIndex for a live stream such that it
  includes at least @timeShiftBufferDepth seconds of content before
  the "live-edge".
* Use segment numbers relative to @startNumber instead of relative
  to the start of the Period in SegmentReference to handle MPDs
  with partial segment information.
* Start live streams near the "live-edge", a.k.a., "best start time",
  and start static streams at the latest start time.

Timothy Drews 069d8c3e6d Write tests and fix bugs with manifest updates.
* Write an initial set of unit tests for
  StreamVideoSource.update().
* Correctly handle new manifests that omit periods, stream sets,
  and streams that existed in the original manifest.
* Make StreamVideoSource.update() synchronous.
* Disallow merging SIDX based SegmentIndexes.

Timothy Drews bc8c2bcf49 Refactor MpdProcessor.
* Expand SegmentTemplates directly to StreamInfos instead of using
  intermediate SegmentBases and SegmentLists.
* Remove "fake" attributes from SegmentBase and SegmentUrl.
* Simplify Period duration derivation.
* Add additional unit tests.

Timothy Drews 44af1e4518 Implement initial support for live streams.
* Implement an update() method on StreamVideoSource that merges
  a new manifest into its existing one.
* Re-fetch and re-process MPDs from DashVideoSource to generate new
  SegmentReferences.
* Compute last available segment numbers and times in MpdProcessor
  when generating SegmentLists.
* Re-work Period computation in MpdProcessor.
* Handle stream EOF differently for live content.

Additional work is required to handle all "styles" of manifests.

Timothy Drews 27ed78203a Merge Segment{Base, List, Template} across levels.
* Instead of overriding SegmentBase, SegmentList, etc. between
  levels (e.g., from Period to AdaptationSet) merge them, but
  prefer elements and attributes from inner levels.
* Refactor MPD parsing unit tests into separate files.
* Rewrite SegmentBase unit tests, add SegmentList, and
  SegmentTemplate unit tests.

Timothy Drews 85cbc0e223 Fix # of segments computation in MpdProcessor.
* Correctly compute the number of segments when generating
  a SegmentList from a SegmentTemplate with a segment duration.
* Update unit tests.

Timothy Drews 3226db0d9d Handle gaps/overlaps in SegmentTimeline.
* Stretch/compress segments within a SegmentTimeline to align them
  to the beginning of the next segment.

This does not allow playback of content with actual gaps in it, but
allows MPDs with inaccurate SegmentTimelines to be used.

Closes #24, b/19144876

Timothy Drews b244def2f4 Fix-up startNumber behavior.
* Revert 5c7fca90b6, which intended
  to allow startNumber to be 0, and maintain the previous behavior,
  which requires startNumber to begin at 1 (this appears to be in-line
  with the MPD spec).
* Correctly compute the $Time$ placeholder.
* Rename firstSegmentNumber to startNumber to clarify code.

Closes #10
