Also avoid fetching manifest updates when minimumUpdatePeriod is
missing. In the absence of minimumUpdatePeriod, just reprocess
the MPD we already downloaded.
Closes#69, #70.

Strip extraneous minBufferTime copies.
Default minBufferTime in MpdProcessor if missing.
Pass minBufferTime as a parameter to Stream.start().
Keep a buffering goal separate from minBufferTime, which will only
be used for stream startup (as intended by the DASH spec).
This allows us to startup quickly and still buffer ahead.
Relates to #51.

* 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.

Change-Id: I3c553a1b7120a59c68f19cdc85f412f31972c1b8
* 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.
Change-Id: I203e269bd9dfb1fb1cc4ca48be29043c1ee4007b
* 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.

Assume a year is 365 days and a month is 30 days. Supporting years and
months is useful as some MPDs that describe live content specify
@minimumUpdatePeriod in terms of years; here, an accurate number of
seconds is not needed, but the duration string should not be treated as
invalid.

* 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.
Change-Id: I3fdb7657bb9f468e10f63e47e9a52fbf8ebbd40b
* 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
Change-Id: I9b565edc9e23b9ad7c6bc62829d6b0ab565008a4
* Adjust SourceBuffer timestamps forward by the Period's
start time and backwards by the Representation's
presentationTimeOffset.
* Incorporate the start time of a Representation's first
segment in the calculation of a Period's duration.
* Seek to the latest start time before starting playback.
Further adjustments will be required to support live playback.

AdaptationSets are sorted by language (audio-only), then by those with
the "main" role. Main sets are preferred when there are multiple to
choose from.

Most of these StringUtils were either operating on Uint8Arrays directly
or using strings to move around Uint8Array data anyhow.
Change-Id: I71efe6ede34210ca721d46acd53452344efff5bb
* Create generic stream description classes to represent
Representations, AdaptationSets, and Periods.
* Move generic stream selection logic out of MpdProcessor and
into StreamInfoProcessor.
* Refactor DashVideoSource and DashStream to use the generic
stream description classes.
A follow-up patch is required to re-organize files and namespaces.
