* Move seek range updates into SegmentIndex implementations
and StreamVideoSource.
* Remove unnecessary sub-class hooks from StreamVideoSource.
* Remove internal LiveSegmentIndex timer: do SegmentReference eviction
and generation on demand.
* Rework Stream startup again: consider Streams as started when they
have buffered some minimum amount of content. As part of this, only
apply a timestamp correction to the SBM when the streams have started.
* Defer stream switches until all SegmentIndexes have been corrected.
* Partially revert optimistic "bufferedAhead" calculations in Stream:
check if we've buffered enough content at least every second.
* Make LiveSegmentIndex more robust against a "wrong"
@availabilityStartTime.
* Fix a bug where a positive timestamp correction would trigger an extra
Stream resync.
* Fix a bug in evict_() where the first segment would never get evicted.
* Check stream started conditions in onUpdate_ instead of after a segment
has been inserted.
* Tidy-up immediate/clearBuffer naming and other comments.

* Allow segments from different streams (Representations) to coexist
in buffer.
* Only fetch a single segment at a time.
* Remove id field from SegmentReference and remove SegmentRange.
* Only start the Streams once the buffer is "full".
* Stop DashVideoSource from triggering an extra resync during startup.
* Make Task.abort call order deterministic.
A follow-up patch is required to handle certain seek patterns in
live streams.
Issue #51
Change-Id: Ib7c9021471f1ed89323f19764463202b119cb491
* Rename SegmentIndex functions to shorter names.
* Add first() and last() functions for convenience.
* Throw exceptions for out of range errors.
* Handle more corner-cases in merge().
* Add more unit tests.

* The segmentNumber member in SegmentReference is used as an ID,
so rename it and update the doc string.
* Tidy up SegmentIndex unit tests.
Change-Id: I888b8cbfd6a198bab09f6ab846cbdbf70cfcaa5a
* 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.
Issue #21
Change-Id: I3c553a1b7120a59c68f19cdc85f412f31972c1b8
* 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.
Issue #21
Change-Id: I38be9513dc73e4683d1079b4dedb489e8206043d
* Move internal non-DASH specific code into the 'media' namespace.
* Remove DASH references from generic stream code.
The documentation is not changed as a follow-up patch will factor out
DASH functionality from StreamVideoSource back into a new
DashVideoSource class.
