Packager uses ThreadedIO to write media segments and manifest /
playlists. There was a possibility that media segments write being
delayed and scheduled after updating manifest / playlists.
This CL fixes the race condition.
Also added a note on how segments can be synced to cloud storage to
avoid the race condition during file sync.
Also added a live WebM test.
Fixes#386.

- Changed OnMediaEnd() to take (sub)segment ranges.
- Define a structure to pass the ranges.
- This requires muxers to "cache" the segment ranges but in most cases,
they already do it, e.g. 'sidx' for mp4.

Also moved MediaHandler output validation to Initialize instead.
This CL also addresses #122 with consistent chunking.

- Also sets up the packaging and verify it works.
Some of the changes are temporary to get the integration going.

The original code accumulates sample durations in seconds (double)
and then generates new segment / cluster by comparing the accumulated
value with configured value.
There may be loss of precision when accumulating values in double.
For example, with a GOP of 96 frames and frame rate of 24 fps; the
accumulated frame duration for 96 frames is 3.999999999999, which is
very close to 4.0 but not 4.0. Problem would arise if segment
duration is set to 4. The created segments would have a duration of
8 seconds instead of 4 seconds.
The new code accumulates sample durations in uint64_t relative to
input time scale; the configured segment duration will be converted to
timescale for comparison. This avoids loss of precision.

Now Finalize() will close all the files used by the segmenters. This
is important to allow WebMMuxer::FireOnMediaEndEvent to get the
correct size of the media file.
This also changes the WebM muxer to use 64-bit numbers for the init
and index ranges to correctly support >4GB files.

- Add hls_name and hls_group_id fields to MuxerOptions. This is used to
pass the NAME and GROUP-ID values for EXT-X-MEDIA tag to
MuxerListener.
- Change MuxerListener::OnEncryptionInfoReady() to take an
initialization vector.
- Change MuxerListener::OnNewSegment() to take segment name.
- Reworded and formatted MuxerListener comments to Doxygen style.
Issue #85
Change-Id: Iea06e68552a56ae180177ffd6ca315a7cf39456c
* Changed Segmenters to accept StreamInfo rather than MediaStream
to help in testing.
* Changed MemoryFile behavior to mirror local file:
* Read non-existent file is an error.
* Write deletes any existing file.
* Fixed a bug in SingleSegmentSegmenter.
Change-Id: I339e35597ca4661b7a26c6fdbbfa2f9f511c7da0
* Added WebM muxer that supports both single and multi-segment modes.
* WebM muxer supports MPD generation.
* Enabled WebM muxer and demuxer in packager.
