KongQun Yang 8257eea804 Bug fixes and clean-ups for I-Frame playlists
- Add empty lines between different types of renditions to improve
  readability.
- Group variants with the same audio/text group together, as it is
  where the Adaptation occurs.
- Write master playlist after writing media playlists. This makes
  more sense and it is also necessary to have the bandwidth of
  the last iframe playist segment correctly computed.
- For fMP4, I-Frame segment must include the 'moof' header.
- Fix a problem that hls_iframe_playlist_name is not passed to
  MuxerListenerFactory.

Aaron Vaage e98a150d62 Added DEFAULT and AUTOSELECT for Text
Took the same logic for DEFAULT and AUTOSELECT used by audio and
applied it to text. Combined the build tag logic for audio and
text as they were the same expect for a couple fields.

Aaron Vaage 44847a0737 Changed Group Name Fallback
If no hls group name is given, we would default to "audio" but as
we are working to support text, this won't make sense to see
GROUP="audio" on a text stream.

Instead default to "default-audio-group" for audio streams. A specific
text default will be added later.

Aaron Vaage 0f17631017 Use Variants To Build Audio and Video Tags
In the master play list, use a class called variant to build
the video tags.

The variant list will always have one entry. In the case that there
are no audio streams, the variant list will have a null entry.

KongQun Yang 32d26094ba [HLS] Support AUTOSELECT and DEFAULT in EXT-X-MEDIA
According to HLS spec: https://goo.gl/MiqjNd 4.3.4.1.1. Rendition Groups
- A Group MUST NOT have more than one member with a DEFAULT attribute of
  YES.
- Each EXT-X-MEDIA tag with an AUTOSELECT=YES attribute SHOULD have a
  combination of LANGUAGE[RFC5646], ASSOC-LANGUAGE, FORCED, and
  CHARACTERISTICS attributes that is distinct from those of other
  AUTOSELECT=YES members of its Group.

We tag the first rendition with a particular language in an audio group
with 'AUTOSELECT'; it is tagged with 'DEFAULT' too if the language
matches --default_language.

KongQun Yang b3194866a6 [HLS] Add CHANNELS attribute to #EXT-X-MEDIA
As specified in HLS spec (https://tools.ietf.org/html/rfc8216):

All audio EXT-X-MEDIA tags SHOULD have a CHANNELS attribute.  If a
Master Playlist contains two Renditions encoded with the same
codec but a different number of channels, then the CHANNELS
attribute is REQUIRED; otherwise, it is OPTIONAL.

KongQun Yang 2db1867951 Write manifests atomically
In the original manifest updating process, the file was truncated first
before was written with new contents. There is a small chance that
the web server may read back empty file or incomplete file.

The new code makes the update operation atomic (by writing to a temporary
file first then replace the old file with the temporary file).
