KongQun Yang 74df8d30cc Exclude short segments from peak bandwidth computation
https://tools.ietf.org/html/rfc8216#section-4.1
The peak segment bit rate of a Media Playlist is the largest bit rate
of any contiguous set of segments whose total duration is between 0.5
and 1.5 times the target duration.

Fixes #498.

KongQun Yang a7463f60c1 Enable segment auto removal for live packaging
The number of preserved segments outside live window can be
configured using flag --preserved_segments_outside_live_window,
which is default to 50, i.e. 5 minutes for 6s segment.

Note that the segment removal will be disabled if it is set to 0.

Only HLS live playlist and DASH dynamic MPD are affected by this flag.

- Also add end to end tests.

Fixes #223.

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.

Fixes #315
