KongQun Yang 764c7077a2 Fix documentation syntaxes for RST option-list
http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#option-lists

RST only accepts two forms for option argument:
- Begins with a letter and consists of [a-zA-Z0-9_].
- Begins with "<" and ends with ">"; any characters except angle
  brackets are allowed internally.

Updated documents to obey the above rule.

Also cleaned up the documents to follow the syntaxes defined in
http://docopt.org/.

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 224b597b48 Support approximate SegmentTimeline
It is not always possible to align segment duration to target duration
exactly. For example, for AAC with sampling rate of 44100, there are
always 1024 audio frames per sample, so the sample duration is
1024/44100. For a target duration of 2 seconds, the closest segment
duration would be 1.984 or 2.00533.

This feature allows MPD generator to treat these segments as having
the same duration, thus allows MPD generator to generate less
SegmentTimeline entries and potentially no SegmentTimeline entries
(replaced with SegmentTemplate@duration instead if
  --segment_template_constant_duration flag is enabled).

Under flag --allow_approximate_segment_timeline. Disabled by default.

Fixes #330.

KongQun Yang 222737d5b5 Support UTCTiming
UTCTiming schemeIdUri and value pairs can be provided to packager using
--utc_timings flag. It should be comma separated list of
schemeIdUri=value pairs.

Note that urn:mpeg:dash:utc:direct:2014 scheme is not supported as it
requires the MPD to be dynamically generated on the fly when MPD is
served to client.

Fixes #311.
