Kongqun Yang bee59bc2fc Enable generate_dash_if_iop_compliant_mpd by default
This will move ContentProtection element from Representation
to AdaptationSet.

Shaka Player already supports AdaptationSet switching
urn:mpeg:dash:adaptation-set-switching:2016;

ExoPlayer does not support it yet. Filed
https://github.com/google/ExoPlayer/issues/2431 to track the issue.

(ExoPlayer does not like having ContentProtection in Representation
anyway)

Kongqun Yang 80c54a533a Update cmd flags to support static mpd with live profile
- Deprecated command line flags --profile and --single_segment.
  'segment_template' in stream descriptors implies live profile
  and non-single segment.
- Added flag --generate_static_mpd_for_live_profile to generate
  static mpd for live profile; if not set, dynamic mpd will be
  generated.

Cues used to be generated in the end of the file; if http range

- Tracks other than video are protected using whole-block full-sample
  encryption as specified in ISO/IEC 23001-7:2016(E) 9.7, which is
  equivalent to a pattern of 1:0. This is different to the non pattern
  encryption counterparts.
- Also updated the code to allow the existence of other protection
  schemes in the original content, which will simply be ignored.
- The internal cryptor used by AesPatternCryptor should not use
  constant iv, add a DCHECK for that.
- Optimize AesPatternCryptor handling on the special pattern 1:0.
