Implemented MPEG-2 Stream Encryption Format for HTTP Live Streaming
specified in https://goo.gl/N7Tvqi.
This change also moved ProgramMapTableWriter creation from TsWriter
to TsSegment.
Issue #165
Change-Id: Ia89dd16a5e6405706dd3d85ec6b6de580f7b13a7
Added a flag --strip_parameter_set_nalus. When enabled, parameter
set NAL units, SPS/PPS for H264 and SPS/PPS/VPS for H265, are stripped
from frames when converting NAL byte stream (AnnexB stream) to NAL
unit stream, which generates avc1/hvc1; otherwise they are not
stripped, and avc3/hev1 is generated.
Parameter set NAL units should not be stripped if they are varying
in the frames otherwise the frames may fail to be decoded.
The flag is enabled by default as we don't usually see varying
SPS/PPS/VPS and it is more space efficient with them stripped.
Set --strip_parameter_set_nalus=false to disable the flag if there
are varying SPS/PPS/VPS in the frames. This addresses #206.

- Cannot include PMT for following encrypted segments in the clear lead.
Some players consider them as conflicting codecs.
- Add EXT-X-DISCONTINUITY in front of first EXT-X-KEY to notify that the
codec is switching from e.g. "avc1" to "zavc".

- For encrypted segments, PMT specified by SAMPLE-AES specification is
generated.
- Remove time_scale_ field from TsWriter. It is not used.
- Move ContinuityCounter to a separate file.
- Add ProgramMapTableWriter and implementations.
- continuity_counter is incremented for PAT and PMT.

- Segmenter should not finish a segment unless the next sample is a key
frame.
- Renamed PesPacketGenerator::Finalize() to Flush().
- Use duration from the sample instead of the one copied to PesPacket.
- Remove duration field from PesPacket.
