KongQun Yang d9e7e2f1d0 Generate two sample entries only if there is clear lead
This addresses playready broken with clear lead = 0.

clear lead != 0 is still broken with playready on Edge. We think it is
likely an Edge bug, which does not support multiple sample entry boxes,
thus does not support clear lead.

Kongqun Yang d007ddf20b [MP4] Make outputs CMAF compatible
- Added flag --mp4_include_pssh_in_stream, default to true. If it is
  set to false, the encrypted mp4 stream will not include pssh.
- Align BytesOfProtectedData to multiple of 16 bytes for cenc.
- Set TrackHeader flag to kTrackEnabled | kTrackInMovie |
                          kTrackInPreview
- Move mvex to after trak, required by HLS
- Add cmfc/cmfs compatible brands except for avc3/hev1, where CMAF
  requires single initialization switching set which is not supported.
- Set duration to 0 in tkhd, mdhd, mvhd.

Also updated major_brand and compatible brands:
- Set major_brand to isom (iso-bmff media file format) and made dash
  a compatible brand
- Replaced compatible brand iso6 with iso8 since we use sthd for text
  tracks

Fixes b/36278260

Kongqun Yang 1af8f04e40 Rename webm_subsample_encryption flag to vp9_subsample_encryption
This is what webm_subsample_encryption flag actually does.

- Fixes the flag not working problem introduced by previous CLs.
- Also mark flag webm_subsample_encryption as deprecated.

Closes #220

KongQun Yang b09c8f6521 Update EncryptionHandler to support key rotation and SampleAes
This CL also removes EncryptionConfig stream data type and merges it
into StreamInfo/SegmentInfo instead.

Kongqun Yang 160700b452 Integrate ChunkingHandler
Also moved MediaHandler output validation to Initialize instead.

This CL also addresses #122 with consistent chunking.

Kongqun Yang 9990524f98 Implement ChunkingHandler
This handler is a multi-in multi-out handler. If more than one input is
provided, there should be one and only one video stream; also, all inputs
should come from the same thread and are synchronized.
There can be multiple chunking handler running in different threads or even
different processes, we use the "consistent chunking algorithm" to make sure
the chunks in different streams are aligned without explicit communcating
with each other - which is not efficient and often difficult.

Consistent Chunking Algorithm:
 1. Find the consistent chunkable boundary
 Let the timestamps for video frames be (t1, t2, t3, ...). Then a
 consistent chunkable boundary is simply the first chunkable boundary after
 (tk / N) != (tk-1 / N), where '/' denotes integer division, and N is the
 intended chunk duration.
 2. Chunk only at the consistent chunkable boundary

This algorithm will make sure the chunks from different video streams are
aligned if they have aligned GoPs. However, this algorithm will only work
for video streams. To be able to chunk non video streams at similar
positions as video streams, ChunkingHandler is designed to accept one video
input and multiple non video inputs, the non video inputs are chunked when
the video input is chunked. If the inputs are synchronized - which is true
if the inputs come from the same demuxer, the video and non video chunks
are aligned.
