feat: get start number from muxer and specify initial sequence number (#879)
Set the start number in representation to the segment index that is sent by muxer.

With this enhancement, you can now specify the initial sequence number
to be used on the generated segments when calling the packager.
With the old implementation, it was always starting with "1".

feat: default text zero bias (#1330)
A positive value, in milliseconds. It is the threshold used to determine
if we should assume that the text stream actually starts at time zero.
If the first sample comes before default_text_zero_bias_ms, then the
start will be padded as the stream is assumed to start at zero. If the
first sample comes after default_text_zero_bias_ms then the start of the
stream will not be padded as we cannot assume the start time of the
stream.

feat!: Rewrite build system and third-party dependencies (#1310)
This work was done over ~80 individual commits in the `cmake` branch,
which are now being merged back into `main`. As a roll-up commit, it is
too big to be reviewable, but each change was reviewed individually in
context of the `cmake` branch. After this, the `cmake` branch will be
renamed `cmake-porting-history` and preserved.

KongQun Yang 51d39d96a1 Add offset to tranport streams (MPEG2-TS, HLS Packed Audio)
Configurable with --transport_stream_offset_ms.

This is needed to compensate for possible negative timestamps in
inputs, which could happen on ISO-BMFF with EditLists.

Issue #112.

KongQun Yang 1742e03471 Drepcate --num_subsegments_per_sidx
This flag was designed for two purpose:
- Grouping fragments into subsegments, achieving three level hierarchy:
  segment < subsegment < fragment.
- Indicate whether to generate 'sidx' box in media segments (when the
  value is set to a negative number).

There are no practical use case for the first purpose. Removing it to
simplify the code and reduce the confusion.

Introduce another flag --generate_sidx_in_media_segments for the second
purpose.

KongQun Yang f089d1d0d4 Deprecate --mp4_use_decoding_timestamp_in_timeline
It was implemented to workaround Chromium's DTS
https://crbug.com/398130, but the workaround does not really work in
all situations.

Remove it now as we already have another workaround available.

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 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.
