Joey Parrish cfbe5c08c2 cleanup: Convert all time parameters to signed 
This converts all time parameters to signed, finishing a cleanup that
was started in 2018 in b4256bf0.  This changes the type of:
  - timestamps
    - PTS specifically
  - timestamp offsets
  - timescales
  - durations

This excludes:
  - MP4 box definitions
  - DTS specifically

This is meant to address signed/unsigned conversion issues on arm64
that caused some test cases to fail.

KongQun Yang f49b89280c Support STYLE and REGION in WebVTT 
Note that STYLE and REGION are not supported in mp4 container due to
spec limitation as 14496-30:2014 does not specify a way to signal
styles/regions inside mp4.

Closes #344.

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.

Aaron Vaage b01de0bfb6 Disallow Copy and Assign WebVtt File Buffer 
We should never need to copy or assign the webvtt file buffer
so this change enforces that.

Aaron Vaage b3c148607f Simplify WebVtt Output 
Before, the webvtt output handler was written so that it could
share code between a segmented and non-segmented handler. As
we are not worried about that right now, this change simplifies
the handler to just be about segmented output.
