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 ce932f68a2 Change AV1 cbcs to protect all bytes of decode_tile structure
AV1-ISOBMFF spec is updated recently to use start alignment instead of
end alignment for cbcs:

for the protected scheme cbcs:
- BytesOfProtectedData SHALL start on the first byte and end on the
  last byte of the decode_tile structure (including any trailing bits).
- A subsample SHALL be created for each tile, even if its size is less
  than 16 bytes.
- ...

cenc protection scheme is not affected.

Closes #698.
