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.

Aaron Vaage 16eff80497 Made StreamData Have Const Pointers
In prep for changes to Trick Play, we want to make all messages
copy on write so that if the same message is sent to multiple
handlers, it is not possible for one handler to change the data
another handler is using.

Jacob Trimble abb1abf5c5 Rename StreamInfo::extra_data to codec_config.
Since the |extra_data| field contains codec-specific configuration
data, it makes sense to call it |codec_config|.

KongQun Yang 8c202047fb Make edash-packager outputs predictable for testing
- Added --iv to inject iv for fixed key encryption.
- Added support for key rotation in fixed key encryption.
- Added --use_fake_clock_for_muxer to set timestamp to 0 in the output.

Also updates stream info dump message:
- Modified pixel_width: %d\n pixel_height: %d to pixel aspect ratio: %d:%d
- Removed language from video stream info.

These flags should only be used for testing.

KongQun Yang 15ae26e12f Modify include headers to have "packager" in the path
This is a follow up to previous CL.

Generated using command:
find {media,app,mpd} -type f -exec sed -r -i 's/#include "(.*)"/#include
"packager\/\1"/' {} \;

common.gypi and mpd.gyp are also modified to take the path change into
consideration.
