Part of https://github.com/shaka-project/shaka-packager/issues/369
This adds read support for some MPEG-TS PMT elementary stream
descriptors:
- ISO639 Language Descriptor providing language code and audio type
- Maximum Bitrate Descriptor providing peak stream bandwidth
Those metadata are propagated to StreamInfo structures:
- StreamInfo.language field
- AudioStreamMetadata.max_bitrate field for audio streams
- audio type is currently not propagated - corresponding field has to be
added to AudioStreamMetadata
Test vector file containing those descriptors is provided.
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.

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.

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.

Since the |extra_data| field contains codec-specific configuration
data, it makes sense to call it |codec_config|.

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.
