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 also allows setting the language of different text streams from
the same input. Multiple streams can use the same input stream
using different cc_index values and can each use a different language.
This also will try to pull the language from the input if not
specified.

This also changes the callbacks a bit to (a) avoid passing references
for already ref-counted types, and (b) don't pass PID since the
parent knows this and gives it to the child parser.

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.
