Tokstyle no longer allows:
* Includes inside an `extern "C"`
* Comments on function definition and declaration to be different.
* Doxygen comments commenting on other doxygen comments.
This change does not include the addition of VP9. We do that in a

Changes:
* fix the video bug (video frames larger than 65KBytes) by sending full
frame length in alternate header field
* improve video frame reconstruction logic with slots
* configure video encoder and decoder to be multihtreaded
* set error resilience flags on video codec
* change encoder and decoder softdeadline
"All rights reserved" was incorrect. The project was licensed under GPL3,
which means a lot of rights are licensed to everybody in the world, i.e.
not reserved to the "Tox Project".

operators, but there seems to be no option for that.
