JCTVC-J0533 Chroma CBF cleanup [P. Kapsenberg (Intel)] [late]

This contribution claims that the context increment for cbf_cb and cbf_cr can exceed the maximum value intended. A solution is proposed that clamps the context increment to 2.

Relates to bug with ticket #576

Impact on 4:4:4? Would in principle be possible, but would restrict the number of contexts.

Would it support larger CTB sizes than 64 which might require tree depth > 3?

Another solution is suggested that adds and specifies the additional context (but that would currently not be used) – Benjamin Bross will take action.
