File avcodec.h

AVDictionary is provided for compatibility with libav. It is both in implementation as well as API inefficient. It does not scale and is extremely slow with large dictionaries. It is recommended that new code uses our tree container from tree.c/h where applicable, which uses AVL trees to achieve O(log n) performance.
