API changes, most recent first:
+2018-xx-xx - xxxxxxx - lavu 56.9.100 - aes_ctr.h
+ Add method to set the 16-byte IV.

2018-01-xx - xxxxxxx - lavf 58.5.100 - avformat.h
Explicitly make avformat_network_init() and avformat_network_deinit() optional.
If these are not called, network initialization and deinitialization is
