Bump libavutil major version to account for the LLS API/ABI changes. Commit 41578f70cf8aec8e7565fba1ca7e07f3dc46c3d2 changed the LLS API, which was called from libavcodec. Thus using an old libavcodec with a new libavutil will break. All scheduled API changes are deferred to the next bump.

avutil: Add functions for allocating opaque contexts for algorithms The current API where the plain size is exposed is not of much use - in most cases it is allocated dynamically anyway. If allocated e.g. on the stack via an uint8_t array, there's no guarantee that the struct's members are aligned properly (unless the array is overallocated and the opaque pointer within it manually aligned to some unspecified alignment).

Deprecate obsolete XvMC hardware decoding support XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it.
