Tatsuyuki Ishi 7a4c220485 media: ffmpeg: Free AvPacket through av_free_packet. 
We used to unref the owned AVBufferRef manually but this is actually
handled by ffmpeg if you call the right destructor for AVPacket.

Do that, remove our internal ownership handling for AvPacket and add a
unit test to confirm we don't leak memory.

BUG=None
TEST=cargo test -p ffmpeg &&
     cargo test --features "video-decoder,ffmpeg" -p devices video

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
