This CL adds support for the new GAVD backend that connects directly to a Chrome media::VideoDecoder through the new mojo::VideoDecoder interface. The mojo::VideoDecodeAccelerator interface currently used by the GAVDA libvda backend is deprecated and will be removed in the future. To enable the libvda GAVD backend the "--video-decoder=libvda-vd" argument needs to be provided to crosvm.

Libvda Rust wrapper
Note: This crate is specific to ChromeOS and requires the native (libvda)[https://source.chromium.org/chromiumos/chromiumos/codesearch/+/main:src/platform2/arc/vm/libvda] library at link time.
Rust wrapper for libvda. This library is used to enable communication with Chrome's GPU process to perform hardware accelerated decoding and encoding. It is currently in development to be used by crosvm's virtio-video device.
Building for the host environment
You can also execute cargo directly for faster build and tests. This would be
useful when you are developing this crate. Since this crate depends on
libvda.so, you need to install it to host environment first.
(chroot)$ sudo emerge chromeos-base/libvda # Install libvda.so to host.
# Build
(chroot)$ cargo build
# Unit tests
(chroot)$ cargo test
