Dennis Kempin fa32ced1e0 Crosvm Externalization: Move libvda rust code into crosvm 
Long-term libvda will be replaced with an implementation that can
function outside of ChromeOS.

In the meantime thes allows crosvm to be built externally and pass
clippy with all features enabled.

BUG=b:191507399
TEST=Tests in crosvm and cros_sdk both pass:
  $ ./test_all
  $ cros_run_unit_tests --package=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
