libvda is only available on ChromeOS, and being unable to link to it
with regular builds reduces our build coverage.
Add a "libvda-stub" feature that, if enabled, results in dummy C stubs
being build for all the exported libvda functions. This allows builds
with the "libvda" feature to pass, although of course the resulting
video device would immediately crash and thus should not be used.

TEST=`cargo build --features="video-decoder,video-encoder,libvda-stub"`
completes.
TEST=`cargo build --features="video-decoder,video-encoder,libvda"`
reports link errors against libvda.
TEST=`cargo build --features all-x86_64` builds libvda and completes
without error.

As we are going to introduce more media-related crates, reserve the
"media" folder as a placeholder for them, starting with the existing
libvda.
