Vegard Kamsvåg b3aad24952 aya: adds support for AF_XDP
Contains user-space functionality for doing
AF_XDP socket interactions. Much is copy-paste
from xdpilone, but with higher-level abstractions
put on top.

It should be usable at a high level without requiring
unsafe code on the library user's side. The more
low-level control is still available, for power users
who need that level of control (and accept the safety
implications).
