AFAICT the goal behind the libdrm_intel fold was to allow rapid and
seamless rework of the interface.
With a potential goal to make it a shared one, as it gets stabilised.

Currently ANV uses more than just the UAPI headers. But if we ignore
that, coping them is a bad idea.

Why - adds a, yet another, copy and making synchronisation more
annoying. First example - you blindly copied the files rather than
using `make headers_install' first ;-)
Not to mention that it makes the chicken and egg problem* even more
confusing and error prone.
