This is new in libdrm 2.4.89, but we're still only requiring >= 2.3.1
(lulz). I've bumped the requirement in configure.ac and meson.build.

In 2/7, you begin using a #define from randrproto 1.6 without requiring
it; I've fixed that too.

With those changes, merged 1-5 of this series:

I didn't merge 6/7 because libxcb has the following dumbness:

desoxy:~% pkg-config --modversion xcb-randr
1.12

That is, of course, the libxcb version number, not a reflection of the
randr protocol it supports. I don't have a good solution for that yet.
At any rate it would break the build for people without git-fresh xcb
bits, so it's left out for now.

Likewise I didn't merge 7/7 because you'd said you would change it to a
command line option.
