[PATCH] modeset: Split buffer allocation to a separate file

thanks!  I've pushed to a branch on my github tree, in case you want
to double check that I'm not missing anything:

  git://github.com/robclark/libdrm.git  modetest branch

will do some sanity testing a bit later, and if that looks ok and no
one objects, I can push to fd.o

BR,
-R
