Sorry for the breakage.

Attached are patches that replace calls to xf86UDelay with usleep. I
couldn't find anywhere in -glint or -neomagic that xf86UDelay was
called--so if there is a place, point it out to me. Also attached is a
patch to chmod +x autogen.sh in -ast. The patches are compile tested
only.

While I did not mean to break these drivers, the fact that they went
for a couple months without any feedback tells me that they're
entirely unused.

If the ABI was already broken, I don't see any reason to 'fix' it by
adding this function back in.
