[PATCH 00/21] Misc dead code cleanup

[Adam Jackson]

No real unifying theme here besides cleanup.

Two patches here do require trivial driver changes.  06/22 removes an
interface that simply can't work; naturally, two drivers (trident and
xgixp) do in fact use it.  The fix requires no thought beyond
copypasta of, say, vesa's shadow setup code.  22/22 will break the
build of i810 mga savage and tdfx, but all they're doing is setting the
ValidateTree slots to NULL (which they already are at init time) so the
fixes there require even less thought.

I'm happy to fix all of the above before this is merged.
