As far as solid/copy and off-screen pixmaps, nothing changes from the
driver's perspective.

For Composite, an optional CheckComposite hook is added which lets you
send a composite op to software before any migration occurs.  This is
critical for performance when an op will result in a software fallback. 
If you get the render accel working, adding CheckComposite is quick.  Be
sure to check with rendercheck from xapps, ignoring the dst coords test
which is broken due to my xlib cluelessness.

I'm extremely close to getting r100 render accel working.  After that,
I'm planning on testing r128 one more time and just committing all this,
and sorry for the messiness of the diffs that will be produced but
disentangling would be quite a bit of work.
