Revert "r300g: rebuild winsys/pipe buffer handling and add buffer map"

This reverts commit fff5be8e7b4557c221f2425dcafc2e7cbbba76ba.

Probably went too soon with this, dileX reported OA not working for him
it works here fine, but the optimisations I wanted aren't working properly
yet so I'll fix that now.
