i965: Support images with aux buffers
Previously images did not support any auxiliary compression surfaces
(CCS, MCS, or HiZ). That's about to change. This patch just adds the
fields to __DRIimageRec to make auxiliary surfaces possible.
v2 (Jason Ekstrand):
- Add an aux_pitch parameter as well as aux_offset
