gallium: Add texture usage flags, special-case allocation of display targets
For many envirionments it's necessary to allocate display targets
in a window-system friendly manner. Add facilities so that a driver
can tell if a texture is likely to be used to generate a display surface
and if use special allocation paths if necessary.
Hook up softpipe to call into the winsys->surface_alloc_storage()
routine in this case, though we probably want to change that interface
slightly also.
