Compile tested only. This was a deeper change than I was hoping for, due to the layering of the pipe_texture implementation in each driver on top of a shared pipe_buffer implementation in the shared code. Have modified the shared code to act as a set of convenience routines operating on nouveau_bo objects. Each driver now uses the u_resource_vtbl technique to split the implementation of pipe_resources between the existing miptree code for textures and a new, minimal buffer implementation in each driver. Eventually these should be combined, not least because APIs are now allowing things like binding buffer resources as textures and render targets.
