mesa: add swrast_texture_image::Buffer
In the past, swrast_texture_image::Data has been overloaded. It could either point to malloc'd memory storing texture data, or it could point to a current mapping of GPU memory. Now, Buffer always points to malloc'd memory (if we're not using GPU memory) and Data always points to mapped memory. The next step would be to rename Data -> Map. This change also involves adding swrast functions for mapping textures and renderbuffers prior to rendering to setup the Data pointer. Plus, corresponding functions to unmap texures and renderbuffers. This is very much like similar code in the dri drivers.
