gallium: unify transfer functions
"get_transfer + transfer_map" becomes "transfer_map". "transfer_unmap + transfer_destroy" becomes "transfer_unmap". transfer_map must create and return the transfer object and transfer_unmap must destroy it. transfer_map is successful if the returned buffer pointer is not NULL. If transfer_map fails, the pointer to the transfer object remains unchanged (i.e. doesn't have to be NULL). Acked-by: Brian Paul <[email protected]>
