I want to be able to copy between buffer objects using BLORP in the i965
driver. Anvil already had code to do this, in a reasonably efficient
manner - first using large bpp copies, then smaller bpp copies.
This patch moves that logic into BLORP as blorp_buffer_copy(), so we
can use it in both drivers.
