gallium: more elaborate tracking of front color buffer state
This fixes the case where the app calls SwapBuffers then calls glReadPixels
to read the front color buffer. We now keep track of when the front buffer
is a _logically_ copy of the back buffer (after SwapBuffers) and read from
the back color buffer instead of the front.
