gallium: allow choosing which colorbuffers to clear
Required for glClearBuffer, which only clears one colorbuffer attachment.
Example:
If the first colorbuffer is float and the second one is int:
pipe->clear(pipe, PIPE_CLEAR_COLOR0, float_clear_color, ...);
pipe->clear(pipe, PIPE_CLEAR_COLOR1, int_clear_color, ...);
This doesn't need any driver changes yet, because all drivers just use:
if (flags & PIPE_CLEAR_COLOR) ..
The drivers which support GL 3.0 will have to implement it properly though.
