mesa: in glReadBufer() set _NEW_BUFFERS, not _NEW_PIXEL
Since GL_READ_BUFFER is historically part of the gl_pixel_attrib group it made sense to signal changes with _NEW_PIXEL. But now with FBOs it's also part of the framebuffer state. Now _NEW_PIXEL strictly indicates pixels transfer state changes. This change avoids framebuffer state validation when any random bit of pixel-transfer state is set. DRI drivers updated too: don't check _NEW_COLOR when updating framebuffer state. I think that was just copied from the Xlib driver because we care about dither enable/disable state there.
