This makes DMA buffer allocation in all layers take an array of possible modifiers to allocate using, or zero modifiers if implicit modifiers should be used. The format hard coding previously used is moved to the screen cast code, or in case of the (unused by default) shadow buffer buffers use the same format as the the CoglOnscreen. This also means the CoglDmaBufHandle and MetaDrmBuffer got taught how to distinguish between planes. It's mostly unused in practice, so rather untested.
