Add support for physical disk emulation?

[mirh]

In particular, the required information are already stored in the supported MDF images. So.. I guess it would just be about "exposing" them. Specifically:

• Media Physical Signature
• sub-channel data (already supported perhaps?)
• seek timings
• twin sectors displacement
• weak sectors

I think a good starting point might be this. Of course I'm not asking this to be specific to game backups, so no problems if something is still left out.

Thanks for the suggestion. We probably won't be able to allocate enough resources for this, but if anyone is willing to contribute a patch, we may consider it.
