I can already tell by the diffstat that I don't like this. We probably
don't need 3000 new lines of code for this, but we especially don't want
to duplicate nand_bbt.c. It won't take a lot of work to augment
nand_bbt.c to make it shareable. (I can whip that patch up if needed.)

I'll still take a look at the rest of the code eventually, but just
wanted to give my 2 cents up front.
