I've added this code to the joel branch. But please, test this and other
UBI merge candidates with all the UBI debugging checks enabled as well.
Similar to UBIFS.

Well, I mean, I am willing to merge this feature upstream as soon as it
is in good shape, even if your crypto code is never merged. So testing
with debugging enabled should be done. For various small patches you
send which will land in the joel branch - I do not care much - test with
debugging enabled just sometimes.

Anyway, this patch is in "joel", once the whole features is there, I'll
move it to "master". So you could give this feature more priority for
now.
