TAKE 902773 - new mkfs AG size code

[Nathan Scott <nathans@xxxxxxxxxxxxxxxxxxxxxxx>]

Rework the mkfs allocation group sizing algorithm, making better use
of the available bits.  This changes the maximum allocation group
size enforced by mkfs to be 1TB (from 4GB), which scales alot better
for very large filesystems.

cheers.
