WIP: Add partial shrinking support to f2fs
allow 'safe' resizing leaving the metadata nearly unchanged.
Will likely need to adjust growing for the case where a fs
had previously shrunk without altering data, and the newly grown
fs would be smaller than the original. Probably makes sense to
case it out into metadata size changes, instead of fs size changes
