Hi, I will try to get into more details soon, but to keep you busy - the
first thing to start is to introduce new on-flash format version -
because you need more space in 'struct ubifs_branch'

Could you make a separate patch which adds new on-flash format and make
sure that new ubifs binaries can mount the old formats and work with
them. And that old ubifs binaries gracefully reject the new format.
