[00/23] Convert ocfs2 to use folios

Message

Mark did a conversion of ocfs2 to use folios and sent it to me as a
giant patch for review ;-)

So I've redone it as individual patches, and credited Mark for the patches
where his code is substantially the same.  It's not a bad way to do it;
his patch had some bugs and my patches had some bugs.  Hopefully all
our bugs were different from each other.  And hopefully Mark likes all
the changes I made to his code!

The first patch is really independent of the rest, but a later patch
depends on it, so I don't want to send it separately.
