Hi all,

Here are some enhancements I made to the metadata verifiers.  The first
adds structure checking to the attr leaf verifier.  The next two look
for obviously invalid dirent and attr names before passing them up to
the VFS.  The fourth patch fixes some problems where we return EIO on
metadata corruption instead of EFSCORRUPTED.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
