ceph: add helpers for converting names for userland presentation

Define a new ceph_fname struct that we can use to carry information
about encrypted dentry names. Add helpers for working with these
objects, including ceph_fname_to_usr which formats an encrypted filename
for userland presentation.

[ xiubli: fix resulting name length check -- neither name_len nor
  ctext_len should exceed NAME_MAX ]
