A single commit which deprecates the chunk table and mbox listing
modes. The chunk table can still be listed with para_afh(1), and the
mbox format was never really useful to begin with. The idea is to
remove support after 0.8.0 has been released.

<!--
- The chunk table and mbox listing modes of the ls server command
have been deprecated. They still work, but a warning is issued to
inform the user about the deprecated option.

* refs/heads/t/ls-l:
  server: Deprecate -l=c and -l=m of com_ls().
