Add support files for using text from the POSIX specification in

FreeBSD manual pages:

- POSIX-copyright contains copyright text to be used in manual pages
  which has POSIX text inserted.
- deshallify.sh is a shell script which removes many of the ``shall''
  statements from the POSIX text and therefore making the text more
  readable.

Real work to make this happen by:	nectar, ru
