[OpenAFS-Doc] New man page: vos_shadow

[Jason Edgecombe]

Put it in doc/man-pages/pod1. I've included some warnings about not
using this unless you're an expert.

Most bits were copied from vos_copy. I'm not sure if that lets me
relicense as BSD, but that's what I did.

vos_copy is also BSD. :) Thanks, committed.
