Copyright waiver from Helios (fix for non-BSD copyright)

I have received the attached email from HELIOS Software GmbH giving us
permission to change the licensing of HELIOS-contributed software to our
project to the official BSD license.  (I am BCC'ing them.)

I think we should re-add the AIX files we removed from CVS yesterday,
and then remove the non-BSD HELIOS copyright from CVS HEAD and all back
branches.
