When we've run out of space in the output buffer to store more data, we
will call zlib_deflate with a NULL output buffer until we've consumed
remaining input.
When this happens, olen contains the size the output buffer would have
consumed iff we'd have had enough room.
This can later cause skb_over_panic when ppp_generic skb_put()s
the returned length.

This changes the copyright notices on the PPP code that I developed
in the late 1990s from being copyright The Australian National
University to copyright Paul Mackerras. I can do this as I have an
acknowledgement in writing from the Head of the Computer Science
Department at ANU (where I worked then) that ANU does not claim any
intellectual property in this code.
While I'm at it, change the copyright notice from BSD-style to
GNU GPL like the rest of the kernel.

Move the PPP drivers into drivers/net/ppp/ and make the
necessary Kconfig and Makefile changes.
