ng_mppc(4): Bring netgraph(3) MPPC compression support.

Support for compression has been available from July 2007 but it
was never imported due to concerns with patents once held by
STAC/HiFn. The issues have clearly been resolved so bring it
in now.

Special thanks to Brett Glass for preserving the code and
pointing documentation for the expiration case.
