Log Message:
Make sure the mbufs in the input path (only the parts which we are going
to modify in the AH case) are writable/non-shared.
This addresses PR kern/33162 by Jeff Rizzo, and replaces the insufficient
patch from that time by a radical solution.
(The PR's problem had been worked around by rev.1.3 of xennetback_xenbus.c,
so it needs a network driver modification to reproduce it.)
Being here, clarify a bit of ipcomp -- uncompression is done in-place,
the header must be removed explicitly.
