 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.
