        src/sys/net/npf: npf.h npf_handler.c npf_inet.c

Log Message:
Declare NPC_FMTERR, and use it to kick malformed packets. Several sanity
checks are added in IPv6; after we see the first IPPROTO_FRAGMENT header,
we are allowed to fail to advance, otherwise we kick the packet.

Sent on tech-net@ a few days ago, no response, but I'm committing it now
anyway.
