Merge from vendor branch: update libpcap to 1.2.1.

MFC after: 2 weeks

Incorporate vendor commit ecdc5c0a7f7591a7cd4a:

In userland, sign extend the offset for JA instructions.

We currently use that to implement "ip6 protochain", and "pc" might be
wider than "pc->k", in which case we need to arrange that "pc->k" be
sign-extended, by casting it to bpf_int32.

Merge libpcap-1.1.1.

Revert previous commit that commented out some bpf functions.
Unconstify arguments of bpf_image(), bpf_filter() and bpf_dump(). This
is needed because some ports rely heavely on these arguments (some of
them even roll out their own implemenentations of bpf_dump).
