Robert Watson 8ed3828c3b Introduce a new bd_seesent flag to the BPF descriptor, indicating whether or 
not the current BPF device should report locally generated packets or not.
This allows sniffing applications to see only packets that are not generated
locally, which can be useful for debugging bridging problems, or other
situations where MAC addresses are not sufficient to identify locally
sourced packets.  Default to true for this flag, so as to provide existing
behavior by default.

Introduce two new ioctls, BIOCGSEESENT and BIOCSSEESENT, which may be used
to manipulate this flag from userland, given appropriate privilege.

Modify bpf.4 to document these two new ioctl arguments.
