Makes it possible to avoid copying or allocating in cases where DeliverNetworkPacket (rx)
needs to turn around and call WritePacket (tx) with its VectorisedView.
Also removes the restriction on having VectorisedViews with multiple views in the write path.

This CL does NDP link-address discovery for IPv6.

The previous use of non-blocking writes could result in corrupt PCAP files if a
partial write occurs. Using (*os.File).Write solves this problem by not
allowing partial writes. This change does not increase allocations (in one path
it actually reduces them), but does add additional copying.
