Title: [For discussion] Extract a FLOW signature from TCPv4

Ideally as many things as possible should implement this. I have in
mind:
* CONSOLEs
* VCHANs
* TCP connections
* TLS connections

Unfortunately the lower levels of the network stack don't quite fit this
pattern because they typically have:

* write (good)
* writev (good)
* listen ~one_cb ~two_cb ... ~n_cb (bad)

NB this is a backwards compatible change (unless adding 'FLOW' causes a namespace problem somewhere)
