This is a test-driver which will be able to drive low-level tests of
varnish functionalty.

The present code manages to parse the example testcase description,
more work to follow.

XXX: needs to be auto*'ed, right now it uses FreeBSD makefile syntax.

The parameter session_linger determines how many milliseconds the
workerthread waits to see if another request has arrived, before
handing the session over to the session herder.

If we manage to catch the next request this way, we save a number
of semi-expensive steps, if we hang around too long, the worker-thread
gets to goof off.

A relatively small sample of data from a live server, indicates
that 20% of all requests arrive within 50 msec of the previous
request and 50% within 100msec.

It is not clear at present how these timeintervals relate to client
RTT, or if they are systematically too high, due to the duration
of the detour over the herder.

There is a new line in varnishstat keeping track of how many times
this gamble succeeds.

Experimentation is encouraged.

structure, instead of whatever we actually bound to.  It is more informative
and intuitive.

Report the listen socket spec in the SessionOpen shm record.

Close listen sockets as soon as we have forked the child, this eliminated
a fd-leak when a socket was eliminated from listen_address while the child
ran.

Fix various potential problems related to not being able to bind to one
or more listen addresses.

Associate ascii representation addr/port strings with each listen
socket, already in the manager process.

Postpone listen(2) call until client is ready, to limit initial 
connection spike.

XXX: I still miss an unlisten(2).

Have the worker threads add themselves to the pool, while the hold the pool
lock anyway.

Collect stats per pool, and have the decimator aggregate over all pools
and into the shared memory counters.
