We're not binary compatible, so bump soname.  Closes: #293

will make at getting a backend connection.  By default it tries as many
times as it has members.

        backend default {
                .host = "127.0.0.1";
                .port = "9080";
                .max_connections = 100;
        }

will limit the simultaneous TCP connections to this backend to 100.

Stats counter backend_busy == "Backend connections too many" tells
how often we have hit this limit for a backend.

polled as unhealty.

This technically makes Varnish 2.0 "feature complete", but some further
polishing is to be expected.

First step in activating backend polling:  Do not attempt to open
connections to a unhealthy backend.

Fixed an error in the argument passing from the init script. Added some more info text to the stop action.

have the directors provide that.

Entirely a no-op, apart from a bugfix that just would screw
you even more (than "totally") if socket(2) should ever fail.

connect to, but a connection to a backend, this makes it possible
for the directors to choose another backend, if connection to the
first backend fails.

we actually need to get a filedescriptor to the backend.

This also makes it evident for vcl_pass{}, vcl_pipe{} and vcl_miss{}
if the client sent a Host: header or not.  Previously these functions
saw the default Host: header.

IANA has reserved the 198.18.0.0/24 network for Network Interconnect Device
Benchmark Testing which vaguely fits what we are doing.  Use that
instead of 127.0.0.2 since the latter works fine to bind to on Linux
(at least).

When testing synthetic error page caching, make sure we connect to
:9080 rather than the default :80 since the machine might well have an
httpd running already.

Don't look for umem on FreeBSD, which have dummy stub version for
dtrace or ZFS compatibility.

Generally restrict probes for Solaris specific stuff to when we
run on solaris, no need to make configure slower than it is.

Don't pretend we can get anywhere without poll(2) we use it for
lots of things:  Remove #if conditionals around poll-acceptor.

Sort a couple of lists, before they get too unsorted.

traffic fares.  Problems seen there could be caused by all sorts
of special circumstances (bad PHP, weird headers from client etc)
and is not indicative of the backends health.
