: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.

.window is how many of the latest polls we examine.
.threshold is how many must have succeeded for the backend to be healthy.

	.window = 40;
	.threshold = 30;
		// Thirty of the last fourty polls must have succeed.

	.threshold = 4;
		// The last four polls must have succeeded.

Default values:
	.window = 8;

When an -expect fails in varnishtest, loop for up to a second since stats sometimes takes a little while to update

We do not need a mutex for our list, all manipulation is from CLI thread.

Presently we only record th state of the last 64 tries to poll the
backend in a shift register, which can be show with the interrim
CLI command "debug.health":
