VCL programs, but in practice it didn't happen because we fired the
GC function VCL_Idle() after 5 seconds of silence on the CLI port and
the manager pings every three (by default).

Instead change the name of VCL_Idle() to VCL_Poll() and call it
before every CLI command, so that any query command will get an
up to date status.

more complicated than a single file can carry.

cache_backend_cfg.c now contains the configuration and selection of
backends and directors.

cache_backend.c contains the connection and request management against
backends.

It is possible to specify just the URL to be probed, or to specify the
entire HTTP request:

	backend b0 {
		.host = "127.0.0.1";
		.probe = {
			.url = "/test.jpg";
			.timeout = 224 ms;
		}
	}

	backend b1 {
		.host = "127.0.0.1";
		.probe = {
			# NB: \r\n automatically inserted after each string!
			.request =
			    "GET / HTTP/1.1"
			    "Host: www.foo.bar"
			    "Connection: close";
			.timeout = 0.3 s;
		}
	}

If the full request has not been completed within the timeout, the
backend will be set to down.

by another simple director, it would be too hard to explain why they
shared statistics and harder yet to make them not do so.
