the sum of the sizes of the objects is larger than the cache (or, in the
extreme case, one client requests an object which is larger than the

Fix child restart by always calling close_sockets() when the child dies;
otherwise open_sockets() fails, which causes start_child() to fail silently.

Furthermore, if open_sockets() fails and child_state is CH_DIED, it will
not be possible to start it manually later; therefore, set child_state
to CH_STOPPED when open_sockets() fails.

Note: it wouldn't hurt if open_sockets() were a little more talkative.

From the "What has the world come to ?" department:

It used to be that sscanf(3) would walk along the proffered string
and do what the format string was told, and as long as the format
terminated before the input string, the NUL termination was not
relevant.

Sometime in the last 20 years, sscanf started doing a strlen on the
passed argument changing this behaviour.

Add "regsub" support for string manipulation.

Notice this facility is subject to change!

"regsub" is short for regular expression substitution and it is probably
easiest to explain with some examples:

sub vcl_recv {
set req.url = regsub(req.url, "#.*", "");
}

This will replace the requests URL with the output of the regsub() function

regsub() takes three arguments: the string to be examined, a regular
expression and a replacement string.

In this case, everything after the first '#' is removed (replaced
with nothing).

The replacement string recognizes the following magic sequences:
& - insert everything matched by the regexp
$0 - ditto.
$1 - replace with the first submatch of the regexp
$2 - replace with the second submatch of the regexp
...
$9 - replace with the ninth submatch of the regexp

(The $0..$9 syntax was chosen over the \0...\9 syntax in order to avoid
a nightmare of escape characters in the VCL source code. Arguments and
suggestions are welcome).

A more advanced example:

set bereq.http.ClientIP = regsub(client.ip, "(.*):(.*)", "$2 $1");

The client.ip variable expands to IP:port number, for instance
127.0.0.1:54662

The regular expression "(.*):(.*)" results in the the following matches:
& + $0 "127.0.0.1:54662"
$1 "127.0.0.1"
$2 "54662"

So the replacement string "$2 $1" results in "54662 127.0.0.1"

And the completed header which is sent to the backend will look like:

"ClientIP: 54662 127.0.0.1"

An even more advanced example would be:

set bereq.http.magic = "Client IP = " regsub(client.ip, ":", " port = ");

Where we also exploint the string concatenation ability of the "set" statement.

The result string is built in the request workspace, so you may need
to increase the workspace size if you do a lot of regsub()'s.

Currently there is no decent error handling for running out of workspace.
