  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.

  Amend previous commit.  The problem was that when a socket was already open,
  open_sockets() did not count it as "good".  Having fixed this, revert to the
  previous behaviour of keeping the sockets open if auto_restart is on; this
  avoids having a brief window (until they are reopened) during which client
  connections are refused.

  Remove object from LRU list before freeing it; this does not entirely
  eliminate races between the LRU code and the expiry code, but it does
  make them a lot less likely.

  Assert that LRU_DiscardOne() returns 1, to avoid an unlikely but possible
  scenario where multiple clients each require different objects such that
  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
  cache) causing STV_alloc() to enter an infinite loop.
  
  This is not ideal - a better solution would be return NULL and have the
  caller deal with the problem, possibly by returning a 503 result, or by
  stalling the request for some time.

  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.
  
  Give sscanf the NUL it wants.

  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.
