      Change param thread_pool_min to be the minimum number of threads per · 61a4f7de

      pool, and don't be so stingy with them: default to five.

Make sure we really do create the minimum complement of threads.

      NB: Be careful with -trunk, this is a quite intrusive change.

Continue the progress on synthetic/error pages

The default "guru meditation" is now generated from the vcl_error {}
function, which can be redefined to whatever suits your taste.

Techinical:

Add new vcl_error method and make variables available in it.

Fix a bug in "error" action, where the numeric argument would not get
interpreted correctly if it came from a variable like obj.status.

Forbid "error" action in vcl_deliver since vcl_error now goes to
vcl_deliver to send the error object.

Fix test v00001 to reflect this.

Move the obj->ws/http initialization to preallocation time to avoid
duplication.

Add read-only variable req.xid (a string!)

Add default guru meditation to default vcl.

Remove cache_synthetic.c which is now unecessary.

      Add a facility to constructing a synthetic object from VCL. · f2fb353a
      Poul-Henning Kamp authored 
      This is just the initial version and it doesn't quite work the way
we need it to yet, but the idea is to be able to say:

	sub vcl_fetch {
	    if (obj.status == 503) {
		synthetic {"
		    <HTML>
		    <H1>Sorry, could not contact the backend server</H1>
		    <P>
			Try again later.
		    </P>
		    <HR>
		    <PRE>
			URL: "}  req.url {"
			User Agnet: "} req.http.user-agent {"
		    </PRE>
		    </HTML>
		"};
	    }
	}

A new VCL syntactic element have been introduced to do this: "the
long string".   A long string is anything from {" to "}, newlines,
controlcharacters and all.  (Normal "..." strings cannot contain
control characters.

Technical details:

Don't NULL terminate string sequences in VRT context, we may have
NULL cropping up as a legal value if a header is missing, add the
magic "vrt_magic_string_end" for terminating string contactenation.
