If VRT_error is called with reason==NULL, WSL() will eventually call
strlen(0), which will cause a SIGSEGV on (Open)Solaris.  Fix this by
checking if the reason is empty and just use (null) in that case.

This affects mainly pass'ed requests.

objhead lock, don't preallocate objects.

One unfortunate effect of this preallocation, only recently identified:

On systems with high number of worker threads and high hitrates, considerable
time could elapse between the preallocation of an object to a worker
thread and the use of that object.

This could make cache-misses use a much larger working set size than
really necessary.

I do not have access to any benchmarks that show a credible performance
difference, but reports are most welcome.

object allocation and insertion for later in cache_center.c

For now, do it right away in cache_center, before going to STP_MISS.

The original thinking was that only objects being prefetched were
relevant, but we take a more expansive view now.

majority of the cache_vrt_esi.c file is no longer "VRT" relevant.

Move the one function which is VRT to cache_vrt.c and rename
cache_vrt_esi.c to cache_esi.c

Move the vcl_fetch{} execution up between fetching the headers and the
body of the backend response.

This makes obj.* unavailable in vcl_fetch{} and replaces it with a
new beresp.* family of variables.

This paves the way for a lot of good stuff, such as streaming pass,
on-the-fly delivery of misses, storage selection based on headers
etc.

Cut Fetch() into two, FetchHdr() and FetchBody(), for now, just call

Added -x option to get XML output. As with the -1 option, it prints it once and quits, and you can choose what fields to include with the -f option. Example XML output is

<?xml version="1.0"?>
<varnishstat timestamp="2009-02-25T08:45:02">
	<stat>
		<name>client_req</name>
		<value>2656016</value>
		<description>Client requests received</description>
	</stat>
</varnishstat>

varnishstat.xsd contains the XML schema for the output.
