Make the varnish accept address just use a random free TCP port.

Fix a couple of tests where we need to know the port number.

On 32 bit systems, it may be necessary to tweak this down to get high
numbers of worker threads squeezed into the address-space.

I have no idea how much stack-space a worker thread normally uses, so
no guidance is given, and we default to the system default.

Previously we stored the esi-metadata in the object workspace, but since we
are trying to make that a snug fit and we cannot preestimate how much space
ESI parsing will need, this no longer works.

Instead parse the ESI metadata into the workers workspace and when
done, allocate a storage object and move it all into that.

Beware that this may increase the memory cost for ESI objects by the stevedores
granularity.

We no longer use POSIX style regexes, but rather PCRE regexes.  This
introduces a hard dependency on libpcre.

Test suite passes, but only lightly tested.

The regex functions are in its own source file to make it easy to
change the decision if somebody wants to use non-PCRE for some reason.

Previously, trying to build from SVN without xsltproc installed would
get you errors like:

  --xinclude -o changes-2.0.1.html changes-2.0.1.xml
  --xinclude:No such file or directory

which is quite confusing.

We now rather just skip the docs completely if we can't find any
xsltproc.  If we actually do need to rebuild the docs (which should
only happen when running make dist), we error out with a useful error
message.

Move the objindex pointer and length to the segment table, having it
