Deadwood snapshot update

I've just uploaded a second Deadwood snapshot for today:

• Server fail sent to TCP client if no upstream servers are reachable
• If handle_noreply has a value of 0, TCP connection closed if no upstream servers are available; Documentation updated to note this behavior
• NOCACHE option removed; we'll keep this in Deadwood 2.3, which is the Deadwood version to use on embedded systems.
• SQA tests updated; maxprocs test disabled because it's too flakey (Todo: make this test reliable and consistent)
• Program compiles and runs in Windows

It can be downloaded at the usual place
