In bugzilla and users@ we keep receiving questions about
how to test the new restrictions imposed by HttpProtocolOptions.
Added some info about how to use openssl s_client properly
and the mod_dumpio's directives to debug (thanks to
Daniel Ferradal for this suggestion).

When using shared MPMs, `httpd -V` will perform a full configuration
check, which emits warnings when there is no defined ServerName.
Unfortunately the test suite does a -V check for every test section,
spamming the output with noise.

Work around this by just uncommenting the example ServerName in the test
config.

seems like a steady stream of comments/questions in this area.

When compiling against APR < 1.6, the actual error message was buried in

we're going to error out anyway.
