Changeset 94430e6 in mod_gnutls for test/tests/27_OCSP_server/ocsp.conf

Test suite: Run a separate Apache instance for the OCSP responder

This change will be needed to cache OCSP responses on start (and
schedule) instead of when needed. An OCSP responder in the same Apache
instance won't be ready while the mod_gnutls post_config hook is
executing.

The changes to lock file handling included in this patch mean that
most parts of the test framework won't need to check which locking
method (if any) is used, they can just pass a lock file which is then
used for flock or PID file checks depending on ./configure results.
