Message:

OCSP refresh mutex: Prevent parallel requests

Add a global mutex which a thread must hold before updating a cached
OCSP response. This avoids two threads updating the same response in
parallel. The impact of parallel updates may be small with the
experimental file-based mechanism, but an extra OCSP request over HTTP
would add a lot of overhead.

Note that the new 'gnutls-ocsp' mutex is a global mutex, not one per
virtual host, because a mutex must be registered in pre_config for the
Mutex directive to work.
