Message:

Configurable OCSP socket timeout

Stalled OCSP requests must time out after a while to prevent stalling
the server too much. However, if the timeout is too short requests may
fail with a slow OCSP responder or high latency network
connection. Using the new GnuTLSOCSPFailureTimeout parameter users can
adjust the timeout if necessary.

All macros defining default values for OCSP related times are now
collected in gnutls_ocsp.h.
