Adding OCSP Stapling support to mosquitto, so that the TLS client side
requests the certificate status and checks it.
This code uses the OpenSSL-based OCSP implementation and is somewhat
based on the libcurl code for OCSP stapling.

The WITH_* flags are not handed over to the C++ wrapper, instead it relies on
the actual library to check status.
