Set OPENSSL_NO_SSL_INTERN when compiling against OpenSSL 1.0.1

versions when internal structures are changed. Use API functions

never used by any released version of mod_ssl.

optionally modified by a module when the effective IP of the client
is not the same as the real IP of the client (such as a load balancer).

distinguish between the raw IP address of the connection and the effective
IP address of the request.
