Fix a compile failure with recent OpenSSL and picky compilers

(e.g., OpenSSL 0.9.7a and xlc_r on AIX).

The OpenSSL info callback field changed recently from a generic
function pointer to a specific one, and ssl_callback_LogTracingState
wasn't quite right.

old:
ssl.h:        void (*info_callback)();

new:
ssl.h:        void (*info_callback)(const SSL *ssl,int type,int val);
