Fix ".. has no member named ... compile error" by renaming apache con…

…n_rec

attributes

 - conn_rec attributes remote_ip and remote_addr were replaced by client_ip
 and client_addr once they have been renamed in Apache 2.4
 - a server_rec pointer must be passed to ap_log_error() since apache 2.4,
 therefore, a change was necessary at the ap_log_error log function.
 A null pointer has been passed for avoiding deeper changes at the function.
 - the smart pointer auto_ptr was replaced by unique_ptr once it was made
 deprecated in C++11 standard, it has been replaced by unique_ptr.
