change getaddrinfo() implementation to match GLibc.

the issue is that the BSD implementation doesn't accept a call like:

  getaddrinfo(SERVER_NAME, "9999", NULL, &res);

because if will reject a numerical string in the second parameter if no hints are explicitely
provided. This technically doesn't violate POSIX but might make porting Linux software a bit
difficult. For more details see:

also comment debugging printf() calls which shouldn't be there.
