Applied temporary fix to error code returned by pj_gethostbyname(). Under *nix, the error code is returned in h_errno, and the error string is reported by hstrerror(). But it is a bit too complex to support this for the moment, so we just return PJ_ERESOLVE for any failure returned by gethostbyname()
