This change addresses a few issues in rip_entry_print_v2() and rip_print(): 1. In the case of Simple Password (RFC2453) authentication the last (16th) character of a password was never printed. Other password characters were printed regardless of existing isprint() test. 2. In the case of Cryptographic (RFC4822) authentication there were no details available for fixed-size auth header and variable-size auth trailer. 3. Depending on particular hash function used, a normal authentication trailer "RTE" may be 20 or more bytes long. Iteration over packet RTEs should stop once a trailer is decoded. Exact number of RTEs in a message cannot be told from message size any more. Test cases are added for Request and Response messages with Simple Password, Keyed-MD5, HMAC-SHA-1, HMAC-SHA-256, HMAC-SHA-384 and HMAC-SHA-512 authentication modes. Earlier test case is updated to match new "number of routes" output format.
