These paths should call rxgk_put(gk) but they don't. In the
rxgk_construct_response() function the "goto error;" will free the
"response" skb as well calling rxgk_put() so that's a bonus.

Add more tracing for CHALLENGE and RESPONSE packets. Currently, rxrpc only
has client-relevant tracepoints (rx_challenge and tx_response), but add the
server-side ones too.
Further, record the service ID in the rx_challenge tracepoint as well.

Implement rekeying of connections with the RxGK security class. This
involves regenerating the keys with a different key number as part of the
input data after a certain amount of time or a certain amount of bytes
encrypted. Rekeying may be triggered by either end.
The LSW of the key number is inserted into the security-specific field in
the RX header, and we try and expand it to 32-bits to make it last longer.

Implement the basic parts of the yfs-rxgk security class (security index 6)
to support GSSAPI-negotiated security.
