Log Message:
devel/rpc2: 2.7 -> 2.10
  New in 2.10:
  * AES-CCM-16 was incorrectly named AES-CCM-12.
  * AES-CCM checksum validation always failed when the final block was partial.
  New in 2.9:
  * Send busy responses on new but not yet enabled connections.
  * Make sure we wake up threads waiting for binding to complete.
  * Clean up mrpc2_SendReliably, it sometimes exited too early and ignored the
    overall timebomb timer.
  * Precompute retransmission intervals.
  New in 2.8:
  * Simplified retransmission interval calculation.
  * Do not wait for the full RPC2 timeout when receiving a busy response.
  * Unify rpc2 & sftp retransmission counters.
  * Fixed client-to-server sftp transfer failures.
  * PBKDF check would trigger unnecessary warnings depending on clock
    granularity.
