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.
