+ (Beep_transport, tcp): Add hooks for TLS tuning profile.
-+ (Beep_session): Remove M_reset from the mode_t type.
++ (Beep_sasl): Cancel semantics are broken. If supplicant cancels, then
+ service MUST reset and wait for exchange to restart (or `Abort), and client
+ should restart the exchange on the same channel. The supplicant MUST send
+ a Beep_channel.M_close.t and start a new client channel if the next
+ exchange needs to use a different mechanism.
-+ (Beep_session): Incomplete.
-+ No support for SASL or TLS tuning profiles.
++ No support for TLS tuning profile.
