mod_c2s: Fire pre-closing event regardless of connected state With mod_smacks, a session can outlive the connection, so whether the event is fired should not hinge on whether the session is connected or not. Helps mod_smacks remove some state.

mod_smacks: Remove references to connection on hibernation Still having the connection on the session may cause unintentional behavior, such as the session being treated as if connected, even tho the connection has been closed.

mod_smacks: Add more logging

mod_smacks: Remove useless delay in requesting ack on resumption Was this the last place using the delay? Nice!

mod_smacks: Fix to not wait for acks from before a resumption Otherwise it can get stuck waiting indefinitely for an ack that made it notice the connection was stale.

mod_smacks: Split log messages for when an old session exists in storage Non-existent did not seem entirely accurate for this case

mod_smacks: Bounce unacked stanzas on shutdown

mod_smacks: Preserve counter values on shutdown

mod_smacks: Simplify access to local user sessions Less to type if per chance the next commit also wants to access sessions.

mod_smacks: Cancel hibernation when session is closed To ensure that if a session is replaced after it has gone into hibernation, it does not come back and cause trouble for the new session (see previous commit).
