mod_smacks: Add future todo The vision: All the queueing and counting and session replacement logic in core, with mod_smacks only hooking this up to the XEP-0198 protocol.

mod_smacks: Only include max resumption time when resumption is activated

core.modulemanager: Load mod_smacks on Components Since it applies to s2s on Components as well as on VirtualHosts.

mod_smacks: Fix typos

mod_smacks: Fix error on shutdown if loaded on Component

mod_smacks: Fix typo (thanks codespell)

mod_smacks: Avoid log noise when a non-smacks session is closed

mod_smacks: Check if session was really sleeping before logging message It could have been resumed without going into hibernation first, i.e. when the client notices the disconnect before the server, or if it switches networks etc.

mod_smacks: Fix traceback when bouncing unacked stanzas Errors sent from handle_unacked_stanzas() should usually not be sent to the session itself, but if one is, it should not be queued.

mod_smacks: Fix duplicate sleep behavior when replacing a session Fixes that an extra watchdog was set, leaking the previous one, which went on to do behave as if the session times out.
