mod_firewall: Update user marks to store instantly via map store The original approach was to keep marks in memory only, and persist them at shutdown. That saves I/O, at the cost of potentially losing marks on an unclean shutdown. This change persists marks instantly, which may have some performance overhead but should be more "correct". It also splits the marking/unmarking into an event which may be watched or even fired by other modules.

Description
===========

This module measures the rate at which text messages are exchanged, and their
encryption status.

::: {.alert .alert-warning}
This module can leak information about your users’ behaviour to anyone who can
access these statistics, so avoid enabling it on a server with few users.
