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.

| 3844 | 6 This module provides **public** access to Prosodys |
| 7 [internal statistics][doc:statistics] trough the | |
| 8 [XEP-0039: Statistics Gathering] protocol. This is a simple protocol | |
| 9 that returns triplets of name, unit and value for each know statistic | |
| 10 collected by Prosody. The names used are the internal names assigned by | |
| 11 modules or statsmanager, names from the registry are **not** used. | |
| 12 | |
| 13 # Configuration | |
| 14 | |
| 15 Enabled as usual by adding to [`modules_enabled`][doc:modules_enabled]: | |
| 16 | |
| 17 ```lua | |
| 18 -- Enable Prosodys internal statistics gathering | |
| 19 statistics = "internal" | |
| 20 | |
| 21 -- and enable the module | |
| 22 modules_enabled = { | |
| 23 -- other modules | |
| 24 "stats39"; | |
| 25 } | |
| 26 ``` | |
| 27 | |
| 28 # Usage | |
| 29 | |
| 30 | |
| 31 ## Example | |
| 32 | |
| 33 Statistics can be queried from the XML console of clients that have one: | |
| 34 | |
| 35 ```xml | |
| 36 C: | |
| 37 <iq type="get" to="example.com" id="dTMERjt5"> | |
| 38 <query xmlns="http://jabber.org/protocol/stats"/> | |
| 39 </iq> | |
| 40 | |
| 41 S: | |
| 42 <iq type="result" to="example.com" id="dTMERjt5"> | |
| 43 <query xmlns="http://jabber.org/protocol/stats"> | |
