* Safer defaults for immutable znc config
I just lost all the options I configured in ZNC, because the mutable config was overwritten.
I accept any suggestions on the way to implement this, but overwriting a mutable config by default seems weird. If we want to do this, we should ensure that ZNC does not allow to edit the config via the webmin when cfg.mutable is false.
* Do not backup old config files.
There seems to be little need for backups if mutable becomes a voluntary opt-out.
* fixup
The current `remotes` option is a string option containing nullmailer remote
definitions. However, those definitions may contain secret credentials and
should therefore not be put world-readable in the nix store.
I added a `remotesFile` option, which allows to specify a path to the remotes
definition file instead. This way, the definitions can be kept outside of the
nix store with more secure file permissions.
We now wait for dhcpcd to acquire a lease but dhcpcd is restarted on
system activation. As wpa_supplicant is stopped while dhcpcd is
restarting a significant delay is introduced on systems with wireless
network connections only. This changes the wpa_supplicant service to
also be restarted together with dhcpcd in case both services were
changed.
The current version is broken:
- there's no `openFirewall` attribute directly in the `cfg` set
- the `port` option is an attribute of the `confOptions` set
I used the proper attribute for the firewall port and moved the `openFirewall`
option directly up to the `services.znc` set, as it's rather a general option
for the whole service than a znc-specific option (which are located inside the
`confOptions` set).
This introduces dependency cycles.
A network file system to be running is not required for a network
connection to be available.

* Grants enough privileges to the configured user so that it can run
mysqldump.
* Adds a nixos test.
* Use systemd timers instead of a cronjob (by @fadenb).
* Creates a new user for backups by default, instead of using mysql
user.
* Ensures that backup user has write permissions on backup location.
* Write backup to a temporary file before renaming so that a failed
backup won't overwrite the previous backup, and so that the backup
location will never contain a partial backup.
Breaking changes:
* Renamed period to calendar to reflect the change in how to
configure the backup time.
* A failed backup will no longer result in cron sending an e-mail --
users' monitoring systems must be updated.
Resolves#24728
