[Minor] configwizard: really use LOCAL_CONFDIR

Deal with `Connection` and `Host` headers on proxying

[Feature] Allow to add templates to redis history prefix

Issue: #4793
Closes: #4793

[WebUI] Show pass-through module in History

[Minor] Move server selection logic to common.js

[Rework] Breaking: Do not report module as action

in the /history response since we have the `passthrough_module` key
for that purpose.

While that might be handy in some situations,
mixing actions and module names is confusing in general.

[Feature] Add extraction type for `from` maps

Attribute name: `extract_from`. Possible values:

* `default` - try smtp, if not exists try mime
* `mime` - check mime only
* `smtp` - check smtp only
* `both` - try to match both

* [Fix] Fix headers insertion in the ordered list
* [Fix] Fix learn error propagation
* [Fix] Fix learning with long prefixes
* [Fix] Fix potential double free by expclicitly zeroing pointers
* [Fix] Fix storing of the bayes tokens
* [Fix] Use short comments rather than long one

[Minor] rbl: fix warning

[Test] statistics: per-user

Issue: #4786
Closes: #4786

[Fix] Replace comment types

Rspamd fails to start with Lua-5.1 because long comment does not allow
nesting, see [1]. This change replaces it to short comments in order to
fix the issue but preserves this part as comment in docs.
