WIP: Add "ring" message logger to review last N messages on /admin/logging

[zeripath]

Add a ring message logger to make it possible to see the last N log messages from the admin settings screen.

Very much WIP. UI not ready etc.

Current hacky way to add in the messages logger is to add:

[log]
MODE=console,messages; e.g. just append messages to current logging settings.
...

Just FYI: there was an old issue for this:

• Log option on admin area #15

What is clustering?

What about adding a method to get the current content of a named provider? It could be empty if the provider does not support that (smtp for instance). Or it could be the full content of the log file for the file provider. Or the content of the rotated list of messages for this new provider.

I think it means multiple gitea instances running off the same databases/cache/filesystem with traffic load-balanced between them. Any data specific to a single instance is problematic in such a case, it must be in a shared databases/cache/filesystem.
