don't use %(banaction)s interpolation because it can be complex value (containing `[...]`), so would bother the action interpolation.

filter processing:
...
- avoid duplicates in "matches" (previously always added matches of pending failures to every next real failure, or nofail-helper recognized IP, now first failure only);
- several optimizations of merge mechanism (multi-line parsing);
fail2ban-regex: better output handling, extended with tag substitution (ex.: `-o 'fail <ip>, user <F-USER>: <msg>'`); consider a string containing new-line as multi-line log-excerpt (not as a single log-line)
filter.d/sshd.conf: introduced parameter `publickey` (allowing change behavior of "Failed publickey" failures):
- `nofail` (default) - consider failed publickey (legitimate users) as no failure (helper to get IP and user-name only)
- `invalid` - consider failed publickey for invalid users only;
- `any` - consider failed publickey for valid users too;
- `ignore` - ignore "Failed publickey ..." failures (don't consider failed publickey at all)

amend to d1b7e2b5fb2b389d04845369d7d29db65425dcf2: better output (as well as ignoring of pending lines) using `--out msg`;
filter.d/sshd.conf: don't forget mlf-cache on "disconnecting: too many authentication failures" - message does not have IP (must be followed by "closed [preauth]" to obtain host-IP).
