sebres 309a1cb337 restore timeout for ipset-based actions: on some systems ipset created without default timeout may cause "Kernel error received: Unknown error -1" (gh-1994);
thus new option `default-timeout` introduced (because of dynamical bantime in 0.10, it cannot be used here).

Serg G. Brester 4f63180611
Avoid injection using quotes after `auth` command;
Added non-greedy fallback for quoted something (with lookahead simulated possessive greedy catch of non-quoted parts `[^"]*(?=")`).
Note that because host-info's are hereafter (with foreign input in-between), we would not use greedy or non-greedy catch-alls (`.*` or `.*?`) here (preventing performance losses).

Serg G. Brester f59df2e156
Avoid any injecting on protocol (e. g. tries using camel-case)
The phrase "AUTH command used when not advertised" is precise enough as anchor here, so prevent by any foreign-input (any auth protocol error).

Peter Nowee aa158ac05f
Exim failregex: Include lower/mixed case AUTH
When reporting the error `AUTH command used when not advertised`, Exim
starts with `SMTP protocol error in "........."`. Here, Exim logs the
SMTP command as it was provided by the connecting client.
https://github.com/Exim/exim/blob/exim-4_89+fixes/src/src/smtp_in.c#L2850

According to RFC 5321 (SMTP) "[..] a command verb [..] MAY be encoded
in upper case, lower case, or any mixture of upper and lower case with
no impact on its meaning."
https://tools.ietf.org/html/rfc5321#section-2.4

Lower case `auth login` brute-force attempts were seen in the wild and
were not caught by the current failregex.

This commit makes the failregex case-insensitive for the `AUTH`
command, so that lower case (`auth`) or mixed case (`aUtH`) now also
match. The failregex was already case-insensitive for the command
arguments (e.g. `AUTH login` already matched).

  * disconnected before auth was ready

dovecot: Match also when user field is empty
Commit 5678d08 of 2016-11-26 changed:

    ( user=<\S*>,)?

to:

    ( user=<[^>]+>,)?

The change from `*` (zero or more times) to `+` (one or more times) may
not have been intended. It will miss lines containing, for example:

    Aborted login (tried to use disallowed plaintext auth): user=<>

This commit reverts the `+` back to `*`.

sebres c21b4e4d56 [ban-time-incr] prolong ban, dynamic bantime, etc.:
- dynamic bantime: introduces new action-tag `<bantime>` corresponds to the current ban-time of the ticket;
  Note: because it is dynamic, it should be normally removed from `jail.conf` (resp. `jail.local`).
- introduced new action command `actionprolong`, used for prolongation of the timeout (ban-time of the ticket);
- removed default `timeout` from `actionstart` of several actions;
- faster and safer function escapeTag (replacement at once in one run, '\n' and '\r' escaped also);
