svn diff of patch proposal. removes $log_templ and adds UCRV mail/amavis/debug/level

Popular statistic tools like amavis-logwatch fail, because they expect certain keywords in the log messages of amavis.

univention-antivir-mail provides a configuration file for amavisd-new (60-univention) that specifies a log template:

> # log both infected and noninfected messages (default):
> $log_templ = '[? %#V |[? %#F |[?%#D|Not-Delivered|Passed]|BANNED name/type (%F)]|INFECTED (%V)], #
> [?%o|(?)|<%o>] -> [<%R>|,][? %i ||, quarantine %i], Message-ID: %m, Hits: %c';

The problem is, that this overwrites the built-in log template. By now, amavis (at least the debian package) has a reasonable built-in log template that has evolved with recent releases, works well with amavis-logwatch and should fit our needs. Since I can't find a dependency on our custom log template, I recommend to simply remove it and rely on the built-in one.

Additionally, it would be great if the amavis log level would be configurable via UCR.

I'll attach a patch proposal.

Thank you for the patch.

Commit 63378 configures amavis to using the default logging template and adds a UCR variable mail/antivir/amavis/debug/level to set amavis log level (default=0).

Much of the really interesting data (like scan timing) is available when Amavis' $log_level is set to at least 2.
