scripts: new log (#2493)
* added new `_log` function

With `_log`, the `_notify` method wa rendered obsolete. `_notify` was
not completely removed due to test failures in `check-for-changes.sh`.

The new `_log` function properly uses log levels such as `trace`,
`debug`, `info`, `warn` and `error`. It provides a cleaner solution
and renders `DMS_DEBUG` obsolete too (as only `_notify` depends on it).

* converted all helper script to new `_log` function

* converted all startup stacks to new `log` function

* `start-mailserver.sh` now uses new `_log` function

* final test and misc small script adjustments

* updated documentation
