We are now able to select how apache should log accesses. These
modes are:

* default: as you would use it
* semianonym: no ips are logged for CustomLog, ErrorLog still logs
              ips
* anonym: no ips are logged for CustomLog, ErrorLog is sent to
          /dev/null
* nologs: all logs are sent to /dev/null

run_gid_name should per default be the same as the group for the
sftponly user. However, as can now set that one, we should be detect
if a groupname is set and use that one for the run_gid_name and not
as by default the $name.

- take uid_name out of itk, as $real_uid_name is used in non-tik
  defines as well
- fix the auto name, should be without _run
