Additions to QLA filter.

Browse Source 
MXS-848 (partially). The QLA-filter now has additional options
to control the printing.
1. "append"
This toggles append-mode, where the filter opens the log files in
update mode (if file already existed) and only adds text to the end.
2. "print_service"
This toggles writing the service name onto each row. Mostly useful
with the unified_file-setting.
3. "print_session"
This toggles writing the session number onto each row. Mostly useful
with the unified_file-setting.

Also, the filter now writes a header to the beginning of the file
when creating it.

The printing has been separated to its own helper-function, in case
more accurate control will be added in the future.
