[genivi-dlt] [PATCH] Multithreaded DLT file parser

Hi all,

we'd like to propose a patch which speeds up parsing of DLT files.

The functions DltFileIndexer::indexFilter() and DltFileIndexer::indexDefaultFilter() will use a helper thread if filters and/or plugins are active to speed up DLT file loading.

Please see the attached Excel sheet for some numbers indicating the speed up.

As long as any filters or plugins are used, a time improvement is achieved by using an extra helper thread. Therefore, threading is only useful if at least one filter or plugin is active.

If no objections arise the patch will be integrated into master within 5 working days.
