1. Fixed tests bugs caf bug350 and bug352 failing in Debug mode due to errors in QA code (removing items from the map during iteration).
2. Debug output messages are ignored in parse.rules in heal and bugs group to avoid false failures in Debug mode after changes made for #23609 and last integration of new tests.
3. Test bugs moddata buc60654 removed as duplicate of bug143.
4. Test bugs moddata bug143 fixed to compare real values properly. New command checkreal added for comparing reals with tolerance.
6. Test bugs caf bug114 is fixed to avoid use of OS-specific commands (command meminfo is used instead). Command checktrend is used to check for possible memory leak.
Files parse.rules corrected (point 2 in bug description)
