add sched_mode 3 - for PROFILING - no fork is done - everything runs in the same process - for easier valgrind mem leak checking
* add loglevel HASTO -> always logs to main file (for backward compatibility)
	* preparation for logsplit and suppression
* added new sched_mode (SCHED_MODE_PROFILE) - disables all fork() calls and runs all checks in single thread - for easier memcheck/valgrind etc...
	* do not use this in production
