Message:

remove LOG_EXEC() macro, use compile-time instrumentation for detailed kernel logging

• add more files to the INSTRUMENTED_SOURCES list in kernel/Makefile where instrumentation is safe (extra care must be taken not to enable instrumentation in functions where it would lead to an infinite cycle [e.g. print functions] and where resources are limited [e.g. temporary stack])
• even in files which are in the INSTRUMENTED_SOURCES list specific functions can be excluded from being instrumented via the attribute((no_instrument_function)) decoration
