Message:

improve kernel function tracing

• add support for more generic kernel sources
• replace attribute((no_instrument_function)) with NO_TRACE macro (shorter and for future compatibility with different compilers)
• to be on the safe side, do not instrument most of the inline and static functions (plus some specific non-static functions)

collateral code cleanup (no change in functionality)
