Various functions in log.h are only used by asserts, and there's enough assertion related stuff in macro.h to justify a separate header which also makes it easier to avoid circular dependencies. Let's introduce assert-util.h and an accompanying fundamental header and move all the assertion related stuff over there. PROJECT_FILE is moved over to macro.h.
