The undefined logic is complex and has lots of magic on it. Implement it, using the same algorithm we have at get_abi.pl. Yet, some tweaks to optimize performance and to make the code simpler were added here: - at the perl version, the tree graph had loops, so we had to use BFS to traverse it. On this version, the graph is a tree, so, it simplifies the what group for sysfs aliases; - the logic which splits regular expressions into subgroups was re-written to make it faster; - it may optionally use multiple processes to search for symbol matches; - it has some additional debug levels.
