Make 'traverse_tree()' use linked structure rather than 'const char *base'
This makes the calling convention a bit less obvious, but a lot more flexible. Instead of allocating and extending a new 'base' string, we just link the top-most name into a linked list of the 'info' structure when traversing a subdirectory, and we can generate the basename by following the list. Perhaps even more importantly, the linked list of info structures also gives us a place to naturally save off other information than just the directory name.
