dir_iterator_advance() is a large function with two nested loops. Let's improve its readability factoring out three functions and simplifying its mechanics. The refactored model will no longer depend on level.initialized and level.dir_state to keep track of the iteration state and will perform on a single loop. Also, dir_iterator_begin() currently does not check if the given string represents a valid directory path. Since the refactored model will have to stat() the given path at initialization, let's also check for this kind of error and make dir_iterator_begin() return NULL, on failures, with errno appropriately set. And add tests for this new behavior. Improve documentation at dir-iteration.h and code comments at dir-iterator.c to reflect the changes and eliminate possible ambiguities. Finally, adjust refs/files-backend.c to check for now possible dir_iterator_begin() failures.
