per-directory-exclude: lazily read .gitignore files
Operations that walk directories or trees, which potentially need to consult the .gitignore files, used to always try to open the .gitignore file every time they entered a new directory, even when they ended up not needing to call excluded() function to see if a path in the directory is ignored. This was done by push/pop exclude_per_directory() functions that managed the data in a stack. This changes the directory walking API to remove the need to call these two functions. Instead, the directory walk data structure caches the data used by excluded() function the last time, and lazily reuses it as much as possible. Among the data the last check used, the ones from deeper directories that the path we are checking is outside are discarded, data from the common leading directories are reused, and then the directories between the common directory and the directory the path being checked is in are checked for .gitignore file. This is very similar to the way gitattributes are handled. This API change also fixes "ls-files -c -i", which called excluded() without setting up the gitignore data via the old push/pop functions.
