We already have a function create_directories() which can create an entire tree, and remove() which can remove an empty directory, but we do not have remove_directories() which can remove an entire tree. This patch adds such a function. Because removing a directory tree can have dangerous consequences when the tree contains a directory symlink, the patch here updates the existing directory_iterator construct to optionally not follow symlinks (previously it would always follow symlinks). The delete algorithm uses this flag so that for symlinks, only the links are removed, and not the targets. On Windows this is implemented with SHFileOperation, which also does not recurse into symbolic links or junctions.
