For silly reasons, pathlib's generic implementation of `walk()` currently resides in `glob._Globber`. This commit moves it into `pathlib._abc.PathBase.walk()` where it really belongs, and makes `pathlib.Path.walk()` call though to `os.walk()`. Symlink handling is a little different between the two `walk()` implementations when `followlinks=False`. In `pathlib` it means never following symlinks, not even for distinguishing between files and directories. In `os` it means never *walking* into symlinks, including any symlinks created by the user between iterations. We smooth over these differences with a private sentinel - `os._walk_symlinks_as_files` - that enables the pathlib behaviour.
