Sorry, I don't remember who but someone proposed to add the follow_symlinks
parameter in scandir()  directly. If the parameter is added to methods,
there is no such issue.

I like the compromise of adding an optional follow_symlinks to is_xxx() and
stat() method. No need for .lstat().

Again: remove any garantee about the cache in the definitions of methods,
instead copy the doc from os.path and os. Add a global remark saying that
most methods don't need any syscall in general, except for symlinks (with
follow_symlinks=True).
