Start using the optimised, faster and more effective symlink/directory
cache. The previously used call:
has_symlink_leading_path(len, name);
should be identically with the following call to lstat_cache():
lstat_cache(len, name,
LSTAT_SYMLINK|LSTAT_DIR,
LSTAT_SYMLINK);
The primary reason for the new name of the function (instead of using
the old name and add 2 extra arguments), is that it is now more
general, for instance, it now also can cache the fact that a directory
does not exists.
