dirstate: walk returns None for files that have a symlink in their path

Previously dirstate.walk would return a stat object for files in the dmap
that have a symlink to a directory in their path.  Now it will return None
to indicate that they are no longer considered part of the repository. This
currently only affects walks that traverse the entire directory tree (ex:
hg status) and not walks that only list the contents of the dmap (ex: hg diff).

In a situation like this:
  mkdir foo && touch foo/a && hg commit -Am "a"
  mv foo bar
  ln -s bar foo

'hg status' will now show '! foo/a', whereas before it incorrectly considered
'foo/a' to be unchanged.

In addition to making 'hg status' report the correct information, this will
allow callers to dirstate.walk to not have to detect symlinks themselves,
which can be very expensive.
