Make audit_path more stringent.

The following properties of a path are now checked for:

    - under top-level .hg
    - starts at the root of a windows drive
    - contains ".."
    - traverses a symlink (e.g. a/symlink_here/b)
    - inside a nested repository

If any of these is true, the path is rejected.

The check for traversing a symlink is arguably stricter than necessary;
perhaps we should be checking for symlinks that point outside the
repository.

% should fail
abort: path contains illegal component: .hg/00changelog.i
adding a/a
% should fail
abort: path 'b/b' traverses symbolic link 'b'
% should succeed
% should still fail - maybe
abort: path 'b/b' traverses symbolic link 'b'
