add directory to views for files that lack specified metadata
* view: New field?=glob and ?tag syntax that includes a directory "_"
  in the view for files that do not have the specified metadata set.
* Added annex.viewunsetdirectory git config to change the name of the
  "_" directory in a view.

When in a view using the new syntax, old git-annex will fail to parse the
view log. It errors with "Not in a view.", which is not ideal. But that
only affects view commands.

annex.viewunsetdirectory is included in the View for a couple of reasons.
One is to avoid needing to warn the user that it should not be changed when
in a view, since that would confuse git-annex. Another reason is that it
helped with plumbing the value through to some pure functions.

annex.viewunsetdirectory is actually mangled the same as any other view
directory. So if it's configured to something like "N/A", there won't be
multiple levels of directories, which would also confuse git-annex.
