Move the unordered library into 'branches' now that it has been accepted.

svn path=/; revision=42181
Actually, there are some things in the unordered code that aren't ready for
trunk, so I'll rename the branch and create another one to be added to trunk
later.

svn path=/; revision=42182
Use pre-review copy of unordered for trunk.

  Explicity use the classic locale in the case insensitive example. I could make
  the locale a member, but that would make the example longer. Also, this would be
  a good place to put a note about the need for constant function objects.
