This implements the solution to #25477. Any ``include`` directives
within state files can use multiple dot notation (influenced by Python
relative imports) to refer to a parent state.
This also implements the same functionality inside the stateconf
renderer
(http://docs.saltstack.com/en/latest/ref/renderers/all/salt.renderers.stateconf.html),
which supported relative includes, excludes, and prefixed states. This
PR expands on existing tests for stateconf.
This also updates the documentation accordingly.

* We try to import `OrderedDict` from the standard library, which is only available on python >= 2.7, if `ImportError` is raised we try to import it from `ordereddict`, a package available in PyPi. As a last resort, we provide our own implementation based on http://code.activestate.com/recipes/576669/.
* Update all code requiring `OrderDict` to use our compatible import module.
No more errors are shown because the configuration files are not readable, and in fact, the minion configuration can be use, unlike what was said in the comment.
- Added implicit ordering to pydsl.(turned on via __pydsl__.set(ordered=True))
- Fixed a KeyError bug in stateconf renderer that happens during id renaming.
- The stateconf renderer now generates a no-op start state as the
"first" state in a sls file.(enabled via -s)
- Made the stateconf renderer take high state input via the new -p
option, so we can pipe pydsl output into it.
- Added more and fixed some test cases for stateconf and pydsl.
