rgw: decouple object name from index representation

We can't have a direct mapping between the object name to the way we
index it in the bucket index. Have rgw_obj provide different
representations appropriately and use the proper ones where needed.
Introduce the instance element which will be used to refer to versioned
objects.

rgw, cls_rgw: various datastructures use new rgw_obj_key

Instead of using a string for referencing object's index key, use a
rgw_obj_key structure that's also references the object's instance.

rgw: clean up some locator use

We don't use locators anymore. New objects are always created having the
locator equals to the object name. Don't allow this to happen through
magic, just get rid of code that is setting the locator. Legacy objects
should continue to work as we'll still decode the locator, and set it on
the ioctx where needed.
