Implements dd::Column_statistics.

Allocate a new object which can serve as a placeholder for the original object in the Dictionary_client's dropped registry.
Such object has the same keys as the original but has no other info and as result occupies less memory.

Re-establishes the state of *this by reading sdi information from the rapidjson DOM subobject provided.
Cross-references encountered within this object are tracked in sdictx, so that they can be updated when the entire object graph has been established.
rctx | stores book-keeping information for the deserialization process |
val | subobject of rapidjson DOM containing json representation of this object |

Converts *this into json.
Converts all member variables that are to be included in the sdi into json by transforming them appropriately and passing them to the rapidjson writer provided.
wctx | opaque context for data needed by serialization |
w | rapidjson writer which will perform conversion to json |
