ofp-msgs: Split OFPRAW_OFPST_AGGREGATE_REQUEST

Split OFPRAW_OFPST_AGGREGATE_REQUEST into OpenFlow 1.0 and 1.1+
versions.

This should be sufficient to allow adding encoding and decoding of
Open Flow 1.1 and 1.2 Aggregate Stats Request messages.

Encoding and decoding of Open Flow 1.1 and 1.2 Aggregate Stats Response
messages works using the existing code without modification.
