: Separate protocol states into general/specific

[DCCP]: Separate protocol states into general/specific

This prepares a separation of DCCP protocol states into
* those which have a generalisation as `stream' states and
* those which are specific to DCCP and do not generalise well.
For this purpose, the existing TCP_MAX_STATES is inserted as separator; everything between TCP_MAX_STATES and DCCP_MAX_STATES is private to DCCP.
