dccp: API to query the current TX/RX CCID
This provides function to query the current TX/RX CCID dynamically,
without reliance on the minisock value, using dynamic information
available in the currently loaded CCID module.
This query function is then used to
(a) provide the getsockopt part for getting/setting CCIDs via sockopts;
(b) replace the current test for "which CCID is in use" in probe.c.
