[DCCP]: Introduce DCCP_{BUG{_ON},CRIT} macros, use enum:8 for the ccid3 states
This patch tackles the following problem: * the ccid3_hc_{t,r}x_sock define ccid3hc{t,r}x_state as `u8', but in reality there can only be a few, pre-defined enum names * this necessitates addiditional checking for unexpected values which would otherwise be caught by the compiler Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
