[DCCP]: 48-bit sequence number arithmetic
This patch * organizes the sequence arithmetic functions into one corner of dccp.h * performs a small modification of dccp_set_seqno to make it more widely reusable (now it is safe to use any number, since it performs modulo-2^48 assignment) * adds functions and generic macros for 48-bit sequence arithmetic: --48 bit complement --modulo-48 addition and modulo-48 subtraction --dccp_inc_seqno now a special case of add48 Constants renamed following a suggestion by Arnaldo.
