dccp ccid-2: Separate internals of Ack Vectors from option-parsing code

This patch
 * separates Ack Vector housekeeping code from option-insertion code;
 * shifts option-specific code from ackvec.c into options.c;
 * introduces a dedicated routine to take care of the Ack Vector records;
 * simplifies the dccp_ackvec_insert_avr() routine: the BUG_ON was redundant, 
   since the list is automatically arranged in descending order of ack_seqno.
