chg: added assert when finalizing buffer string
fix: check buffer for null after an append unicode
fix: forgotten buffer check on tds result parse
fix: parse packet if ack is before pkt wl origin

If wl is started with seqA and response packet a previous packet (like
seqA - x), we have an underflow on sync_offset. Just parse packet at
once since we will probably won't have the matching packet.

chg: rpc: handle tcp fragment and add sun rpc ports
chg: rpc: restrain signature with assigned program name
chg: added debug logs in pkt_wait_list
chg: refactor previous ack tcp test
fix: mark parent as called if finalize has been called
fix: pkt_wl: proto_parse pkt on parse err to avoid ignoring packets
chg: added tests for tcp pkt reorder
chg: cifs: remove duplicated code
chg: test: return -1 on error for CHECK maccros
