Modified Files:
	syssrc/sys/netinet: tcp_input.c

Log Message:
In the tcp_input() path:
- Filter out multicast destinations explicitly for every incoming packet,
  not just SYNs.  Previously, non-SYN multicast destination would be
  filtered out as a side effect of PCB lookup.  Remove now redundant
  similar checks in the dropwithreset case and in syn_cache_add().
- Defer the TCP checksum until we know that we want to process the
  packet (i.e. have a non-CLOSED connection or a listen socket).
