More cleanup in preparation of ipfw relocation (no actual code change):

+ move ipfw and dummynet hooks declarations to raw_ip.c (definitions
  in ip_var.h) same as for most other global variables.
  This removes some dependencies from ip_input.c;

+ remove the IPFW_LOADED macro, just test ip_fw_chk_ptr directly;

+ remove the DUMMYNET_LOADED macro, just test ip_dn_io_ptr directly;

+ move ip_dn_ruledel_ptr to ip_fw2.c which is the only file using it;

To be merged together with rev 193497
