Title:
  snat_idx and FIP Rules may overlap

Status in neutron:
  Expired

Bug description:
  FIP rules in agent/l3/dvr_fip_ns.py are given the range:
  FIP_PR_START = 32768
  FIP_PR_END = FIP_PR_START + 40000

  And snat_idx in agent/l3/dvr_router.py used for ip rules as well is computed using:
              if snat_idx < 32768:
                  snat_idx = snat_idx + MASK_30

  So that the FIP rule range could overlap the snat_idx range in rare
  cases.

  The obvious solution is "if snat_idx <32768+40001"(I think) but
  there's probably a better solution than hard coding 40000
