mroute*: Make mr_table a common struct
Following previous changes to ip6mr, mr_table and mr6_table are basically the same [up to mr6_table having additional '6' suffixes to its variable names]. Move the common structure definition into a common header; This requires renaming all references in ip6mr to variables that had the distinct suffix.
