[PATCH v2 0/8] netfilter: kconfig symbol updates

[Yousong Zhou]

The series was based work by Tony Ambardar in GitHub pull request [1].
Many investigations were done by Tony annd many changes were done by me.
All errors are mine of course.

The work focused on the following aspects.

 - Use current config symbols when possible, instead of those retained
   for compat reasons
 - Many kconfig symbols for conntrack and nat functions are now bool
   without prompt, instead of previously being old tristate.  Version
   conditionals are added for old kernel versions and they are now in
   unset state in target config as these options can only be enabled
   when selected by others

v2 <- v1

 - Add a new patch to remove now non-existent kmod nf_nat_redirect as
   suggested by Adrian Schmutzler
 - Fix wording of "netfilter.mk: add version conditional around
   CONFIG_NF_NAT_PROTO_GRE"
