remove remaining bits of osmo-bsc_nat
osmo-bsc_nat is too heavily tied into legacy SCCPlite code, as it
is not using libosmo-sigtran/osmo_ss7 so far. It's also full of
customer-specific code and it's shared use of some libbsc code here
has been complicating osmo-bsc development.
The current plan is to continue to use osmo-bsc_nat from openbsc.git
for those legacy users that need it, and not use osmo-bsc_nat in
new 3GPP AoIP setups. Should we ever get a strong demand for an AoIP
based bsc_nat, we can still revisit this later.
