Hello osmith, Jenkins Builder, laforge, fixeria, daniel, dexter, 

I'd like you to reexamine a change. Please visit

    https://gerrit.osmocom.org/c/libosmo-sccp/+/25689

to look at the new patch set (#2).

Change subject: osmo_sccp_simple_client_on_ss7_id(): Allow set internally proper IPv4/v6 default hosts

osmo_sccp_simple_client_on_ss7_id(): Allow set internally proper IPv4/v6 default hosts

Allow user apps to relay the decision of proper default local/remote
hosts values to the library. Proper configuration of these addresses can
be quite cumbersome to get correctly, or confusing at least. That's due
to the multi-homing feature of SCTP where both IPv4 and IPv6 are
involved.

We were already doing this kind of automatic setup in
osmo_ss7_vty_go_parent(), where we do validations and assign addresses
based on IPv6 availability.
On the other hand, apps using osmo_sccp_simple_client_on_ss7_id() API
usually pass  "localhost" as default address. In Linux, when IPv6 is enabled
localhost is resolved as "::1", and "127.0.0.1" when IPv6 is disabled.

Let's instead allow apps to relay the setup to the lib, so same addresses
can be applied both during VTY command as well as if there was no VTY
setup at all.
