Hello lynxis lazus, pespin, fixeria, laforge, Jenkins Builder,

I'd like you to do a code review. Please visit

    https://gerrit.osmocom.org/c/libosmo-sccp/+/19856

to review the following change.


Change subject: Revert "Introduce SS7 IPv6 support"
......................................................................

Revert "Introduce SS7 IPv6 support"

This reverts commit 0b39f2cf7bab5cf3924d8b0b753f41b5b0cabd25.

Reason for revert:

Breaks ttcn test suites (at least for osmo-bsc) with osmo-stp error log:
"MTP-TRANSFER.req for DPC 187: no route!"

The breakage is fixed by only reverting the NULL -> "localhost" change
back to NULL. But the commit log indicated a reason for this, so rather
reverting the entire commit for now.
