## Description:
This update for libzypp, zypper fixes the following issues:
Security issue fixed:
* invalidating legacy libzypp unsigned-repository cache state [LIBZYPP-LEGACY-
CACHE-01] (bsc#1274625).
* hasCredentials() requires both username AND password to be non-empty
(bsc#1273242).
* GPG Key hints in repoindex.xml require at least a long id to allow auto-
import (bsc#1271730).
Non security issues fixed:
* Econf parser adds tags in drop-in files outside any section to [main]
(bsc#1272534).
* libzypp: X-ZYpp-AnonymousId header anomaly (bsc#1268321).
* Need zypper option to disable services to fix Dockerfile builds in OBS
(bsc#1257249).
* zypper loads repository data and installed packages prior to checking for
required arguments (bsc#1274091).
* Zypper patch doesn't give enough details about conflicts (bsc#1277790).
* dependency issue for package "python3-vsts-cd-manager" after starting the
upgrade (bsc#1261038).
Changes for libzypp:

* Replace popen cat/zcat with solv_xfopen for testcase loaders (fixes #749)
* zypp: Improve Testcase Loading for MCP Tools.
