Security issue fixed:

  * 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).

  * 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).

    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.
  * spec: Remove useless %bcond visibility_hidden (is always ON in cmake)
