enhancements.

libzypp :

Security issues fixed :

  - CVE-2017-7435, CVE-2017-7436, CVE-2017-9269: Fix GPG
    check workflows, mainly for unsigned repositories and
    packages. (bsc#1045735, bsc#1038984)

Bug fixes :

  - Re-probe on refresh if the repository type changes.
    (bsc#1048315)

  - Propagate proper error code to DownloadProgressReport.
    (bsc#1047785)

  - Allow to trigger an appdata refresh unconditionally.
    (bsc#1009745)

  - Support custom repo variables defined in
    /etc/zypp/vars.d.

  - Adapt loop mounting of ISO images. (bsc#1038132,
    bsc#1033236)

  - Fix potential crash if repository has no baseurl.
    (bsc#1043218)

zypper :

  - Adapt download callback to report and handle unsigned
    packages. (bsc#1038984)

  - Report missing/optional files as 'not found' rather than
    'error'. (bsc#1047785)

  - Document support for custom repository variables defined
    in /etc/zypp/vars.d.

  - Emphasize that it depends on how fast PackageKit will
    respond to a 'quit' request sent if PK blocks package
    management.
