* remotes/huth-gitlab/tags/pull-request-2019-09-05-v2:
  gitlab-ci.yml: Install libattr-devel and libcap-devel to test virtio-9p
  qemu-doc: Do not hard-code the name of the QEMU binary
  tests/vm: Take the J=x setting into account for the vm-boot-ssh targets, too
  tests/libqtest: Use libqtest-single.h in tests that require global_qtest
  tests/libqtest: Move global_test wrapper function into a separate header
  tests: Remove unnecessary global_qtest references
  tests/libqos: Replace clock_step with qtest_clock_step in virtio code
  tests/libqos/e1000e: Make e1000e libqos functions independent from global_qtest
  tests/migration: Do not use functions anymore that rely on global_qtest
