[PULL,9/9] tests/libqtest: Make qmp_assert_success() independent from global_qtest

Commit Message

Thomas Huth Aug. 15, 2019, 5:59 p.m. UTC

The normal libqtest library functions should never depend on global_qtest.
Pass in the test state via parameter instead. And while we're at it,
also rename this function to qtest_qmp_assert_success() to make it clear
that it is part of libqtest.
