libqtest: Remove qtest_qmp_discard_response() & friends

qtest_qmp_discard_response(...) is shorthand for
qobject_unref(qtest_qmp(...), except it's not actually shorter.
Moreover, the presence of these functions encourage sloppy testing.
Remove them from libqtest.  Add them as macros to the tests that use
them, with a TODO comment asking for cleanup.
