5e34005571 qtest: remove qtest_qmp_receive_success 
The purpose of qtest_qmp_receive_success was mostly to process events
that arrived between the issueing of a command and the "return"
line from QMP.  This is now handled by the buffering of events
that libqtest performs automatically.

1e8a1fae74 test: Move qtests to a separate directory 
The tests directory itself is pretty overcrowded, and it's hard to
see which test belongs to which test subsystem (unit, qtest, ...).
Let's move the qtests to a separate folder for more clarity.
