John Snow f3efd12930 python/qmp: switch qmp-shell to AQMP
We have a replacement for async QMP, but it doesn't have feature parity
yet. For now, then, port the old tool onto the new backend.

John Snow 6e7751dc38 python/aqmp: rename AQMPError to QMPError
This is in preparation for renaming qemu.aqmp to qemu.qmp. I should have
done this from this from the very beginning, but it's a convenient time
to make sure this churn is taken care of.

John Snow 0e6bfd8b96 python/aqmp: copy type definitions from qmp
Copy the remaining type definitions from QMP into the qemu.aqmp.legacy
module. Now, users that require the legacy interface don't need to
import anything else but qemu.aqmp.legacy wrapper.

John Snow 3bc72e3aed python/aqmp: add __del__ method to legacy interface
asyncio can complain *very* loudly if you forget to back out of things
gracefully before the garbage collector starts destroying objects that
contain live references to asyncio Tasks.

The usual fix is just to remember to call aqmp.disconnect(), but for the
sake of the legacy wrapper and quick, one-off scripts where a graceful
shutdown is not necessarily of paramount imporance, add a courtesy
cleanup that will trigger prior to seeing screenfuls of confusing
asyncio tracebacks.

Note that we can't *always* save you from yourself; depending on when
the GC runs, you might just seriously be out of luck. The best we can do
in this case is to gently remind you to clean up after yourself.

(Still much better than multiple pages of incomprehensible python
warnings for the crime of forgetting to put your toys away.)

John Snow f122be6093 python/aqmp: Create sync QMP wrapper for iotests
This is a wrapper around the async QMPClient that mimics the old,
synchronous QEMUMonitorProtocol class. It is designed to be
interchangeable with the old implementation.

It does not, however, attempt to mimic Exception compatibility.
