Therefore, printing QMP objects involves sorting the keys to have a predictable ordering in the iotests output. However, if we want to pretty-print QMP objects being sent to the QEMU process, we need to build the entire command before logging it. Ordinarily, this would then involve "arguments" being sorted above "execute", which would necessitate a rather ugly and harder-to-read change to many iotests outputs. To facilitate pretty-printing AND maintaining predictable output AND having "arguments" sort before "execute", add a custom sort function that takes a dictionary and recursively builds an OrderedDict that maintains the specific key order we wish to see in iotests output.

To have qmp_log use log's serialization, qmp_log will need to accept only qmp filters, not text filters. However, only a single caller of qmp_log actually requires any filters at all. I remove the default filter and add it explicitly to the caller in preparation for refactoring qmp_log to use rich filters instead. test 206 is amended to name the filter explicitly and the default is removed.

Add a qmp version of filter_testfiles and adjust the only caller using it for qmp_log to use the qmp version.
