They're not needed; single underscore is enough to express intent that
these methods are "internal". double underscore is used as a weak name
mangling, but that isn't beneficial for us here.

calling "transaction( )" is pointless, but valid. Rework the parser to
allow this kind of invocation. This helps clean up exception handling
later by removing accidental breakages of the parser that aren't

We can invoke the shell history writing when we leave the QMPShell scope
instead of relying on atexit. Doing so may be preferable to avoid global
state being registered from within a class instead of from the
application logic directly.
Use QMP's context manager to hook this history saving at close time,
which gets invoked when we leave the context block.

* reuse code
* have a proper place for the module's own unittests
* apply a more consistent style
* generate documentation
