args_type strings are such a crude tool...  I fear having two of them
just breeds inconsistencies.

There's a big difference between QMP and HMP: QMP has only named
parameters, HMP only positional parameters (type 'O' provides named
options within a positional parameter).  I figure the proper way to deal
with this is to define QMP parameters in a data structure (we need that
for self-documentation anyway), then define a mapping from HMP
positional parameters to QMP named parameters.
