We can provide a generic QMP dispatch interface that high level 
languages can use.  Then they can do fancy dispatch, treat QErrors as 
exceptions, etc.

We just ought to also provide some simple C wrappers for all of the 
functions.  Yes, the C interface is inferior to the generic interface 
but that's fine.
