PROTON-2558: Add make class operation to hide class details
The new operation is used by the bindings to create proton objects
without needing to know the details of the pn_class_t struct.
> Provide an API to create pn_class_t instances

> Project: Qpid Proton
> Issue Type: Sub-task
> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher
> Priority: Major
>
> The Proton bindings (for at least Python, C++ and ruby) need to create
> {{pn_class_t}} instances for various reasons. Currently the only way to do
> that is to use some macros in {{proton/object.h}} which create static const
> {{pn_class_t}} instances however this requires knowledge of the internals of
> the struct itself which means that it cannot be changed without breaking ABI.
> So shifting this to a dynamic API is necessary to hide the internals of
> {{{}pn_class_t{}}}. This is very slightly less efficient but only in the
> startup path so it really doesn't matter all that much!
