PROTON-865: C++ reactor binding for proton.
This is a C++ interface to proton, providing an event-driven API similar to the
python reactive API.
Each of the proton "classes" such as pn_link_t, pn_connection_t etc. is
represented by a C++ "facade" class that provides the relevant member
functions. These classes take up no memory, they are actually pointers to the
proton C structs with some casting magic to translate C++ member function calls
into C function calls.
A C++ smart pointer, proton::counted_ptr, automates proton reference
counting. It can be converted automatically to standard C++ shared_ptr,
unique_ptr etc. with the expected semantics.
The goal is to provide very low overhead access to the proton C library with the
convenience and safety of C++. There is no additional memory allocation or
reference counting imposed by the C++ layer. It is possible to mix C and C++
code.
The C++ documentation includes a tutorial and examples similar to the python
tutorial/examples.

>
> This JIRA tracks initial work on a C++ binding to the Proton reactor event
> based model with an eye to providing an API very similar to the python
> client. As stated on the Proton list, the broad goals are:
> to make it easy to write simple programs
> natural to build out more complicated ones
> very similar API to the Python client
> lean and performant
> The initial introduction with accompanying HelloWorld can be found at
> https://github.com/apache/qpid-proton/pull/18
> Ongoing work is proceeding in my github account in branch cpp-work
> https://github.com/cliffjansen/qpid-proton/tree/cpp-work
> commit 1453f57ca3f446450ef654505548f1947cb7a0f1 adds listener support,
> exceptions and a logging interface.
> The initial implementation will provide no thread safety guarantees, but the
> bone structure should allow that to be added later with no API change. I
> still hold out hope of eventually allowing multiple threads processing
> separate connections concurrently.
