Plug-in consumers should not be required to open-code the name
of the plug-in library. Consumers should discover the library name
somehow, and adding a macro in the header that defines the API seems
like a straightforward approach.

We specify the library soname here because the soname must always
change when the API version number (JP_API_VERSION) is bumped.

Eventually JP_API_VERSION can be deprecated.
