A module is built against the system-installed libdpm-core.so and is responsible for being correct against it. Where it needs to act on the version it is running under, dpm_core_version() reports that and the module decides for itself. dpm_module_core_min() is removed. It was a declaration handed to the library to enforce on the module's behalf, and enforcement of that kind belongs nowhere in a library that routes and hosts. The contract is now three reserved symbols and load validation is two steps: the reserved symbols resolve, and the version and description probes return well-formed values. compare_versions had no remaining caller and is removed; parse_version stays for the well-formedness probe. The core_too_new fixture went with the handshake it existed to exercise.
