- Modified the expected error code in some of the test cases. The error
message is now issued by the JSON validator.
- Stop validation code being called if no application configuration is
given to validate.
- Change test mock code to check for specific calls, instead of number of
calls.
- Derive absolute paths for JSON schema files before loading them, which
seems to work better with the URI path resolution of the schema parser.
- Moved all common definitions from schema_app and schema_lib into a
separate definitions file.
- Changed the calling code to resolve multiple schema files correctly.
