> This patch is in response to Thiru's feedback about the current C
> implementation. Thanks, Thiru! I appreciate the feedback.
> Previously, all instances of an Avro value contained class-specific data and
> methods (e.g. callbacks for reading, skipping and writing data). This is
> inefficient and unnecessary.
> This patch creates a per value class registry to hold all class-wide
> information.
> Moreover, this patch creates the framework necessary for support the Avro
> JSON import/export format. Each value class registers all supported data
> formats (named AVRO_BINARY_FORMAT and AVRO_JSON_IMPORT_EXPORT_FORMAT). The
> current JSON parser is a DOM-like parser which is really only suitable for
> process schema data. The callbacks registered in the value class registry
> will allow us to process JSON data in a SAX-link fashion moving forward.
