This reduces the amount of glue code, because we don't need a void pointer or vtable within the structure. The only snag is that reftable_index_record contain a strbuf, so it cannot be zero-initialized. To address this, use reftable_new_record() to return fresh instance, given a record type. Since reftable_new_record() doesn't cause heap allocation anymore, it should be balanced with reftable_record_release() rather than reftable_record_destroy(). Thanks to Peff for the suggestion.
