Polish Jackson 3 support

- Improve Javadoc. - Suppress warnings for "removal". - Update copyright headers. - Migrate several tests from: - MappingJackson2MessageConverter to JacksonJsonMessageConverter - Jackson2JsonEncoder to JacksonJsonEncoder - Jackson2JsonDecoder to JacksonJsonDecoder - Jackson2SmileEncoder to JacksonSmileEncoder - Jackson2ObjectMapperBuilder to JsonMapper and XmlMapper - MappingJackson2JsonView to JacksonJsonView - MappingJackson2HttpMessageConverter to JacksonJsonHttpMessageConverter - MappingJackson2XmlHttpMessageConverter to JacksonXmlHttpMessageConverter
