I'd like to start refactoring the messages send from nfcd. The problems for current message format are: 1. General Response is used to represent the response of WriteNDEF, makeReadOnly and Format requests. The problem is gecko needs to keep track of the last requests to know how to process this 'General Response' to Web application. 2. The type of the message is represented in 4 octets, and response code starts from 1000, and notification starts from 2000. I'd like to make it easier to make them both start from 0, and use the MSB to differentiate this message is response or notification.
