Handler class abstract

Each command which the mysql protocol implements is handled with a _Handler object. A handler is created with the appropriate parameters when the command is invoked from the connection. The transport is then responsible for sending the request which the handler creates, and then parsing the result returned by the mysql server, either synchronously or asynchronously.
