2016-12-14kdbus: add connection, queue handling and message validation codeDaniel Mack
This patch adds code to create and destroy connections, to validate incoming messages and to maintain the queue of messages that are associated with a connection. Note that connection and queue have a 1:1 relation, the code is only split in two parts for cleaner separation and better readability.
