[NETLINK]: Generic netlink receive queue processor
Introduces netlink_run_queue() to handle the receive queue of a netlink socket in a generic way. Processes as much as there was in the queue upon entry and invokes a callback function for each netlink message found. The callback function may refuse a message by returning a negative error code but setting the error pointer to 0 in which case netlink_run_queue() will return with a qlen != 0.
