Adding LLC-XID related modifications in LLC
With this commit the already existing XID mechanism has been
modified to suit the needs for the upcomming SNDCP-XID patches.
This commit should not break anything since it does not alter
the current behaviour (incoming XID is still just echoed, on
GMM-Reset a basic XID message is still echoed)
