SDTv2 Release 2.4.0.1

#468 Regarding KEEP behaviour after PD Timeout
Modified the implementation such that in case 'KEEP' is selected as timeout behaviour, the last received data is still returned out of tlp_get().

#469 Receiving ECSP Status PD over multicast instead of unicast
Adding additional parameter in the tau_initEcspCtrl() API, which allows the user to pass (optionally) the multicast IP address over which the ECSP status telegram can be received.

MD telegram added for testing

#465 remove unused items in trdp_config.xsd

just to make lint happy ...
