Multicast sidelink data transmission from the On-net to the Off-net UE also works now in parallel with UE attachment to the EPC and UL/DL traffic

Sidelink synchronization works in parallel with UL/DL now. Connected synchref UE can attach to the network, send and receive UL/DL IP traffic and also transmit the SL synch signals.

Temporary hack to fix the memory leak issue that appears in pdcp list of the UE only for the Unicast sidelink case. It has to be properly fixed afterwards.

After new merge of sidelink with develop, UE attachment and ping work fine. Low PHR value monitored at the eNB side. Need to find the reason

Include SIB18-19 in a separate SI message (not the same with SIB23). Pending to create another separate message for SIB21.

EUTRA equivalent frequency band description corresponding to USA ISM 900 MHz band added to UE and eNB
