updated llr scaling for PDCCH and PDSCH in TM5 initialized all newly allocated memory to 0 in new_eNB/UE_ulsch/dlsch and setting pointers to 0 after freeing memory in free_eNB/UE_ulsch/dlsch some small modifications related to EMOS (from the MU-MIMO measurement campaign) git-svn-id: http://svn.eurecom.fr/openair4G/trunk@4480 818b1a75-f10b-46b9-bf7c-635c3b92a50f
