- Procedure get_l_prime is modified
	- Single and double symbol DMRS are handled in Type A and Type B

Segmentation fault observed in case the address for mod_dmrs[dmrssymbol] is not 16byte aligned.

LocationandBandwidth adjusted according to the location of SSB and Controlresourceset 0
For example for 106RBs configuration files -
	- AbsoluteFrequencySSB = 641032 = RB43 (1032/24) - points to Subcarrier 0 of RB10 of SSB block
	- Hence SSB is located from RB33-RB53
	- Coresetzero sent in MIB is 0 which means offset 0, RBsize 24 from Start of SSB according to table 13.4 in Spec 38.213
	- InitialBWP should start from RB 33 (offset is 0 from SSB) and should be a size of minimum 24 RBs.
	- SLIV = 275 * (24-1) + 33 = 6358
Controlresourceset value wrongly configured to 12 , changed to 0 as sent in MIB.

Procedure fill_dmrs_mask is modified.
	- PDSCH Mapping Type B is supported
	- Modified according to sections 5.1.6.2 of Spec 38.214
	- Single and double symbol DMRS are handled in Type A and Type B

Mapping type according to the time domain allocation from DCI should be used to get the values of DMRS config
For sending sib1 - DCI FORMAT 1_0 will be used with SI_RNTI, UE should perform these actions
according to sections 5.1.6.2 of Spec 38.214

Additional DMRS set to pos2 in case of msg2 reception, msg3 transmission.

Mapping type B is added to RRC reconfig.
	- nr_dlsim updated to test typeA and typeB. Verified the changes.
	- RFSIM Validation of PDSCH Mapping TypeB  by changing timedomainallocation in configuration files.

Fix SA SIB1 segmentation fault

MR !1114 : sanitize v1
-bugs or dirty code fixed 
-add first version of a rf board calibration tool, not finished

MR !1094 : sim channels
Channel simulation: 
-command mode: to change noise, path loss, model (AWGN, RICE, ...) parameters channel simulation 
-channels separation: each channel can have a different model (for HO test for example) 
-a new build option --sanitize to compile all OAI with gcc --sanitize=address

MR !1034 : new gtpu
-New GTPU implementation

MR !1101 : develop-SA-CBRA
-Implementation of Contention Based Random Access procedures for 5G-NR Initial Access in SA mode (including contributions from BUPT and Fujitsu)
