Modifying some printouts into the file.

Intermediate commit. Adding HARQ support for SIC receiver. Changes in dci_tools.c to map TB to CW in a proper way.
Enable different options for TB1 retransmissions. Needs further improvements.

Counting for the number of 2CWs or 1CW retransmissions.
Adding corresponding changes to the phy_scope.

2.Fixing modulation for TM2 in dlsch_modulation.c
The branch now passes dlsim tests.

Introduced >>1 shift in SIC modulation for 64QAM to avoid overflow.
Shift is then compensated in llr computation.

1. Introducing dlsch_16qam_llr_SIC.
2. New writing files format in file_output.c
3. Some comments addded.

small bugfix in dlsch_demodulation
shunted out TM3-7 specific DCI generation in scheduler to enable basic operation. more work needed.

+ small bug fix in dlsim related to sic cw.

2. Fixing confusion between dl_ch_rho2_ext and dl_ch_rho_ext[harq_pid][round].

1. in dlsim.c: now we check for the receiver type and, if SIC,  proceed through encoding, modulation, LLR compuattion and decoding
of the decoded TB0.
2. Implementing routines for vector-vector multiplication and vector-vector subtraction
3. Adding some printouts for debuging purposes.
4. New functions: modulation_SIC, dlsch_qpsk_llr_SIC
5. In phy_scope.c: changing llr plotting: now for the length of coded_bits_per_cw.

Still need to caliibrate shifts -J.

Fixing new modulation tables for TM4 and TM6. Now all modulation orders and combinations work and the maginutes are at  appropriate level.

Streams must have the same shift, otherwise error floor. O
This reverts commit dbf587a5.

  avg_1[0] = avg_1[0] + avg_1[1];
Diff per-layer shift

Undoing previos commit. Previous commit is kept to generate TM4 PCE AWGN plots with the right precoder.

To be reverted after.

  avg_0[0] = avg_0[0] + avg_0[1];
  avg_1[0] = avg_1[0] + avg_1[1];
  avg_0[0] = max (avg_0[0], avg_1[0]);
  avg_1[0] = avg_0[0];

avg_1[0] = max(avg_1[0],avg_1[1]);

avg_1[0] = max(avg_0[1],avg_1[1]); taking this into account in correlation.

2) Fixing bug in mrc_TM4 - removing loop over tx antennas.

Fixing bug in passing arguments to dlsch_dual_stream_correlation, introducing dlsch_dual_stream_correlation_opposite

Revert "Experimanetal change in dlsch_channel_commensation_TM34. Will not work for more than 2 antennas."

This reverts commit cbd30e62.

Testing.

Changing names of output files in dlsim respectiively.
