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.

Enhancement 64 phy test

this branch (re)-introduces functionality that allows to run the eNB as a signal generator and the UE as a vector signal analyzer (old OPENAIR2=0). 
Tests mostly pass (as good as before).

Hotfix 81 oaisim 2

this branch fixes a few issues mainly with the oaisim testcases 
 - improved gain control for oaisim
 - updated testcase list options for oaisim
 - XFORMS now command line options for oaisim and unitary sims
 - build script improvements for sudo; HW=None and XFORMS=1 now default
 - fixed SNR calculation in abstraction mode

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

fixed mbmssim compilation issue
one more fix for build script sudo usage
