Robert Schmidt 66c3b7d192 Break coding_defs.h dependency on logging module 
coding_defs.h included defs_common.h, which pulls in many dependencies,
e.g., the logging module, which pulls in T. However, it does not use
anything of this. So remove, and include stdbool.h instead (because bool
is used in coding_defs.h.

nr_polar_defs.h relied on some includes done in coding_defs. Use
includes for pthreads and SIMD to define types that are used in
nr_polar_defs.h.

Ahmed Hussein aca390e63f Fixed repeating CRC NOK for 7 times, as well as CRC NOK occuring a lot more than CRC OK 
- changed Mdlharq to Mlimit when comparing with the round number
- Not incrementing the HARQ round in case of err_flag = 1, until HARQ is implemented
- Changed MAX_LDPC_ITERATIONS to 5 from 4 (provided better performance)

Thomas Schlichter 268d1c8d17 Fix order of DLSCH deinterleaving and rate matching 
On the gNB side tha data are first rate-matched and then interleaved.
So on the UE side, the received LLRs have to be deinterleaved first before rate-matching.

This significantly improved the performance, especially for MCS values > 3.
