- Sin and Cos values are obtained from a table with a resolution of
  100.
- dlsim is updated to use this table for phase noise.

- fixed channel compensation by choosing most recent DMRS symbol ina
  slot
- Removed code to find nearest DMRS symbol for channle compensation
- Updated TBS calculation in DLSIM
- Added debug prints in PTRS CPE estimation for DMRS symbol

- -U 2 0 [0-2], can be used to update DMRS configurations
- update check for additional position 3 in dlsch decoding

- Added PTRS extraction and estimation for DL
- Added processing for whole slot wrt PTRS estimates
- DLSIM is updated to used -T flag to enable PTRS
- DMRS compensated signal is further compensated with PTRS estimation

also added a log message for DCI generation in MAC

Created two dci_pdu's to hold dci configuration for UL and DL DCI.
This wasn't a problem before as only one DCI was scheduled.

-To avoid including the whole x2 libraries for the corresponding executables

The name NR_UE_list_t is misleading: beyond being a simple "list", this
structure carries all/most UE-related MAC information. If at all, it is
a container for multiple lists. The next commit introduces a
NR_UE_list_t structure that organizes UEs in lists such that it is
easier to go through the UEs.

Maybe not the right way to do.
To be checked.

- added some descriptions to the code
- fixed hardcoded factors
- removed commented out and unused code
- phy_procedures_nrUE_RX: removed unused do_pdcch_flag
- updated LTE naming to 5G

implementation of missing symbol-based rotation for NR modulation/demodulation (Section 5.3 38.211). Tested with unitary simulators (ulsim/dlsim).
To be tested with gNB testbench and rfsimlator

additional 50% speed improvement with SIMD vectors

this fixed dlsch crc fails

decoding performance degraded. still some issue to be solved.

This reverts commit 17a1a554.
