Bartosz Podrygajlo 0161a1c4fd Optimization for unused symbols in NR UE 
After processing TX frequency domain data skip IFFT call for symbols that aren't
used, the time domain buffer is memset instead.

Bartosz Podrygajlo 55b5e04e8d Change alignment of temporary IDFT buffer in PHY_ofdm_mod 
Alignment of temporary IDFT buffer was changed to 64 bytes. This is in preparation
for possible use of different IDFT implementation which could use AVX-512, requiring
64-byte alignment.

Bartosz Podrygajlo 9e6c0c8c78 Fix unused code paths in PHY_ofdm_mod 
For completeness sake, unused CYCLIC_SUFFIX and NONE extension
types were fixed to match CYCLIC_PREFIX memcpy usage.

Bartosz Podrygajlo 1481d89dfd Optimize PHY_ofdm_mod CYCLIC_PREFIX in case of incidentally aligned pointers 
It seems that the cyclic prefix is in most cases a multiple of 512 samples.
This means that in most cases the idft output pointer is already aligned and
there is no need to perform an extra memcpy. This saves the memcpy time in
most cyclic prefix insertion cases.

Robert Schmidt 555a54f85e Add Sidelink (SL) carrier frequency 
1. Adding a "SL" frequency for Sidelink mode. The
   importance of this variable is to ensure that
   when we are in mode 1 (UE+UE+gNB), that the slot
   configuration and frequencies do not overlap. This
   SL frequency is important for rotation and allows
   us to utilize the OFDM modulation and demodulation
   functions that already exist in OAI.
2. Adding sl_mode to the command line for proper UE
   deployment when in SL mode. sl_mode can be set to 0,
   1, or 2. sl_mode 0 indicates no-Sidelink at all,
   mode 1 is gNB, UE, and UE (3GPP defines mode numbers).
   sl_mode 2 indicated UE to UE communications with no
   gNB at all.
3. New functions for calculating the carrier frequency
   for SL mode.

Melissa Elkadi 4dd579e042 int32_t to c16_t conversion 
This commit includes changes to the function
footprints for vaiours NR UE and gNB functions.
It does not updated the LTE code. For functions
shared by both LTE and 5G, we maintained the original
LTE footprint and argument structure.

Several of the simulators that use these functions
have been updated as well. The specific usage of these
functions which index into the int32_t buffers and
treat the first int16_t and the real and the second
as the complex should be modified in the near future.
