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.
