Until commit d74b2bd1, the PSS detection step size was 4, anyways. The PSS detection step size is a compromise between detection duration and accuracy. The most accurate detection step size would be 1, but this would lead to even longer initial sync time.

Changed Info to Debug because the logs are too much if large number of GSCN scans run concurrently. Print PSS correlation peak and average power of detected cells.

Till this commit, the UE gets the position of SSB in frequency from command line and does the syncronization by locating the SSB in time. It does this by generating a PSS time signal during initialization with the SSB offset given via command line. Then PSS detection is done by correlation. In this commit, the UE computes a list of GSCN in the current NR band that falls within the current bandwidth for the set center frequency. For each GSCN in the list, the UE starts a thread and performs the following: 1. Generate PSS time signal with SSB offset for current GSCN. 2. Detect PSS, SSS and decode PBCH (this step remains the same). After all threads finishes, the results are collected. For now, only the first detected PBCH is used to proceed further. So this PBCH is indicated to MAC and UE exits initial sync. Future work: The cell search can be standalone feature where the UE could scan for SSB in the entire NR band. This would require changing radio's frequency on the fly as the UE's bandwidth would not cover an entire NR band. The cell detection can futher be imporved by looking for SIB1 for each decoded PBCH.

Implement the #define variables required for synchronization: These variables include offset and payload size values that vary from the Uu interface, in relation to the PSS, SSS and PBCH elements. We also introduce the new sl_mode command line flag, which is used to switch between the Uu interface and SL interface. This will allow us to modify exisitng PSS and SSS functions, without copying complete 5G functions and only changing a few lines to support sidelink mode. Fixing formatting for softmodem-common.h

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.

Actually there was a bug in FO compensation which I overlooked in last commit.

While fixing bug in PSS index calculation in 334519d1, I made changes in FO calculation as well. This is not nedeed and caused the FO to misbehave. Hence, reverting it.
