Estimate the threshold by simple averaging of mismatched bits of all detected DCI.

1.Changes to support multi slot parallel processing
2.Changes to run rfsimulator without multi-threading

This reverts commit 85e1c34c.

This reverts commit 0280c083.

1. Changed FIFO types to threadsafe to ensure order of execution
2. Changed RB_NB_TH to 1 because PUCCH have some issues when running 2 slots in parallel (race). Dont know exactly where it happens.

Created separate job for PDSCH processing so that its exectued in the right order in rfsimulator mode.

1. RX PBCH slot n
2. RX PDCCH slot n
3. Start TX PUSCH in parallel for slot n+6
4. RX PDSCH slot n
5. Join PUSCH
6. TX PUCCH slot n+6

when signal quality drops. when cmd line option used ue goes back to sync mode

thread1: RX
thread2: TX

this slightly cleans up nr_initial_sync() and UE_thread()

- removed commented out code
- improved logging in UL channel estimation
- minor fixes according to OAI coding guidelines
- moving fetching TDD configuration parameters in nr-ue.c only in TDD case

- missing check on duplex mode before fetching the TDD period
- missing flags configuration for FDD mode

Enabling more numerology combinations and 100 MHz support with 3/4 sampling for USRP X300/X310, too.

Reverted commit e0b1f612
removed a merge conflict error

Removed the hardcoding of fixed tdd and replaced with tdd config from mac configuration

I removed this from places where I felt it shouldn't be. Not sure why was it there in the first place.
To be reviewed.

- moved fill_dl_indication to phy procedures
- introduced a new function to fill the RX indication
- replaced redundant configuration code with the fill functions
- extended the function to fill the rx indication
- handling different dl pdus types
- cleanup of redundant code

- skipping RA procedures when MAC is disabled
- added mac_enabled flag that allows to disable RA and TA at UE from CL

- removed unused arguments to phy functions
- removed irrelevant conditions on UE run mode
- replaced hardcoded param with PHY UE stored value

- focus: defs_nr_UE.h, nr-ue.c, phy_procedures_nr_ue.c, nr_init_ue.c
- removed long-time commented out code
- replaced hardcoded params
- removed unnecessary header inclusions
