this fixes#3437. The check/requirement for target srate to be different
to current srate isn't needed, and in fact fails for 6 PRBs where both are
indentical always.
* Protect PHY SR signal management in a class
* Protect intra_freq_meas vector
* Protect cell and srate shared variables in thread-safe classes
* srsue,srsenb: include TSAN options header
* Protect ue_rnti_t and rnti scheduling windows behind thread-safe classes
* Protect access to state variable in sync_state
* Protect access to metrics configuration
* Protect access to is_pending_sr
* Protect access to UE prach worker
* Protect UE mux
* Avoid unlocking mutex twice
* Fix data races in RF/ZMQ
* Fix data races in intra_measure and PHY
* Fix minor data races in MAC
* Make TSAN default behaviour to not halt on error
* Fix blocking in intra cell measurement
* Address comments

races detected with TSAN, primarily the ue_sync object which isn't
thread-safe is accessed by all workers to set the CFO and by the
sync thread to receive samples (which read the CFO).
The patch introduces shadow variables that are updates from the
main thread before/after the sync is executed. The atomic shadow
variables can then be read from otherthreads without holding a
mutex, i.e. blocking the sync.
* Replaced UE logger in the ue class.
* Replaced loggers in the main phy class and prach.
* Replaced loggers in phy common and ta_control.
* Replace loggers in cc and sf workers.
* Replaced loggers in intra_measure, scell_recv, search, sfn_sync, sync.
* Remove last uses of the old loggers in the main phy class.
* Remove stray newline in logs.
* Replaced loggers in ue gw.
* - Started to replace loggers in the ue stack.
- Replaced loggers in usim and pcsc.
- Adapted nas and usim tests.
* Replace loggers in nas.
* Added missing log init calls in two previously modified tests.
* Replaced logger in nas idle procs.
* Replaced loggers in nas emm state.
* Replaced loggers in tft packet filter and adapted tft test.
* Replaced loggers in main RRC class.
* Replaced loggers in RRC cell.
* Replaced loggers in RRC meas.
* Replaced loggers in rrc procedures.
* Started logger replacement in MAC layer, more precisely in demux and dl_harq classes.
Been unable to inject loggers in construction for dl_tb_process due to very weird static assertions in the std::vector code being the type not constructible which is not true, so instead use the main MAC logger directly.
* Replaced loggers in mac mux class.
* Replaced loggers in mac pro_bsr.
* Replaced loggers in mac proc phr.
* Replaced loggers in mac proc SR and RA.
* Replace loggers in mac UL HARQ.
* Replaced loggers in main ue stack class.
* Fixed nas test crashing due to a null string.
* Ported mac_test to use the new loggers.
* Removed TTI reporting for the PHY log as the old logger did.
* Replaced loggers in UE phy tests.
* Configure loggers in nas_test.
* Replaced loggers in rrc_meas_test.
* Replaced loggers in rrc_reconfig_test.
* Added missing newline in tft_test.
* Fix compilation errors in TTCN3 tests.
* Fix linker error detected in CI and warning.
* Replaced loggers in TTCN3 tests.
* Fix a text replace error in some log messages.
* Remove trailing newlines from log entries.
* Remove old logger from rrc.
* Flush backend before printing the test status.
* - Fix compilation error from previous rebase.
- Remove trailing newlines from some missing log entries.
* Take into account CRS from neigbhour cells when measuring interference
* fix std::isnormal compilation
* Fixed compilation of test
* Address comments
* Remove unused overrides
* Make PHY non-blocking and fefactor HO procedure
* makes entire PHY non-blocking through command interface
* adds dedicated queue for cell_search/cell_select commands
* refactor HO procedure to run faster, in one stack cycle. Looks closer to the specs
* force ue to always apply SIB2 configuration during reestablishment
* Run update_measurements in all workers

The current TTI gap calculation assumes strict continuity
of radio time stamps, even when retuning, changing sample rate, etc.
This is certainly desireble but not necessaritly the case and may cause
issues when negative time gaps or too large gaps are detected and reported
to the stack.
this patch makes the assumption that valid TTI jumps are between 1ms
and 1s and that larger gaps are the result of screwed time-stamps
or too long radio operations.
* Use task id to track old background tasks in RA procedure
* Improve robustness against RF overflow in PHY
* Increase SNR out-of-sync threshold
* Do not change frequency if it's the same
* Increase sync priority
* Increase time to start receiving to reduce input buffer occupation
* Use scoped lock in sf_worker
this patch adds a buffer len paramter to the receive_samples() call
that protects the (also) provided buffer from overflowing.
currently each call to srslte_ue_sync_zerocopy() which then calls receive_samples()
relies on a buffer that is "big enough". But that buffer is sometimes
2 subframes, sometimes 3 or 5, sometimes has space for the maximum PRB size, sometimes
only for 6 PRBs (i.e. during cell search).
By extending the interface to pass the buffer size we can make sure that
only samples are received that actually fit inside the provided buffer.
