[REBASE] Make PHY non-blocking and fefactor HO procedure (#1753) 
* 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

Andre Puschmann 1e0c8ead4c srsue,sync: fix TTI gap calculation and reporting 
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.

Improve robustness in RF Overflow (#1124) 
* 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

Andre Puschmann c7343cf6d8 protect sf_buffer from overrun in receive_samples 
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.

Xavier Arteaga f8294fb9df SRSUE: RRC measurements refactor and more fixes 5 years ago
Ismael Gomez 52716f8716 Process HO complete in the background to avoid heap-after-use bug when PHY measurements are reported during a HO 
rrc_meas refactor. Need to split commit

Fix typo

Temporal commit

Apply rx_gain_offset to neighbour cell measurements

srsLTE: modify TESTASSERT Macro to follow codeline

SRSUE: prevent RRC from having serving cell in neighbour list

SRSUE: DL HARQ does not need Time Aligment Timer. UL is disabled using PUCCH resources release

SRSUE: extend intra-frequency to CA SCell

SRSUE: fix confusing/ambiguous code in the RRC measurements and fix concurrency issue

SRSUE: remove RRC measurement report triggers when measurements are modified or HO succesful

SRSUE: fix compilation issues and Reest SIB indexes

Fixes sync using incorrect cell configuration when search cell does not find a correct cell

Small refactor to remove measurement report triggers always after removing measurement

SRSUE: Removed SIC PSS from UE

SRSUE: fix inter-frequency reestablishment and added more traces

SRSUE: Fix compilation issue

therefore allows to pass it to the MAC for PCAP logging

Andre Puschmann 65f50cd7ba introduce new UE layer design 
- abstract UE object now consists of a radio, a PHY, and a stack layer
- add new stack abstraction layer that combines MAC, RLC, RRC, PDCP, NAS and GW
- PHY layer now has a single stack interface and does not talk to MAC and RRC seperatly
