[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

Francisco Paisana eb370642ab verify cell selection observer is set before calling it 4 years ago
Francisco Paisana 7f8af023b8 added a callback that always gets triggered when the phy cell selection completes. This callback checks if cell selection failed, and if so, sets the rsrp of the selected cell to -infinity 4 years ago

Andre Puschmann eeb2b904aa ue,rach: fix failing RACH proc when Msg3 grant RNTI matches current CRNTI
this was preventing that the Temp-CRNTI used in the RAR to be identical
to the currently configured C-RNTI of the UE.

The issue simply was that the RACH procedure was declared successful too
early, even before the Msg3 UL grant was filled with the Msg3 content.

The patch moves the logic that detects the successful completion of
the RACH procedure below the Msg3 packing.

Andre Puschmann b616944a13 ue,rrc: fix security config during HO/reestablishment
we fix a number of very related issues for HO/reestablishment
in the success/error case:

* this patch removes the hard-coded check that intra-cell HO aren't
allowed. There are cases where eNBs use this method to update
the security context.

* the patch also fixes an issue after failed HO where the security context
of the source eNB should be used for the reestablishment.

* update security keys according to specs when mobilitycontrol
indicated change of key

Andre Puschmann 6827c2df21 rrc_meas: disable layer3 filtering until quantity config is received
the filter alpha was initialized to zero by default which causes an
issue because the first measurement for a cell can't be updated,
because the filtering function will always return the current value.

According to 36.331 Sec 5.5.3.2 Note 2, a k-value of 0 should turn
off filtering, which should be used as the default value until
an update is received from the network.

Francisco Paisana 13a5bfb525 - fix reestablishment reject transmission in the srsenb. For SRB0 SDUs, no RLC header is required, so we do not need to check in such case if there is enough space in the TB for the header.
- fix srsenb reestablishment check for UE context. The pci has to be accounted for the srsenb to understand that the UE trying to do reestablishment corresponds to one of its own

Francisco Paisana 97133894e6 the Ocs value used in the measReport triggering decision was not being set correctly. The enum of the cell individual offset in the measCfg was being cast to an int and stored. Instead what we want is to store the actual offset value using the ASN1 enum->number lookup table. 4 years ago

Andre Puschmann 624c8142ad ttcn3: refactor cell handling in SS
this rather large patch changes the way cells are handled in the SS.
It moves RLC and PDCP entities to the cell map of the SS, such that each cell
has its own entities. This allows to support HO operation, for example,
in which two cells need to send SRB messages.

It also extends most of the syssim interface to include the cell name
in all commands so they can be applied on the specified cell only.

Andre Puschmann 973de8f78d ttcn3_dut: block OS signals before starting log backend
this prevents the backend thread from handling the signals. they
are only handled by epoll running in the main thread.

Andre Puschmann 6dc7841369 epoll_helper: move code to block OS signals into own helper function
before epoll can handle signals, the calling thread needs to block
them. the blocking needs to happen before any other threads get
spawned so they inherit the mask.
