RLC has timers. We need to keep track of time. We chose to not use
realtime but 'processing time'. That is we send a tick to RLC for every
subframe when it is processed by the softmodem. Before this commit we
used to increase time in the function mac_rlc_status_ind which is called
for every subframe in the eNB, but not in the gNB (at least not in the
current gNB). So we need another way to keep track of time.

The function gNB_dlsch_ulsch_scheduler is called for every slot. It seems
to be the perfect candidate to send a tick to RLC for every subframe. We
take care of subcarrier spacing to send every subframe (one subframe is
always 1ms), not every slot (slot duration depends on subcarrier spacing).

It may not be the best solution. To be revised if needed.

Note: the UE has not been fixed. Some modification is needed for the UE
too, most probably.

Create a temporary rrc_eNB_ue_context_t when it can't be obtained from
current RRC state:
- if UE was not attached to current eNB
- when RRCConnectionReestablishmentRequest has a wrong encoding
- in all other cases when ue_context_p can't be obtained.

I had to remove the Msg2 transmission in phytest mode, which was present in branch 'benetel_integration'.
This caused following assertion:

Assertion (Foffset <= Ncb) failed!
In nr_rate_matching_ldpc() /home/sli/sudas-demonstrator/openair1/PHY/CODING/nr_rate_matching.c:411
Foffset 6492 > Ncb 924

Check the provided MCS index according to the specified table.
Some tables go up to MCS index 27, others up to MCS index 28.
If the MCS index exceeds the allowed limit, assume max. MCS.

- To enable PTRS use -T flag followed by 3 integers
- Example: ./nr_ulsim -T 2 0 2
- 1st Value is the list of arguments -> e.g. 2
- 2nd Value is for L_PTRS{0,1,2}     -> e.g. 0
- 3rd Value is for K_PTRS{2,4}       -> e.g. 2

removed AssertFatal in nr_ue_mac_procedures.c for nr_dlsim HARQ tests. For some unknown reason there are occasion 0 SDUs sent up to MAC which causes failure.

This commit contains work done by Eurecom and by Benetel.

Set n_dmrs_cdm_groups = 1 for now.
Should be fixed accordingly to TS 38.214 section 5.1.6.2
using tables 7.3.1.2.2-1, 7.3.1.2.2-2, 7.3.1.2.2-3, 7.3.1.2.2-4 of TS 38.212

- bad values in asn1_utils.c (copy/paste from 4g)
- remove hardcoded values (t_reassembly, sn_field_length)
- some cleanup
