Robert Schmidt e3747ab592 Check if Msg3 start&length can be accommodated in mixed slot 
Prior to this commit, it might happen that the gNB used TDA 0 (Start 0
len 13) for mixed slot, in which case the UE could not send msg3
(because a mixed slot has less than 13 symbols).

Robert Schmidt e6e25275ed Bugfix: make preamble_list an array 
- It is only a couple of bytes
- It hid a bug: if two preambles, L1_nr_prach_procedures() overwrote the
  preamble of the first with the second one

Robert Schmidt 0e2c9e8ebb Do not reduce RACH.ind count in loop 
if we reduce, we will never do all rach indications. Go one-by-one
instead.

Robert Schmidt defc97ec16 check Msg2 allocation frame/slot in DL scheduler 
Move decision of Msg2 allocation time instant from instance we receive
RA indication (only containing preamble time information) to actual RA
scheduler (containing current DL slot time). This has the advantage:

- if Msg2 cannot be sent, we might try in a later slot
- no timing-based problems were a RACH.indication FAPI message might
  come late, we calculate a Msg2 frame/slot, but this instant has
  already passed in the DL scheduler
- no assumption about slot_ahead (an L1 constant)

The previous code calculated and verified an SSB index; I am not sure
this code is correct or used. I leave the function
ssb_index_from_prach() (hence the gcc attribute), but remove any checks.
Similarly, the beam association list might be wrong. I deleted the
corresponding code.

  so store it

Robert Schmidt e0b31be148 Request release for UEs if DU disconnects 
38.473 section 8.2.3.1 says that upon F1 Setup Request, UE associated
signalling should be erased. In this commit, we trigger a release of all
UEs that were still connected to a DU when we received the SCTP
shutdown, i.e., when the DU disconnects.

Robert Schmidt 1e8f194d11 Only release UE in PDCP if in E1 
Explanations: see #706. TLDR: the RRC code calls nr_pdcp_remove_ue(), so
we should not call it in the E1 handler if we do not use split mode.

Romain Beurdouche 6cf2ab2a15 feat(phy-test): disable CQI and RSRP evaluation when running in phy-test mode 
In phy-test, the scheduler has a hardcoded UE allocation; if CQI and RSRP
are not evaluated, there is no change in the scheduler function. Also,
this avoids misleading error messages if no UE is connected.
