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.

vijay chadachan 5697f396f6 Adjusted the num_dl_sched > 3 while adapting DL MCS for DL grants 
- The DL MCS adapted based on the BLER for the minimum number of
DL(numd_sched) grants for the UE in the pre_configured number of frames.
The current threshold value is set to be >9 for 16 UE capacity.
- With increased number of UE to 32 and when all the UEs are DL data active
the num_dl_sched is not meeting the threshold value. Due to whcih the MCS
of all the UEs are stuck with MCS 10-12 in good channel condition.
- The threshold value is adjusted to support 32 UE capacity increase.

vijay chadachan 740bec4ac0 Fix max_sched_ues in DL/UL Scheduler to match MAX_DCI_CORESET 
- Added the limit as MAX_DCI_CORESET for max_sched_ues in DL/UL scheduler.
This is needed because gNB crashes when tested with 100MHz cell as the
scheduler tries to schedule 11 UEs in a slot and the DCI informaiton is
corrupted due to the limitation in NFAPI interface because of
MAX_DCI_CORESET size.

The memory allocation is increased to enable the periodic mac stats logging

Robert Schmidt a645e10ff5 F1AP: message encoders should no trigger GTP 
The F1AP message encoders and decoders should do only that, encoding and
decoding messages. For the actual logic handling, including set up and
teardown of bearers, we should use the handlers.

In this commit, delete GTP tunnel handling from encoders/decoders. For
the CU, this happens already in the CU-UP/E1 handlers in
cucp_cuup_handler.c.  For the DU, add it in the handlers in
mac_rrc_dl_handler.c.
