- CU-CP replying to the CU-UP with a Setup Failure message in case of unsuccessfull E1 Setup Request
- message is decoded by the CU-UP, and stops the process
This commit removes nr_rrc_mac_config_req_ue_logicalChannelBearer and handles configuration of logical channel bearers at MAC in nr_rrc_mac_config_req_cg.
This also avoids to configure LCs before resetting them again nr_rrc_mac_config_req_cg().
RRC Version is a required IE. Hence, implement the encoder and decoder
for this message. At the DU and CU, read the RRC Version we use and fill
the corresponding field.

For LiteOn DU, we do not receive the MIB/SIB1 in the F1 Setup Request.
This is not a problem in itself, but it might happen that certain
procedures are executed without MIB/SIB1. Check for it and handle
appropriately:
- During normal connection establishment, we might not be able to
calculate measurement config
- During reestablishment, we might not be able to calculate ARFCN SSB
and cannot do reestablishment; do RRC setup instead.
MR-2401 changed the argument to the init_nrUE_standalone_thread
to be zero instead of the ue_id_g. This causes every port to be
opened for multiple UEs to have the same value, therefore only
allowing one UE to be connected to the proxy. If the ue_id_g
global is an issue, we should open a new ticket for a proper fix.
When setting up bearer(s) through F1, the corresponding F1 message has
QoS fields for the DRB(s) to be set up, as well as for all flows
associated to this DRB. In this commit, set the DRB QoS field to be
equal to the first flow (it is unclear/unspecified how it should be set
up, based on the flows), which was not set before and therefore
contained unitialized data.
The F1 module uses this data, and in split mode, F1 message generation
failed due to uninitialized data.
We reuse RRC UE IDs at the RRC. Previous to this commit, we did not
release a UE at the CU-CP's PDCP (for SRBs). Thus, when reconnecting a
UE, the PDCP might not be in a good state, since we did not release the
previous PDCP UE context.
