The E1AP Setup Request contained the network configuration (IP address,
ports) as well as the actual E1AP Setup Request application data
(Supported PLMNs, ...). This has the drawbacks that
- The E1AP Setup Request is stored to retrieve IP addresses in the E1AP
module, which is confusing as the Setup Request, per standard, has no IP
info
- The CU-CP received an E1 Setup Request for configuration during start
up, but it did not actually receive such Setup Request, but merely the
IP configuration to set up the socket
This commit splits the E1AP Setup Request into a "real" Setup Request
for application data, and creates a new type e1ap_net_config_t to group
all IP configuration data. Further, a new ITTI message type
E1AP_REGISTER_REQ is introduced to group both types. What happens is
- RCconfig_NR_CU_E1() reads both E1AP application-level data and IP
configuration, as previously
- The data is sent to the CU-CP. It discards the E1AP Setup Request
data, and only uses the network configuration to set up the socket
- The data is sent to the CU-UP. It uses the network configuration to
connect to the CU-CP, and then sends the E1AP Setup Request to the
CU-CP.
Currently, the CU-CP still stores the Setup Request locally, which will
be changed in the next commit to send it to the RRC.
The DRBLists inside E1AP message are for E-UTRAN. We don't support that
with our CU-CP/UP yet, so remove it to reduce ambiguity and complexity.
For the same reason, we remove the CN Support, which for us is always
"NR".

This enables build_oai to detect if the output terminal supports colors.
If it does, it will use colors in its output. If it does not, it will
just print the text, without color codes, improving legibility.
PDU Length is as per SCF 222.10.02: The total length (in bytes) of the
PDU description and PDU data, without the padding bytes. From
TX_DATA.request we get 8 (2 bytes PDU_Length + 2 bytes PDU_Index + 4
bytes num_TLV ) and from each TLV we get 4 + value size ( 2 bytes tag +
2 bytes length + value size without pading)
Therefore, add function to compute PDU_length() value for
TX_Data.request, taking into account how many TLVs there are.
compute_PDU_length() does not rely on access to `nfapi_nr_pdu_t`.
Put it into nr_mac_common.c to avoid introducing dependencies.

- Remove calloc from convert_csirs_pdu function, change return value

- Set parameter pointer as const as it's not modified
- Remove cast to fapi_nr_dl_config_csirs_pdu_rel15_t in csi_rx.c as
ue->csirs_vars[gNB_id]->csirs_config_pdu is already of type
fapi_nr_dl_config_csirs_pdu_rel15_t.
- Remove casted parameter in call to convert_csirs_pdu and replace with
csirs_config_pdu obtained earlier from
ue->csirs_vars[gNB_id]->csirs_config_pdu.
