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.
Co-authored-by: Robert Schmidt <robert.schmidt@openairinterface.org>

The F1AP DU F1 Setup Request encoder made the sytem information
required, but it is optional. Handle correctly.

In NSA, we don't have SIB1. However, the DU system information requires
both MIB and SIB1, but is itself optional. So, in NSA, don't fill the DU
system information.

CU's TransactionID in F1SetupResponse didn't match Setup Request for
some DUs, so implement this correctly and answer with correct
transaction ID.

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.

gNB-DU System Information may be sent after setup to update the system
information, and the RRC can "do without". See next commit.

read_version() takes a version string in format "x.y.z" with x being
major, y minor, and z patch number. It transforms reads them into
separate numbers, and outputs in the correspondingly named variables.

  - e2_ran_func library divided into e2_ran_func_cuup (CU-UP only) and e2_ran_func_du_cucp_cuup (DU, CU, CU-CP and gNB-mono)
  - GTP SM is not yet implemented in CU-UP -> CU-UP doesn't store PDU session information
  - PDCP SM support for gNB-mono, CU and CU-UP
  - KPM SM support for all node types (DU, CU, CU-UP, CU-CP and gNB-mono)

 - update KPM available versions
 - bool return when reading Service Models
