While implementing NRPPA-related F1AP messages, we remarked that
extension field "UL-AoA-ExtIEs" needs to be OPTIONAL (e.g., in NRPPA it
is optional in the OAI-compiled version), but it was not marked as such.
This later version 16.21.0 fixes this.
F1AP_LIB_FIND_IE() is used to look up elements in a list, but was
hitherto hardcoded to use "protocolIEs" as an intermediate struct. A
follow-up commit will use this macro where we don't have protocolIEs,
but "iE_Extensions". Hence, modify to make it work for that case (and
others) as well.
- encode all SI containers the encoding function gets (it's not the
encoding function's job to enforce semantics)

(Interface Management)")
During refactoring, the previously implemented NSSAI field of the cell
info structure was not written to F1AP ASN.1 structures anymore;
eq_f1ap_cell_info() also conveniently omitted the corresponding equality
check. Add this back so the CU can correctly receive the NSSAI in case
of F1 split operation.
Fixes: f278b00837 ("Add encoding/decoding library for F1AP Setup
Request (Interface Management) ")
Split out these functions, to be reused in a follow-up commit to
correctly have gNB-DU configuration update message working.
Change the return type copy_f1ap_served_cell_info(), to return the copy,
which IMO is more intuitive then passing target and source in
parentheses.
