Robert Schmidt 8f2e98a475 Upgrade F1AP to version 16.21.0 
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.

Robert Schmidt da915d21e0 Add F1AP UE context setup request message enc/dec + test 
Reintroduce separate message types to simplify the encoding/decoding,
including shorter names.  The old types will be removed once everything
has been migrated to the new encoder/decoder, which should ensure that
everything is properly migrated to the unit-tested encoder/decoders.

Also, for each type of F1 message (F1 UE context setup request,
response, modification request, ...) introduce a separate type to avoid
to mistakenly use wrong fields, which can lead to bugs. In this regard,
the DL PDCP SN bit size in the DRB-ToBeSetup list of the UE context
setup request is optional, as it will also be used in the UE context
modification request DRB SetupMod list (which avoids quite some code
duplication). The encoder checks that this IE is present, though.

Robert Schmidt 3a4440a99c Generalize F1AP_LIB_FIND_IE() to work with list container 
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.

Robert Schmidt 9f0373e051 F1AP lib: introduce macros to simplify implementation 
Introduce generic _F1_CHECK_EXP(), which is like the macros for checking
values (_F1_EQ_CHECK_INT() etc). Reuse the same for introducing
_F1_EQ_CHECK_OPTIONAL_IE that will be used to write the check for
optional fields more concisely.

CP_OPT_BYTE_ARRAY() FREE_OPT_BYTE_ARRAY() are macros to wrap handling of
optional byte arrays.

_F1_MALLOC() simplifies allocations and is similar to asn1cCallocOne(),
but provided to avoid confusion (since more than ASN.1 structures will
use it).

All will be used in the following commits.

Update the test so it would catch that bug. Check in eq_() that both
gNB_DU_IDs would be present, or not, using xor.

Robert Schmidt 2cc3f3bcac Fix: write NSSAI info of F1AP Cell Info struct 
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.

  Request (Interface Management) ")

Robert Schmidt ed876a53b2 F1: refactor out served_cell_info/du system info 
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.
