* _F1_EQ_CHECK_GENERIC can be used to check the equality of two different members of F1AP structs
and return `false` if the condition is not met.
When the condition fails, the macros will print a debug message to the standard error stream,
including the function name, line number, and the provided format string and arguments.
Add a new target f1ap_lib that groups F1AP ASN.1 encoding&decoding for
messages defined f1ap_messages_types.h. The objective is to, for each
F1AP message,
- add encoder&decoder (similar to what already exists, but without
mandatory message sending afterwards)
- eq_X() function that checks two messages for equality (to be used
mostly in tests)
- cp_X() function that deep-copies a message, e.g., to be used when
sending ITTI messages, instead of manual copying done currently
- free_X() function that frees the memory associated to a memory, to
avoid memory leaks.
Each message will be tested, notably that encoding&decoding as well as
copying yield identical messages.
The actual message encoding & decoding, tests, and their use will be
done in the forthcoming commits.
The currently used type does not cover all possibilities. While we don't
encode&decode them, it might still be good to be able to express it, so
introduce the new type.

* num_SI is the size of the list of gNB-CU System Information messages
* the new struct member is an array, sized after the maximum nb
of SIB types, which contains the SI container, the container length
and the SIB type
The previously used net_ip_address_t type is limited to some bytes, but
the CU name might be longer. Use char * to allow longer DNS names.
Also, this type separates IPv4/v6, which is not necessary, as it is now
handled by the same C API (getaddrinfo()), since !2635.

Before this bug fix, when using F1, we get this warning:
Constraint validation failed: LCID: constraint failed (/home/richie/openairinterface5g/cmake_targets/ran_build/build/openair2/F1AP/MESSAGES/F1AP_LCID.c:30)
This is because (1) we don't actually store the LCID, then (2) we did
not put it into the F1 ASN.1 structures. Fix both, to make this warning
disappear.
To actually print the full error message, increase the error buffer
size. Also, for the future, to avoid guessing, print ASN.1 XML when we
encounter a failed constraint validation.
It can happen that SCTP communication is simply lost, e.g.
[SCTP] SCTP_ASSOC_CHANGE to SCTP_COMM_LOST
[SCTP] sctp_recvmsg (fd 104, len -1 ): Connection reset by peer:104
The previous code only handled the SHUTDOWN event, but in abnormal
situations, we should also handle the connection state change and signal
to RRC that the endpoint is dead, which is now implemented.
Remove function pointers that were used in the past to implement the
F1(-U) interface in 4G, i.e., to have different functions to handle
split/monolithic operations. As we don't have F1 in 4G anymore (see
commit 9dc2282249), we don't need the
function pointers anymore.
On that occasion, rename the 5G functions by prepending nr_ to them;
this allows to refactor the interface in 5G further (which is not the
focus of this changeset).
In the DU, read slice information from the DU config file. Handle
multiple slices within the F1 Setup Request structure representation,
and forward it via F1 to CU. The DU slice information is stored in the
setup request structure.
