This caused an issue on big endian platforms
From the getsockopt man page:
Most socket-level options utilize an int argument for optval. For setsockopt(), the argument should be non‐
zero to enable a boolean option, or zero if the option is to be disabled.
Fix checking of negative with unsigned variables.
Check digestSz for 0 in wc_SSH_KDF() so that no possibility of dividing
by zero.
Change XMEMCPY to XMEMSET in renesas_sce_util.c.
Fix test.c to free prvTmp and pubTmp on read error.
Remove unused variables.
XFREE checks for NULL so don't check before call.
Move variable declarations to reduce scope.
From the man page
If sendto() is used on a connection-mode (SOCK_STREAM, SOCK_SEQPACKET) socket, the arguments dest_addr and
addrlen are ignored (and the error EISCONN may be returned when they are not NULL and 0), and the error
ENOTCONN is returned when the socket was not actually connected.
Introduce ACK and retransmission logic, encapsulated in a Dtls13RtxFsm
object. The retransmission or the sending of an ACK is scheduled by setting the
appropriate flag inside the Dtls13RtxFSM object but the actual writing on the
socket is deferred and done in wolfSSL_Accept/Connect.
* Retransmission
Each sent message is encapsulated in a Dtl13RtxRecord and saved on a list. If we
receive an ACK for at record, we remove it from the list so it will be not
retransmitted further, then we will retransmit the remaining
ones. Retransmission is throttled: beside link congestion, this also avoid too
many sequence numbers bounded with a record.
* ACK
For each received record we save the record sequence number, so we can send an
ACK if needed. We send an ACK either if explicitly needed by the flight or if we
detect a disruption.

Ignore packet if coming from a peer of a different size *or* from a different
peer. Avoid whole memcmp of sockaddr_in[6] struct because is not portable (there
are optional fields in struct sockaddr_in).
The pending check was forcing a `WOLFSSL_CBIO_ERR_WANT_WRITE` return even though the underlying socket was closed and `WOLFSSL_BIO_FLAG_READ|WOLFSSL_BIO_FLAG_RETRY` was not set. The `wolfSSL_BIO_ctrl_pending(ssl->biord) == 0` is old and I can't find a reason to keep checking it. I left it just in the case where there is output data pending.
