commit 5b9c420 introduced some undesirable behaviour with packet send functions returning error when they shouldn't. We now only return an error if the packet fails to be added to the send queue or cannot be wrapped/encrypted. We no longer error if we fail to send the packet over the wire, because toxcore will keep trying to re-send the packet until the connection times out. Additionally, we now make sure that our packet broadcast functions aren't returning an error when failing to send packets to peers that we have not successfully handshaked with yet, since this is expected behaviour.

We allow non-null data pointers to be passed to functions alongside 0-length data. For example when creating a data buffer that has room for the entire packet, including ignored header data.
This error broke a rare but legitimate case where we miss packets during a handshake attempt and need to store empty handshake packets in the packet array.
