Fix port "0" listen

[Fangliding]

close #6636

附带一些其他panic 和 close #6600

[bytecategory]

我觉得不要急着合并, bye-panic这个分支代表了还有不少Build成功但"运行时具体状态"和下游假设不一致的问题.
例如
root@ubuntu:/fuzz# cat domain-udp-00114514.json
{
"inbounds": [
{
"listen": "",
"port": 11451,
"protocol": "dokodemo-door",
"settings": {
"udp": true
}
}

修复方法: 检查 serverConfig.Address 是否为nil (现在以 1318802 为准)
还有另外一个注释"just panic",(downloadSettings 空目的地导致SplitHTTP nil dereference),我不清楚这么做是不是好的办法. #5997

因为你加了一个vnext[0] 引入了一个新的panic,本来应该failed to build outbound config with tag > infra/conf: failed to build outbound handler for protocol vless > infra/conf: VLESS settings: "vnext" should have one and only one member. Multiple endpoints in "vnext" should use multiple VLESS outbounds and routing balancer instead
这样的.
