using original config to parse share links

[yiguous]

Because Mr. R has appended new "extra" field to sharing protocol, it's time to use the original config of Xray-core when parsing share links.
This commit contains two modifications.

1. append "Name" field to "OutboundDetourConfig".
2. support marshaling "Address".

Maybe we should make more changes in the future, but it is enough currently for VLESS sharing protocol.

If we just "Marshal" current conf.Config, "address" will be like the below.

"address": {
    "Address": "example.com"
}

or

"address": {
    "Address": [
        127,
        0,
        0,
        1
    ]
}

They are not same with document. I think they will make client developers confused.

and the "name" ?

[yiguous]

"name" is used to store descriptive-text. Currently, there is no such field. If not, we must use other field to store it, like "sendThrough", this field will not be used in most cases when developing client. But I think it is better to append a new field "name".

[Fangliding]

No need to add it, config file can be freely added invalid fields, the core will ignore them

I see. The first change has been reverted.
