Identify new Xunlei versions by peerid and "v" in extension handshake

[conquerist]

Recent Xunlei versions use Azureus style peer IDs with prefix -SD0100-. In the extension handshake message, the "v" entry is set to the version number, e.g. 7.9.20.4754 or 7.9.16.4670. Even though BEP0010 states that the "v" entry should contain "Client name and version (as a utf-8 string)", Xunlei does not include its name in the "v" field.

 

As a result, uTorrent only shows the version number for Xunlei clients, without a "Xunlei" prefix.

 

My feature request is to correctly identify Xunlei clients.
