 Patch the bug explained below :


 It appears using the username authentication with SOCKS 5.

 After the client and the server have chosen the username authentication,
 the client has to send the following packet :

 Client request (RFC 1929) :

             +----+------+----------+------+----------+
             |VER | ULEN |  UNAME   | PLEN |  PASSWD  |
             +----+------+----------+------+----------+
             | 1  |  1   | 1 to 255 |  1   | 1 to 255 |
             +----+------+----------+------+----------+

 Here the first byte must be 0x1, it specifies the version of the
 authentication mechanisme, not the SOCKS version (0x5) like in all
 others packets.

 However in the socks-protocol.pac the type SOCKS_Version never parses
 data if the first byte is 0x1, and it goes to an error.
