Greenend SFTP server release 2

[Richard Kettlewell]

This is to announce release 2 of my SFTP server.  It is possible to use 
it with the OpenSSH server as a drop-in replacement for the SFTP server 
that it ships with.

It differs from the OpenSSH SFTP server in the following ways:
     * Support for protocol versions up to 6
     * Several SFTP extensions
     * Concurrent handling of pipelined requests

See https://github.com/ewxrjk/sftpserver/blob/master/CHANGES.md for 
change history.
