[sftp-server.c sftp.1 sftp-client.h sftp.c PROTOCOL sftp-client.c]
add a protocol extension to support a hard link operation. It is
available through the "ln" command in the client. The old "ln"
behaviour of creating a symlink is available using its "-s" option
or through the preexisting "symlink" command; based on a patch from
