-Use better file name generation algorithm for the STOU command.

+Use a better file name generation algorithm for the STOU command. The default

+original algorithm simply adds an increasing number suffix to the file name,

+which is prone to race conditions if multiple uploaders use the STOU command

+with the same file name simultaneously, which can result in failure of the

+command. The new algorithm adds a unique random six character suffix to

+the file name, which works much better in face of concurrent uploads.
