file upoad handler: if file is already there, don't upload again 

Notes:
1) We still need to read all the data from socket (copy_socket_to_null());
otherwise the client will block on the send, and never get the success reply.
The previous approach (read-only file) didn't do this.
All we're saving is disk I/O on server.

2) The client reports a result only after it know that
all its output files have successfully been uploaded.
It won't re-upload anything if that's the case.
