removing the files that are now in rpc_pipes

removing the files that are now in rpc_pipes

For future reference, if you want to move files about then don't do it
this way. The history info is lost.

Instead contact me first and tell me what you want moved and why. Then
I'll decide if we can do it while retaining the history info.
