- removed calls to rsfiles->get{Download,Partials}Directory() in RsDiscSpace class, since it would trigger a call to ftController

Browse Source 
- added a lock into ftTransferModule::recvFileData() (Crash reported by Costa due to storing data in a deleted transfer module)
- changed names of functions in ftTransferModules to locked_* when appropriate (helps debugging)
