Message:

Main,VBoxService,GstCtrlSvc: Added functions for exchanging feature masks between guest and host so new features can more easily be added without resorting to version comparsion magic. Added alternative read and write completion notifications that includes the new file offset. Made sure RTFileReadAt and RTFileWriteAt are followed by a RTFileSeek call so we'll end up with the same file position regardless of guest OS. [fixes] bugref:9320
