0026229: Add the possibility in OCAF to open/save a document from/to a stream object

Browse Source 
TDocStd_Application class extended to open/save a document of XmlOcaf and BinOcaf format
from/to standard SEEKABLE stream object which should support SEEK functionality.

Open and SaveAs DRAW commands got new additional argument "-stream" to turn on using of stream functionality.

The main changes for BinOcaf format applied in:
FSD_BinaryFile class (static method using standard stream added)
BinLDrivers_DocumentRetrievalDriver and BinLDrivers_DocumentStorageDriver classes use standard stream object as an argument

The main changes for XmlOcaf format applied in:
LDOMParser and LDOM_XmlWriter classes  use standard stream object as an argument

Unused class FSD_Archive and its siblings removed from MFC samples.
