0029014: Managing Binary Format Version Is Not Possible for Own TDF_Attributes

Browse Source 
CDM_Application has been extended to provide application name and version.

Application name and version is stored by BinLDrivers_DocumentStorageDriver.

BinLDrivers_DocumentStorageDriver propagates application name and version
by passing it to BinMDataStd.

Made BinObjMgt_RRelocationTable store a handle to the header data of the file
begin read in to make it accessible by binary attribute drivers.

Undone storing application name and version as static fields in BinMDataStd
which is bad style and not thread-safe.

Moved method implementations to .cxx files.

Clearing a BinObjMgt_RRelocationTable now nullifies the reference to the
file header data and BinLDrivers_DocumentRetrievalDriver therefore sets
the reference after the relocation table has been cleared before reading
in the document subtree.
