azn 96f3baccc5 0025619: CAST analysis: Avoid classes with a non-empty destructor and not implementing both an assignment operator and a copy constructor
- Fix compilation errors.
- Branch has been rebased on new master.

0025619: CAST analysis: Avoid classes with a non-empty destructor and not implementing both an assignment operator and a copy constructor

The problem has been removed from following classes:
- tsee_entity
- Select3D_PointData
- Standard_MMgrFactory
- ProjLib_OnSurface
- BinomAllocator
- OSD_PerfMeter
- StorageInfo
- OpenGl_UnpackAlignmentSentry
- IntPatch_InfoPD
- TableauRejection
- Draw_View
- BOPTest_Session
- BOPCol_MemBlock
- BSB_T3Bits
- NCollection_Handle::Ptr
- Buffer (from Standard_Boolean Message_MsgFile::LoadFile (const Standard_CString))
