kgv dde6883382 0027772: Foundation Classes - define Standard_Boolean using C++ type "bool" instead of "unsigned int" 
Code has been updated to remove no-op casts and implicit casts to Standard_Boolean.

Places of inproper use of Standard_Boolean instead of Standard_Integer
have been corrected:
- Bnd_Box, Bnd_Box2d
  Bit flags are now defined as private enum
- HLRAlgo_BiPoint, HLRAlgo_EdgesBlock, HLRBRep_EdgeData, HLRBRep_FaceData
  Bit flags are now defined as enum
- HLRAlgo_EdgeStatus, HLRBRep_BiPnt2D, HLRBRep_BiPoint
  Bit flags are now defined as bool fields
- HLRAlgo_PolyData
  Bit flags are now defined as Standard_Integer
- OSD_DirectoryIterator, OSD_FileIterator
  Boolean flag is now defined as Standard_Boolean
- ShapeAnalysis_Surface::SurfaceNewton()
  now returns Standard_Integer (values 0, 1 or 3)
- ChFi2d_FilletAlgo
  now uses TColStd_SequenceOfBoolean instead of TColStd_SequenceOfInteger
  for storing boolean flags

Method IFSelect_Dispatch::PacketsCount() has been dropped from interface.

ShapeFix_Solid::Status() has been fixed to decode requested status
instead of returning integer value.

TopOpeBRepBuild_Builder1 now defines map storing Standard_Boolean values
instead of Standard_Integer.

Persistence for Standard_Boolean type has been corrected
to keep backward compatibility:
- BinMDataStd, BinTools, FSD_BinaryFile

Broken Draw Harness commands vdisplaymode and verasemode have been removed.

BRepMesh_FastDiscretFace::initDataStructure() - workaround old gcc limitations

BRepMesh_IncrementalMesh::clear() - avoid ambiguity
