0024129: Eliminate remaining compiler warnings in MSVC++ 2008 32 bit with warning level 4

List of resolved warnings:

c4063: Aspect.cdl; TObj_Application.cxx; PCDM.cdl; OpenGl_Workspace_5.cxx;
c4100: XDEDRAW.cxx; ViewerTest_ViewerCommands.cxx; TopOpeBRep_FacesFiller_1.cxx; TopClass_Classifier3d.gxx; TDataStd_ReferenceArray.cxx; QABugs_19.cxx; IntPatch_ImpImpIntersection_5.gxx; HLRTopoBRep_DSFiller.cxx; HLRBRep_Data.lxx; DPrsStd_AISPresentationCommands.cxx; BRepMesh_Delaun.cxx;
c4127: BOPTools_AlgoTools2D.cxx; MAT_Mat.gxx; GeomFill_SweepSectionGenerator.cxx; BRepMesh_Delaun.cxx;
c4189: IntCurveSurface_Inter.gxx; IGESToBRep_BRepEntity.cxx; BRepMesh_Delaun.cxx; BRepAlgo_Loop.cxx; IntStart_SearchOnBoundaries_1.gxx;
c4190: Plugin_Macro.hxx;
c4389: Visual3d_View.cxx; TopOpeBRep/TopOpeBRep_vpr.cxx; TDataStd_BooleanArray.cxx; IntPatch_ALine.cxx;
c4701: BRepAlgo.cxx;
c4702: MNaming_NamingRetrievalDriver_1.cxx; MNaming_NamingRetrievalDriver_2.cxx; BRepClass3d_SolidExplorer.cxx;
c4706: TestTopOpe_BOOP.cxx;

Additional fixes:
- old-style declarations of C functions in IGES and STEP parsers
- clean-up of debug code, fixes for building in Debug mode
- in BRepFill_TrimShellCorner.cxx, lines 878-9, wrong use of assignment instead of comparison fixed
- fix for Plugin_Macro reverted; warning 4190 disabled instead
- in IntPatch_ALine.cxx, line 520, wrong comparison of boolean with index fixed
- in InterfaceGraphic_Visual3d.hxx, field IsCustomMatrix made boolean
- in TopOpeBRepBuild_ShapeSet, obsolete (unused) methods removed
