0029452: Application Framework - Failed to read an Ocaf XML document with 1.#QNAN value.

Method XmlObjMgt::GetReal() is improved to (a) recognize NAN and infinity written by old MSVC runtime (like 1.#QNAN and 1.#INF) and (b) detect situation when there are some trailing non-space symbols after the real value, returning False in such case.

Reading of real-valued attributes (single real, array, list) from OCAF XML format is improved to create valid attribute even if parsing of (some) members fails; warning is generated instead of error in such case.

All library-specific macros for defining export / import properties of symbols on Windows (like Standard_API, __Draw_API, _math_API etc.) are eliminated.
Common macro Standard_EXPORT is used in all places where it is necessary.

New macro OCCT_STATIC_BUILD is defined for disabling Standard_EXPORT, to be used instead of HAVE_NO_DLL, though the latter is still supported as well (for compatibility).

To allow building OCCT in static mode on Windows after these changes:
- Files OSD_WNT_1.hxx and OSD_WNT_BREAK.hxx are removed; useful declarations are moved to OSD_WNT.hxx
- In the class IVtkVTK_ShapeData, static fields ARRNAME_MESH_TYPES and ARRNAME_SUBSHAPE_IDS are converted to static inline functions
- Global array ChoixRef defined in IntImp_ComputeTangence.cxx is converted to static function returning element of the array by index
- Unused class Quantity_Convert is removed (it had static field accessed by inline method)
- Struct Approx_Data defined in the same way in BRepApprox_Approx.hxx and GeomInt_WLApprox.hxx is made private member of these classes to avoid name clash
- Some C++ files producing no object code are removed
- In NCollection_EBTree.hxx and StdLPersistent_Collectio.hxx, definition of template virtual method is moved to class definition to avoid MSVC linker warnings on unused symbols

0029481: Implementation of the Feature Removal algorithm

Implementation of the 3D model De-featuring algorithm intended for the removal of the unwanted parts (or features) from the model consisting of solids. The features can be the holes, protrusions, gaps, chamfers, fillets etc.
The algorithm removes all possible requested features from the shape and builds the new shape as a result. The input model is not modified.

On the API level the algorithm is implemented in the class *BRepAlgoAPI_Defeaturing*. The actual features removal is performed by the low-level algorithm *BOPAlgo_RemoveFeatures*.

Documentation of the new classes.
Implementation of the DRAW commands for working with new algorithm.
Test cases for the new functionality.

Changes in other algorithms used by De-featuring algorithm:
- Provide history support for the solids in *ShapeUpgrade_UnifySameDomain* algorithm;
- Implementation of the mechanism to merge History of any Algorithm with standard history methods such as IsDeleted(), Modified() and Generated() into *BRepTools_History*.

Graphic3d_AspectFillArea3d has been extended by new property ::ShadingModel(),
which is set to Graphic3d_TOSM_DEFAULT by default.
The new API allows assigning Shading Model to specific Primitive Array groups
instead of entire Viewer, which was the only possibility before.

Graphic3d_TypeOfShadingModel has been extended with Graphic3d_TOSM_DEFAULT value
meaining that Shading Model defined as default for the Viewer should be used.
Graphic3d_TOSM_NONE has been renamed to Graphic3d_TOSM_UNLIT.
Documentation of Shading Models has been improved by more details.

V3d_TypeOfShadingModel enumeration has been merged into Graphic3d_TypeOfShadingModel
avoiding duplicated definitions and confusion.
Old values has been left for compatibility with old code and can be marked deprecated in future.

Draw Harness command vaspects has been extended by new argument -setShadingModel
for testing Shading Models assigned to entire objects.

OpenGl_SetOfShaderPrograms now holds an array of Shading Models.
OpenGl_ShaderManager interface has been modified and now requires enumeration as input
in several places where Boolean flags have been used previously
(methods ::BindFaceProgram(), ::BindLineProgram(), ::BindMarkerProgram()).

OpenGl_Workspace now defines default (undefined) OpenGl_AspectFace as Graphic3d_TOSM_UNLIT
to simplify indication of primitive groups with undefined Fill Area aspects,
and so that Graphic3d_TOSM_UNLIT set as default Shading Model will not make artifacts on Lines and Markers.
