0423218095 0030895: Coding Rules - specify std namespace explicitly for std::cout and streams
"endl" manipulator for Message_Messenger is renamed to "Message_EndLine".

The following entities from std namespace are now used
with std:: explicitly specified (from Standard_Stream.hxx):
std::istream,std::ostream,std::ofstream,std::ifstream,std::fstream,
std::filebuf,std::streambuf,std::streampos,std::ios,std::cout,std::cerr,
std::cin,std::endl,std::ends,std::flush,std::setw,std::setprecision,
std::hex,std::dec.

7bd071edb1 0026106: BRepMesh - revision of data model
Removed tight connections between data structures, auxiliary tools and algorithms in order to create extensible solution, easy for maintenance and improvements;
Code is separated on several functional units responsible for specific operation for the sake of simplification of debugging and readability;
Introduced new data structures enabling possibility to manipulate discrete model of particular entity (edge, wire, face) in order to perform computations locally instead of processing an entire model.

The workflow of updated component can be divided on six parts:
* Creation of model data structure: source TopoDS_Shape passed to algorithm is analyzed and exploded on faces and edges. For each topological entity corresponding reflection is created in data model. Note that underlying algorithms use data model as input and access it via common interface which allows user to create custom data model with necessary dependencies between particular entities;
* Discretize edges 3D & 2D curves: 3D curve as well as associated set of 2D curves of each model edge is discretized in order to create coherent skeleton used as a base in faces meshing process. In case if some edge of source shape already contains polygonal data which suites specified parameters, it is extracted from shape and stored to the model as is. Each edge is processed separately, adjacency is not taken into account;
* Heal discrete model: source TopoDS_Shape can contain problems, such as open-wire or self-intersections, introduced during design, exchange or modification of model. In addition, some problems like self-intersections can be introduced by roughly discretized edges. This stage is responsible for analysis of discrete model in order to detect and repair faced problems or refuse model’s part for further processing in case if problem cannot be solved;
* Preprocess discrete model: defines actions specific for implemented approach to be performed before meshing of faces. By default, iterates over model faces and checks consistency of existing triangulations. Cleans topological faces and its adjacent edges from polygonal data in case of inconsistency or marks face of discrete model as not required for computation;
* Discretize faces: represents core part performing mesh generation for particular face based on 2D discrete data related to processing face. Caches polygonal data associated with face’s edges in data model for further processing and stores generated mesh to TopoDS_Face;
* Postprocess discrete model: defines actions specific for implemented approach to be performed after meshing of faces. By default, stores polygonal data obtained on previous stage to TopoDS_Edge objects of source model.

Component is now spread over IMeshData, IMeshTools, BRepMeshData and BRepMesh units.

<!break>

1. Extend "tricheck" DRAW-command in order to find degenerated triangles.

2. Class BRepMesh_FastDiscret::Parameters has been declared as deprecated.

3. NURBS range splitter: do not split intervals without necessity. Intervals are split only in case if it is impossible to compute normals directly on intervals.

4. Default value of IMeshTools_Parameters::MinSize has been changed. New value is equal to 0.1*Deflection.

5. Correction of test scripts:

1) perf mesh bug27119: requested deflection is increased from 1e-6 to 1e-5 to keep reasonable performance (but still reproducing original issue)
2) bugs mesh bug26692_1, 2: make snapshot of triangulation instead of wireframe (irrelevant)

Correction in upgrade guide.

b508cbc59f 0026338: STL export (especially binary) needs a lot of time if selected export path is not local
Method StlAPI_Writer::Write() is reimplemented to write triangulation directly, without conversion to StlMesh_Mesh.

New DRAW command "tessellate" is added to generate rapidly triangulation of prescribed size (on surface).

Command "tricheck" is protected to deal correctly with triangulation without UV data.

New tests added: perf de bug26338_1 and _2; bugs stlvrml bug26338

c7b59798ca 0024826: Wrapping of parallelisation algorithms
Simple primitives to parallelize loops type "for" and "foreach" were implemented. The primitives encapsulates complete logic for creating and managing parallel context of loops. Moreover the primitives may be a wrapper for some primitives from 3rd-party library - TBB.

To use it is necessary to implement TBB like interface which is based on functors. For example:

Class Functor
{
public:
  void operator() ([proccesing instance]) const
  {
    //...
  }
};

In the body of the operator () should be implemented thread-safe logic of computations that can be performed in parallel context. If parallelized loop iterates on the collections with direct access by index (such as Vector, Array), it is more efficient to use the primitive ParallelFor (because it has no critical section).

All parts of  OCC code which are using tbb were changed on new primitives.

0024826: Wrapping of parallelisation algorithms

Small fix.

91322f44fd 0022898: IGES import fails in german environment
Added DRAW command dlocale to set and query current locale of the C subsystem
Equivalents of C functions working with conversions of strings to/from reals added in Standard_CString, providing locale-independent behavior (using always "C" locale)
In DRAW packages, calls to atof() and atoi() are replaced by direct calls to Draw::Atof() and Draw::Atoi(), respectively, instead of substituting by #define
Use of atof(), strtod(), and *scanf() involving floating point conversions in OCCT code replaced by locale-independent Atof() and Strtod()
Calls to sprintf() involving floating point in OCCT code are replaced by call to locale-independent Sprintf(), except a few places where converted strings are used immediately for display in the 3d viewer
Changes of global locale are eliminated throughout OCCT code
Proposed correction for GNU libC where v*printf_l functions are absent
Added test case (bugs xde bug22898) for data exchange operations with non-standard locale

Mark test case as skipped if locale is unavailable on tested system.
Use fr_FR locale for tests on Mac OS X
