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.

Small fix.

fc9b36d630 0025039: Improvement of code structure of general and supporting tools implemented in BRepMesh
Removed CDL declarations; Data collections are replaced by NCollections; Small code refactoring.
Remove definition of BRepMesh class. Code refactoring of BRepMesh_IncrementalMesh.
Function BRepMesh_Write storing BRepMesh_DataStructureOfDelaun to BRep file is added for debug needs.
Static method BRepMesh_GeomTool::IntLinLin has been added to eliminate code duplications in BRepMesh_Dealun and BRepMesh_CircleTool.
BRepMesh_CircleTool simplified method to find circumcircle.

01a6e62bc2 0024968: Impove BRepMesh_Classifier to cope with intersection of huge number of wires
BRepMesh_Classifier: Two-pass approach for intersection check with possibility to run it in parallel mode.
First pass - bounding boxes of segments are checked for overlapping;
Second pass - intersection point is calculated in case if overlapping is detected.

Make NCollection_UBTree::ChangeLastNode() exported due to compilation error on Linux platform.
Reason: method does not depend on template parameters, so it should be available.

Revert previous change and try to use another trick for Linux

Fix compilation warning on MacOS: remove redundant constant
Fix regressions: do not consider insignificant loops in case of self intersections on the same wire.
More sugar solution for compilation errors on NCollection_EBTree on Linux
