Boolean Operations:
1. Face/Face intersection post treatment - Unify vertices put on the section curves, which were rejected as existing ones, with the vertices of edges by which these section curves have been rejected.

2. Extend Warnings Reporting system of Boolean operations with the new warnings:
- BOPAlgo_AlertIntersectionOfPairOfShapesFailed - to be added when the intersection of pair of sub-shapes of the arguments has failed;
- BOPAlgo_AlertBuildingPCurveFailed - to be added when the building of the 2D curve of the edge on face has failed;
- BOPAlgo_AlertAcquiredSelfIntersection - to be added when the positioning and tolerances of the arguments leads to creation of self-interfered shapes.

These new warnings allow completing the operation even if intersection of some of the sub-shapes or building of some of the PCurves has failed. Moreover, they allow getting the pairs of sub-shapes on which the intersection/projection has failed, providing the user ability to analyze the intersection results.

Note that if some of these warnings appear, the result of the operation should be carefully analyzed for validity.

3. Print messages for the Warnings/Errors met during checking of the shape on self-intersection ("bopcheck" command).

0. Basic tools for defining classes representing alerts (errors, warnings etc.) and collecting them during execution of algorithms are added in Message package.

1. Refactoring of the Error/Warning reporting system of the algorithms in Boolean Component.
   To dump the description of the Error/Warning status of the algorithm the DumpErrors/DumpWarnings method should be called.
   Also, the methods GerErrorMsg(int Error) and GetWarningMsg(int Warning) have been implemented to get the description for the given Error/Warning.
   All Error/Warning statuses are now listed in the enumeration ErrorStatusEnum/WarningStatusEnum of the algorithm.
   It is also possible to get the shapes for which the warning has been set by using the method GetWarningShapes().

2. The new class BOPAlgo_Options has been created to unify the options of the BOPAlgo_* and BRepAlgoAPI* algorithms.

3. The new checks across the algorithms have been added to detect and report errors and warnings.

4. Test cases
  boolean bopcut_complex B9 E1 E5 E8
  boolean bopfuse_complex B4 B5 C9 D1 D4 D5 D6 D7
have been rewritten to use Cells Builder algorithm instead of Boolean Operations algorithm, because latter always returns error "Unsupported Boolean operation" for these cases.

5. New chapter has been added in the user guide for Boolean Operations - Error / Warning reporting system.

6. Added comment to NCollection_List::Remove(Iterator&)

0028284: Avoid classification of sub-shapes of arguments of BOPs relatively solids during Intersection phase

1. The methods PerformVZ, PerformEZ, PerformFZ and PerformZZ have been transferred from BOPAlgo_PaveFiller to BOPAlgo_CheckerSI class
to perform intersection of sub-shapes with solids only in self-intersection mode.

2. The checks for solids built from the same (shared) faces have been added into methods building the result of Boolean operations -
BOPAlgo_BOP::BuildRC() and BOPAlgo_BOP::BuildSolid().

3. Since the NonDestructive mode is now natively supported by the BOPAlgo_PaveFiller the methods providing the support of this mode by CheckerSI
(BOPAlgo_CheckerSI::PrepareCopy() and BOPAlgo_CheckerSI::PostTreatCopy()) are not needed and have been removed.

4. The pairs of sub-shapes with interfering bounding boxes are now sorted before real intersection to guarantee the constant order of
intersection of sub-shapes and produce more stable result. The class BOPDS_PassKey has been replaced with simpler class BOPDS_Pair.

5. The class BOPDS_SubIterator has been refactored.

6. Test cases for the issue.

7. Adjustment of the test case boolean volumemaker D2.

The Gluing operation is an additional option for the algorithms in the Boolean Component
such as General Fuse, Boolean operations, Section operation, Maker Volume and Cells Builder algorithms.

The Gluing options have been designed to speed up the computation of the interference among arguments of the operations on special cases,
in which the arguments may be overlapping but do not have real intersections between their sub-shapes.

This option cannot be used on the shapes having real intersections, like intersection vertex between edges,
or intersection vertex between edge and a face or intersection line between faces.

The Gluing option is an enumeration implemented in BOPAlgo_GlueEnum.hxx. There are following items in the enum:
* BOPAlgo_GlueOff - default value for the algorithms, Gluing is switched off;
* BOPAlgo_GlueShift - Glue option for shapes with partial coincidence;
* BOPAlgo_GlueFull - Glue option for shapes with full coincidence.

For setting the Gluing options for the algorithm it is just necessary to call the SetGlue(BOPAlgo_GlueEnum) method with appropriate Glue value.

For using this option in DRAW the command bglue has been implemented:
* 0 - default value, Gluing is off;
* 1 - for partial coincidence;
* 2 - for full coincidence

Elimination of the warnings.

When fuzzy option is in force prevent increasing tolerance of input shapes. Instead pass increased by fuzzy value the tolerances of sub-shapes everywhere where it is needed by intersection algorithms.

The following changes in API have been made:

- The methods SetFuzzyValue and FuzzyValue have been moved from the classes BOPAlgo_ArgumentAnalyzer, BOPAlgo_Builder, and BOPAlgo_PaveFiller to the base class BOPAlgo_Algo.
- The public method BOPDS_DS::VerticesOnIn has been renamed to SubShapesOnIn, and the new output parameter theCommonPB has been added.
- In BOPTools_AlgoTools, a new argument "theFuzzyValue" has been added in the methods ComputeVV and AreFacesSameDomain.
- In IntTools_Context, a new argument "theFuzzyValue" has been added in the methods ComputeVE and ComputeVF.
- The methods SetFuzzyValue and FuzzyValue have been added in the classes IntTools_EdgeEdge, IntTools_FaceFace.
- In the class IntTools_EdgeFace, the methods SetTolE, SetTolF, TolE, TolF have been removed, and the methods SetFuzzyValue, FuzzyValue have been added.
- The new argument "theTol" has been added in the method IntTools_WLineTool::DecompositionOfWLine.

Some improvements in algorithms have been made during fighting with regressions:

- Correct initialization of pave blocks for degenerated edges.
- In BOPAlgo_PaveFiller::MakeBlocks(), filter out paves on intersection curve that were put on the curve accidentally due to wide range of E-F intersection vertex.
- In the method IntTools_Tools::ComputeTolerance the margin added to the computed tolerance has been increased up to 0.001%.
- The method BOPAlgo_PaveFiller::PutPaveOnCurve has been corrected in order to use the original vertex tolerance instead of the value increased during putting it on other curves.
- The new method BOPDS_PaveBlock::RemoveExtPave has been added.
- The vertex tolerance computation in BOPTools_AlgoTools::CorrectCurveOnSurface has been improved, taking into account intersection segments between p-curves (to avoid regression on "bugs modalg_6 bug22794").
- Improve IsExistingPaveBlock to make more stable catching of coincidence of common block with section curve (against regression "bugs modalg_4 bug697_2" on Linux).

Test case for the bug has been added.

The following test cases have been updated as improvements:
boolean gdml_private ZH2 ZI7 ZJ7
boolean volumemaker C4

The test case bugs/modalg_4/pro19653 has been corrected to make it stable. See comment inside the script for details.

The test case bugs/modalg_6/bug25880 has been corrected to suppress wrong bfuse commands.

The test bugs/modalg_6/bug26954_3 has been corrected to compare the result with more precise reference value.

The "faulty" TODO in boolean/volumemaker/A8 has been made actual for Linux as well.

//Eliminate compilation error on Linux.

0026796: The result of General Fuse operation is self-intersecting shape

The fix forces creation of new sub-shapes (vertex, edge) when the tolerance of some sub-shape of an argument is to be increased.

This new behavior is turned off by default. It can be turned on using two ways:
1) Setting 'locking' flag of the arguments.
2) Calling the method SetNonDestructive(Standard_True) of the API classes.

Various bug fixes in the algorithm:
- Compute correct tolerance values for intersections of type Line/Line, Line/Plane, Plane/Plane.
- In case of Line/Plane intersection check if line's vertices lie on the plane.
- Do not allow decreasing of the tolerance value of the Line/Line intersection vertex.
- In IntTools_EdgeEdge, call the method FindParameters with proper 3D tolerance of the curve.
- Force making copy of a degenerated edge if its vertex is touched but no 2D intersection with other curves is found.
- Remove pave blocks both ends of which became referring to the same vertex after vertices substitution.
- Avoid exception in IntTools_Context::IsVertexOnLine if Extrema is not done.
- Reduce tolerance of vertex/edge using actual distances to interfered shapes if it was increased due to line/line, line/plane, or plane/plane small intersection angle.
- Update tolerance of edges to reach all representations in a common block.
- In V-E intersections, check if a vertex hits beyond shrunk range, in such case create V-V interference.
- Do not put a section edge to the result if it becomes to be a micro edge after updating its vertex.
- Correctly make vertices same-domain during the work of MakeBlocks.
- Decrease shrunk range at least on a Precision::Confusion() in addition to vertex tolerance.
- Add Confusion to bounding boxes of new shapes in DS
- Add tolerance Precision::Confusion() to compare distances of touching cases to fix regressions.

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.
