0027954: Create topology-preserving offset computation algorithm

Browse Source 
New topology-preserving offset algorithm has been added. It allows to construct offset shape of build solid.
test cases have been added.
Documentation has been updated to be up to date.

Minor corrections.
Grid is renamed for simplification purposes.
Old constructors are restored with Standard_DEPRECATED macros.

* The last optional argument *RemoveInvalidFaces* has been removed from the constructor of class *BRepOffset_MakeOffset* and method *Initialize*.
* The public method *BOPDS_DS::VerticesOnIn* has been renamed into *SubShapesOnIn* and the new output parameter *theCommonPB* has been added.

Class *BRepOffsetAPI_MakeOffsetShape*:
* *BRepOffsetAPI_MakeOffsetShape::BRepOffsetAPI_MakeOffsetShape()* - constructor with parameters has been deleted.
* *BRepOffsetAPI_MakeOffsetShape::PerformByJoin()* - method has been added. This method is old algorithm behaviour.
The code below shows new calling procedure:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
BRepOffsetAPI_MakeOffsetShape OffsetMaker;
OffsetMaker.PerformByJoin(Shape, OffsetValue, Tolerance);
NewShape = OffsetMaker.Shape();
