0023675: P-curves of a face are out of the domain of the face.

Analyzing of 2D-curves' boundaries.
Tolerance range computing was changed.

1. Function Validate(...) returns BRepCheck_Status.
2. For faces, whose pcurves is out of domain, status BRepCheck_OutOfSurfaceBoundary is returned.
3. For edges, which is out of face's boundary, status BRepCheck_PCurveIsOutOfDomainFace is returned.
4. Print warning, if status is not defined.
5. BRepCheck_Face::SetStatus(...) and BRepCheck_Wire::SetStatus(...) functions added.
6. ShapeFix::RefineFace(...) function and it draw-commands (ffixpcu and sfixpcu) are added. Command "ffixpcu" fixes a face with BRepCheck_OutOfSurfaceBoundary status. Command "sfixpcu" fixes a shape, which contains a face with BRepCheck_OutOfSurfaceBoundary status.
7. Trimming algorithm for surfaces changed (ForceTrim method is added).
8. Small correction of output of "checkshape" command result.
9. MinMax() and RealMod() functions are added.
10. Fixing of some shapes from test base.
