0029204: BRepOffsetAPI_MakePipeShell produces invalid result and raises exception in Draw

1.The algorithm searching the section in the corner (ChooseSection) is modified to be able to find simple cases with rather big tolerance.

2. The constructor of BRepFill_Section is modified: now it removes locations in the shape of section like it was done in BRepFill_Pipe.

3. Correction of U-edges by Same Parameter has been added to the method BRepFill_Sweep::Build.
