ifv 91a2f58f8f 0026441: Modeling Algorithms - BRepOffset_MakeOffset affects original shape
BRepOffset_MakeOffset.cxx - tolerance control for building planar faces is implemented,
                            updating tolerance for initial entities is avoided

BRepAlgo_Loop.cxx - "total" setting tolerance 0.001 is removing

BRepLib.cxx - checking of "locked" for vertex is removing in static function UpdShTol

QABugs_20.cxx - add new command OCC26441 for checking tolerance differenses between two "identical" shapes

tests/bugs/modalg_7/bug30054 - case now is "BAD", because really result shape is invalid: many faces has not closed wires with huge gaps between ends of edges. Result was "OK" only because tolerances of vertices were increased by algorithm to cover all gaps.

tests/bugs/modalg_8/bug26441 - new test case added

Other test: B3, C8, A7, C8: they were "BAD" and now are "BAD", only some problems are changed.
