0028196: Modeling Data - Algorithm 'Extrema_GenLocateExtPS' failed to find the extremum in a case

Browse Source 
Extrema_GenLocateExtPS.cxx, Extrema_GenLocateExtPS.hxx:

Adjusting tolerances according to surface sizes is added.
Additional methods for searching solution are added for cases if basic method fails.

Extrema_FuncPSDist.cxx - small bug fixing.

BRepFill_TrimShellCorner.cxx - fixing regression

ChFi3d_Builder_CnCrn.cxx setting parameters for Plate algorithm to improve stability of solution

ProjLib_ComputeApproxOnPolarSurface.cxx - code optimization

Some test cases are modified according to current state of Extrema algorithm
