Summary0022629: Typo in Geom2d_BSplineCurve::LocateU()
DescriptionRLN contribution.
Summary: Typo in Geom2d_BSplineCurve::LocateU() - which uses a value not
adjusted to period for periodic B-Splines.

Detailed description: The bug shows up on periodic B-Splines when due to
rounding issues the U parameter is slightly below the min knot (e.g. 0 vs
1e-18). NewU bumps up to 0 + period but due to wrong check, another if branch is
chosen (one which uses BSplCLib::Hunt()) and respectively an exception later is
thrown due to access beyond the max knot item.
Similar code in Geom_BSplineCurve and Geom_BSplineSurface is correct.
Another minor improvements:
- computation of Abs(ParametricTolerance) only once.
- removed Abs(ParametricTolerance) in the 3rd and 4th branch as they are
irrelevant after 1st and 2nd.
