0027114: [Regression to 6.7] DistShapeShape does not find a solution edge-face

Browse Source 
Extrema Curve / Surface algorithm changed to perform more accurate search.

test case bug25232_8 - improvement, one additional intersection point is detected now.
test case bug23830 - normal behavior, position of extrema is changed.

test case for original issue added.
