0029430: [Regression] Curve evaluation at boundary point.

Browse Source 
Before the fix, BRepAdaptor_CompCurve considered the input wire to be periodic with period LastParameter()-FirstParameter().
Now, method IsPeriodic will always return FALSE because it is impossible to obtain correspondence between the members of BRepAdaptor_CompCurve class and its periodicity status.
New behavior has been documented in upgrade-guide.
