[Bug report & fix] Invalid computation of edge length on periodic curve leads to wrong tessellation

Posted by Roman Lygin at June 25. 2011

- Detailed description: SMESH_Algo returns incorrect edge length (1e-08) for an edge lying
         beyond periodic curve range. Afterwards the number of segments is computed as
         ~ 1/lentgh and becomes 1.9M leading to running out of memory or failure to produce
         2D mesh.
- Reproducer: Try to mesh f-percrvedge.brep with 1D Wire Discretization and default
         MaxSize hypothesis.
- Files:
       SMESH_SRC_x.y.z/src/SMESH/SMESH_Algo.cxx

Fixes for 5.1.5 and 6.3.0 are enclosed.
