[Bf-committers] BMesh: fix bmDM_copyEdgeArray, bmDM_copyFaceArray

This fixes edge snapping to edges in the same mesh, and *sort of* does the
same for face snapping to faces in the same mesh although due to a TODO
which I'm currently looking into in bvhutils.c, the face snapping is tough
to use because it will also try to snap to selected faces (while those faces
are moving).
