bmesh-decimator update

- update face normals when triangulating.
- avoid divide by zero when interpolating customdata on a zero length edge.
- replace zero float comparisons with fabsf() < FLT_EPSILON to avoid numeric error.

also renamed BLI_heap_empty() --> BLI_heap_is_empty() so its obviously readonly function.
