Pointed by strict compiler warnings, but some of the reports were
actually a real bugs:
- Access uninitialized memory of td_mirror_iter.
Assuming that iterator is to point to the first element of the
data array.
- Lattice's recalc data was never called.
There is also a fix for redundant declaration of recalcData() and
missing declaration of recalcData_lattice().
