Merge cpp files

* Properly include tbcore.cpp

* Merge *cpp files

* Additional reshuffle and consolidation

* Cosmetic touch

- run: astyle -A3 -s4 -f -xn -xc -xl *.cpp *.h. Mainly this breaks blocks (if,
  do, while, for etc.)

- remove static_cast<>: inconsistently used, and ugly. Prefer C-style cast.
  Eventually, the code will be rewritten so that less casting is needed...

No functional change.
