Big cleanup for appendsolution()

With this PR the appendsolution routine is extracted from the h48
solver and the new coordinate solver and made generic. This has
many advantages:
- less repetition (even if the two versions are different enough that
  *for now* it was not a big deal)
- smaller h48/solve.h file, which is already a big beast
- easier to test the appendsolution() routine separately
