  tests: move apply_helpers functions into own compilation unit
  
  Currently, the "apply_helper" functions used for testing the apply logic are all
  statically defined in the "apply_helpers.h" header file. This may lead to
  warnings from the compiler in case where this header file is included, but not
  all functions it brings along are used in the compilation unit where it has been
  included into.
  
  Fix these potential warnings by moving the implementation into its own
  compilation unit "apply_helpers.c".
