Introduce macros CCTK_DECLARE and CCTK_DECLARE_INIT which declare or
declare and initialise local variables. They also add the necessary
magic to prevent compiler warnings about unused variables.
If the compiler supports __attribute__((unused)), then use this.
Otherwise, use the existing fallback of taking the variable's
address. In Fortran, use the variable's kind as fallback.
Use these macros in autogenerated code and in "cctk.h".
