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".
