["René Scharfe" <l.s.r@web.de>]

Changes since v1:
- add macro BARF_UNLESS_COPYABLE
- use __builtin_types_compatible_p if available

  factor out BARF_UNLESS_COPYABLE
  do full type check in BARF_UNLESS_COPYABLE
  add DUP_ARRAY
  use DUP_ARRAY

         That would be more versatile, as it could be used in declarations as

    +    C23, though.

         So use the safe and compatible variant for now.
