* nix/libutil/gcrypt-hash.hh (struct guix_hash_context): Add a
  constructor and a copy constructor; move out of 'extern "C"'.
* nix/libutil/gcrypt-hash.cc (guix_hash_final): Clear 'md_handle' upon
  exit.
* nix/sync-with-upstream (top_srcdir): Change hash.{cc,hh} to read
  'struct Ctx' instead of 'union Ctx'.
