[Libguestfs] [libnbd PATCH 01/23] generator: split LIBNBD_ATTRIBUTE_NONNULL replacement text

[Laszlo Ersek]

The LIBNBD_ATTRIBUTE_NONNULL replacement text is just a bit too long;
split the macro definition similarly to LIBNBD_ATTRIBUTE_ALLOC_DEALLOC.

It changes "include/libnbd.h" like this:

>  #ifndef LIBNBD_ATTRIBUTE_NONNULL
>  #if defined (__GNUC__) && LIBNBD_GCC_VERSION >= 120000 /* gcc >= 12.0 */
> -#define LIBNBD_ATTRIBUTE_NONNULL(...) __attribute__ ((__nonnull__ (__VA_ARGS__)))
> +#define LIBNBD_ATTRIBUTE_NONNULL(...) \
> +  __attribute__ ((__nonnull__ (__VA_ARGS__)))
>  #else
>  #define LIBNBD_ATTRIBUTE_NONNULL(...)
>  #endif
