gmem.h: Use __typeof__() in the g_clear_pointer() macro

Type punning is used on the existing implementation, which hides errors
such as:

  GSList *list = NULL;
  g_clear_pointer (&list, g_error_free);

Let's use __typeof__ to cast the passed-in pointer before it's passed to
the free function so it trips -Wincompatible-pointer-types if it's wrong.

Fixes #1425
