Use typeof everywhere instead of compiler specific spellings

Browse source 
We define typeof ourselves as __typeof__ if it does not exist.  So
let's actually use that for consistency.  The meson/autoconf checks
for __builtin_types_compatible_p still use __typeof__ though, because
there we have not redefined it.
