Revert "[glib/ucdn/icu/ft/ot] Make returned funcs inert"
This reverts commit 5daf3bd4494cce6b4fb074533be9e99c4d9e0edd.
If other atexit callbacks try to destruct the objects we destruct
in atexit callbacks, bad things will happen.
I'll come up with some other way to catch premature destruction
of HB-owned objects.

Poison freed objects such that double-free is detected
Previously we were setting refcount of freed objects to the inert value, which
was harmful because it caused further destroy()s of the freed object to NOT
call free() and hence hide the bug. Indeed, after eb0bf3ae6688b7 test-object
was double-free'ing objects and this was never caught on Linux. It only was
caught as crashing on Mac.
Now we poison refcount upon freeing and check that it's valid whenever reading
it. Makes test-object fail now.

Minor refactoring to the atomics implementation
s/atomic_int/atomic_int_impl/ and s/atomic_ptr/atomic_ptr_impl/
to bring it in par with hb_mutex_impl_t, then re-introduce
hb_atomic_int_t as a wrapper around hb_atomic_int_impl_t.
In hb_reference_count_t, make it clear the non-atomic get and set
are intentional due to nature of the cases they are used in
(comparison to -1 and the debug output/tracing).

Add support for atomic int and mutex on Apple systems
So, apparently there's no atomic int 'get' method on Apple. You have to
add(0) to get. And that's not const-friendly. So switch inert-object
checking to a non-atomic get. This, however, is safe, and a negligible
performance boost too.
