Introduce an indirection layer for pointers

As the Go runtime can move stacks at any point and the C code runs
concurrently with the rest of the system, we cannot assume that the
payloads we give to the C code will stay valid for any particular
duration.

We must therefore give the C code handles which we can then look up in
our own list when the callbacks get called.
