Expose install_fatal_error_handler() through the C API.
I expose the API with some caveats:
- The C++ API involves a traditional void* opaque pointer for the fatal
error callback. The C API doesn’t do this. I don’t think that the void*
opaque pointer makes any sense since this is a global callback - there will
only be one of them. So if you need to pass some data to your callback,
just put it in a global variable.
- The bindings will ignore the gen_crash_diag boolean. I ignore it because
(1) I don’t know what it does, (2) it’s not documented AFAIK, and (3) I
couldn’t imagine any use for it. I made the gut call that it probably
wasn’t important enough to expose through the C API.
