Function silc_async_alloc SYNOPSIS
        SilcAsyncOperation silc_async_alloc(SilcAsyncOperationAbort abort_cb,
                                            SilcAsyncOperationPause pause_cb,
                                            void *context);
DESCRIPTION
        Start asynchronous operation, and assign `abort_cb' callback for it,
        which can be used by some upper layer to abort the asynchronous
        operation, by calling the silc_async_abort.  The layer which calls
        this function must also call silc_async_free when the asynchronous
        operation is successfully completed.  If it is aborted by upper layer
        then silc_async_free must not be called, since it is called by the
        silc_async_abort function.

        If the `pause_cb' is provided then the upper layer may also halt and
        then later resume the execution of the operation, by calling the
        silc_async_halt and silc_async_resume respectively.  If `pause_cb' is
        not provided then these functions has no effect for this operation.
EXAMPLE
        SilcAsyncOperation silc_async_call(Callback callback, void *cb_context)
        {
          SilcAsyncOperation op;
          ...

          // Allocate async operation so that caller can control us, like abort
          op = silc_async_alloc(silc_async_call_abort, NULL, ctx);

          // Start async operation in FSM
          silc_fsm_init(&ctx->fsm, ctx, fsm_destructor, ctx, schedule);
          silc_fsm_start(&ctx->fsm, first_state);
          ...

          // Return async operation for upper layer
          return op;
        }
