Sets task's result to result and completes the task. If result
is not NULL, then result_destroy will be used to free result if
the caller does not take ownership of it with
g_task_propagate_pointer().
"Completes the task" means that for an ordinary asynchronous task
it will either invoke the task's callback, or else queue that
callback to be invoked in the proper GMainContext, or in the next
iteration of the current GMainContext. For a task run via
g_task_run_in_thread() or g_task_run_in_thread_sync(), calling this
method will save result to be returned to the caller later, but
the task will not actually be completed until the GTaskThreadFunc
exits.
Note that since the task may be completed before returning from
g_task_return_pointer(), you cannot assume that result is still
valid after calling this, unless you are still holding another
reference on it.
