This is similar to g_signal_connect_data(), but uses a closure which
ensures that the gobject stays alive during the call to c_handler
by temporarily adding a reference count to gobject.
When the gobject is destroyed the signal handler will be automatically
disconnected. Note that this is not currently threadsafe (ie:
emitting a signal while gobject is being destroyed in another thread
is not safe).
