These are marked `Action' (which of course nobody pays
attention to).

[cite]
G_SIGNAL_ACTION

Action signals are signals that may freely be emitted on
alive objects from user code via g_signal_emit() and
friends, without the need of being embedded into extra code
that performs pre or post emission adjustments on the
object. They can also be thought of as object methods which
can be called generically by third-party code.

I would be less confusing if a plain C function equivalent
existed for all these action signals...

I don't have the feeling the documentation tries to hide
from you that you can emit signals on objects yourself to
invoke the reaction on this signal.
