Although quite large, this is a straightforward change to separate
card/token related data from card application related data. Before
this change there was a one-to-one relation between card and

This is better in case we need to debug stuff. There is a real change
however: We now lock and unlock the app before changing the reference

What we want to do here is to serialize the call of

and then another call of select_application entered.
We can have a dedicated lock for call of select_application,
but it is easier to re-use APP_LIST_LOCK.

We can use the interrupt transfer to be notified about card status

done after registration of APP.

issuing PC_to_RDR_IccPowerOn), a reader might notifies about no card
availability (because of not yet powered on), even though the card is
ready to be powered on.
