[CCID3]: Accurately determine idle & application-limited periods

This fixes/updates the handling of idle and application-limited periods in CCID3,
which currently is broken: there is no detection as to how long a sender has been
idle - there is only one flag which is toggled in between function calls.

Being obsolete now, the `idle' flag is removed.
