Android: Change how detecting call state (introduced in r27746) works, from polling to event based.

* For some reason, the polling methid is much more inefficient than I thought. According to htop it caused up to 15% CPU load on some phones (e.g. Galaxy S).
The event based causes no CPU load.
Rockbox' idle CPU load is now back to 0%, while it was previously dominated by polling the call state.

* Also stop on outgoing calls (no need to explicitely pause for making a call anymore).
* Factor out the detection mechanism to separate files.
