add_event_ex is added that takes an extra user_data pointer. This pointer is
passed to the callback (add_event and add_event_ex have slightly different
callbacks types). All callbacks also get the event id passed. Events added
with add_event_ex must be removed with remove_event_ex because the user_data
pointer must match in addition to the callback pointer.
On the other add_event is simplified to omit the oneshort parameter which
was almost always false (still there with add_event_ex).
As a side effect the ata_idle_notify callbacks are changed as well, they
do not take a data parameter anymore which was always NULL anyway.
This commit also adds some documentation to events.h

* Remove explicit tracking of elapsed time of previous track.
* Remove function to obtain auto skip flag.
* Most playback events now carry the extra information instead and
pass 'struct track_event *' for data.
* Tweak scrobbler to use PLAYBACK_EVENT_TRACK_FINISH, which makes
it cleaner and removes the struct mp3entry.

The environment is fine to share in general, just not across OS threads, so it's only needed
for functions which are possibly called from multiple OS threads (only 1 currently).

The added complexity wasn't needed for most subsystems, as main() never returns
so local references can't be freed.
