Did some adjustents to the code-style (in fact, got my IDE set up to keep track of it).
Made a few changes to the list management code, as the old version had a severe logical error in device removal handling.

Noticed a very minor issue with this PR - the code lacks a pthread_join in hotlplug_cleanup. Might cause some weird behaviour in a very narrow case when all callbacks are deleted and then a new one is installed immediately and the background thread didn't have enough time to stop. Going to fix in a moment.

Fixed the cleanup procedure. Doesn't affect how the events themselves work.
