Hi.
Is it possible, that add_event/remove_event API will be called in scope of callback (line 232). If so, crash will occur because 'event_list' will be modified during the iteration. To avoid this copy on write semantics should be implemented.

This PR tries to fix the issue #113.
A mutex and guard_locks are added in BluetoothManager to synchronize the access to the event_list.
I'm not a C++ expert, so please check it before merging!
