dlclose() a C++ plugin that was built with a faulty library that may have
registered __cxa_atexit callbacks (usually through the libstdc++ that
library was built with).

Upgrading libstdc++ is not always a solution since some code may have been
inlined and we can't get rid of it.

For each item that was appended or deleted, the ("Tracks", NULL) pair
was inserted (duplicated over and over) in the tracklist_properties
dictionary. The dictionary was inserting it in the same position and
it assumed it had hash collisions, triggering an expansion at every
insertion of that pair.

Check if the key is present before inserting in the dict again, at
playlist_item_append, playlist_item_deleted events.
