qt4: remove b_is_node and use childCount() > 0 instead in playlist_model<br>
</blockquote></div><br>This commit is wrong: playlist_item_t->i_children > -1 is not equal to childCount() > 0!<br>The former tells us if the item is of node type or not. But an item can be node and still have i_children == 0, hence childCount() == 0! And vice versa, a PLItem can have childCount() == 0, but not be a node!<br>
<br>The problem is that checking playlist_item_t->i_children demands playlist-locking, but locking inside PLModel::flags() when we need this information results in a deadlock - tested. That was the reason for storing the information as PLItem::b_is_node and updating it when playlist_item_t changes to node.<br>
