Git commit f856a9a63910a7e9f2fbcbcd63f85100599805ae by Anton Anikin. Committed on 15/09/2018 at 00:26. Pushed by antonanikin into branch 'master'. Fix segfaults in OutputWidget Summary: This patch fixes regressions provided by D14931. Steps to reproduce (my system is neon/bionic with Qt 5.11.1 and KDevelop/master): 1) Start KDevelop and load some project 2) Start project build 3) Close KDevelop 4) Segfault happens Main problems: 1) Incorrect signal processing. `OutputWidget::updateFilter()` slot is called from parent's destructor when `m_tabwidget`/`m_stackwidget` is deleted so we have destroyed `m_views` hash and segfault as a result. 2) Incorrect `QSharedPointer` usage. All handled objects have `QWidget` as a parent so we have double-free problem and and segfault as a result. Test Plan: Tested on different output widgets (`KDevelop::IOutputView::OneView/HistoryView/MultipleView`) with no segfaults. All our `QTreeView`/`QSortFilterProxyModel` objects are deleted (no memory leaks).
