No need to link with KDELibs4Support
Use Qt5 signal connection syntax
kDebug(), qDebug() -> qCDebug() with logging category
Use 'override' as identified by GCC 9.3.0
No need for KonqPlacesCustomPlacesView
KInputDialog -> QInputDialog
SmallIcon() -> QIcon::fromTheme()
KMenu -> QMenu
Correct icon names for Bookmarks and History
Correct use of QStandardPaths::locateAll() in ModuleManager::availablePlugins()

Ignoring for the moment subdirectories 'trees' (which needs Qt3Support)
and 'web_module' (which depends on KHTML).
