The module cannot be built without HTTP support, so each and every file had an `#ifndef QT_NO_HTTP` check. However, commit d49f744968a237b751f0e520f8a9fff59dc283f5 already disabled the module build at the toplevel CMakeLists.txt file if the relevant feature is not found. As a result, we can drop the checks from the private headers and the .cpp files and also remove the QtNetwork/qtnetwork-config.h includes that were added in order to provide access to QT_NO_HTTP definition. This patch still keeps the QT_NO_HTTP check on public headers, because it allows the user code like: #include <QOAuth1> // unconditionally ... #ifndef QT_NO_HTTP QOAuth1 oauth; // use oauth #endif // QT_NO_HTTP Pick-to: 6.9 6.8 6.5 Change-Id: I517aa1da90ed53a5fc013d28530aa1d41a946a79 Reviewed-by: Juha Vuolle <juha.vuolle@qt.io> Reviewed-by: Marc Mutz <marc.mutz@qt.io> Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>
