Remove GPL-3.0+ from license identifiers Since we also license under GPL-3.0 WITH Qt-GPL-exception-1.0, this applies only to a hypothetical newer version of GPL, that doesn't exist yet. If such a version emerges, we can still decide to relicense... While at it, replace (deprecated) GPL-3.0 with more explicit GPL-3.0-only Change was done by running find . -type f -exec perl -pi -e "s/LicenseRef-Qt-Commercial OR GPL-3.0\+ OR GPL-3.0 WITH Qt-GPL-exception-1.0/LicenseRef-Qt-Commercial OR GPL-3.0-only WITH Qt-GPL-exception-1.0/g" {} \; Change-Id: I5097e6ce8d10233993ee30d7e25120e2659eb10b Reviewed-by: Eike Ziller <eike.ziller@qt.io>

Tracing: Add Chrome Trace Format Visualizer plugin This new plugin adds a viewer for Chrome Trace Format (CTF) files (aka Trace Event Format). It uses the same UI components as the QML Profiler timeline and the Perf Profiler. The Trace Event Format is generated by different kinds of tracing tools. Usually the files are display with the trace-viewer, built into Chrome (chrome://tracing). This plugin was developed because of the high memory usage of trace-viewer, which makes it difficult to use with trace files bigger than 100 MB. The plugin fully supports all event types used in data generated by LTTng, converted to CTF by https://github.com/KDAB/ctf2ctf. Some of the more advanced event types used for example in Android system traces, though, are not supported. The viewer will silently ignore unsupported event types. Supported Event Types: - Begin, End, Duration and Instant events - Counter events (graphs) - Metadata events (process and thread name) The plugin uses nlohmann/json instead of QJson because of the ~128 MB object size limit by QJson.

CtfVisualizer: Do some cleanup Remove unused headers. Use using namespace and drop unneeded namespace scopes. Replace QVector with QList. Return default constructed objects in default return statements. Avoid empty arg brackets in some lambdas. Use default member initializers.
