| | | | | | | | | | | A coming change to support streaming requires networking so having it in corelib is dubious.

* CTF: Fix plugin cleanupAntti Määttä2023-02-101-0/+6
| | | | | | | | | | Handle cleanup of the CTF plugin correctly. The cleanup causes recursive trace event so the plugin needs to handle this.

* Add CTF tracing backendAntti Määttä2023-01-131-0/+303
Implement platform independent tracing backend in Common trace format. This allows tracing in platforms without own/existing backend and analysing all platforms with the same tooling. The backend is the basis for further work in application level profiling area. The backend is implemented as a plugin that is loaded immediately when the application starts in order to process all trace events. The backend avoids using Qt classes so that it doesn't generate trace events itself. Adds plumbing to configure the new backend. Modifies the tracegen and tracepointgen tools to support the new backend.
