tracing: Implement system consumer backend
This patch add a consumer backend for the client API, making it possible
to record traces from a system tracing daemon. Note that on some systems
only privileged apps will have read access to the system tracing
service. For example on Android you should use the "perfetto"
command line tool to record system-wide traces instead of the client API.
