    tracing: Set up infrastructure to allow tracers for instances · 607e2ea1

    Currently the tracers (function, function_graph, irqsoff, etc) can only
    be used by the top level tracing directory (not for instances).
    
    This sets up the infrastructure to allow instances to be able to
    run a separate tracer apart from the what the top level tracing is
    doing.
    
    As tracers need to adapt for being used by instances, the tracers
    must flag if they can be used by instances or not. Currently only the
    'nop' tracer can be used by all instances.
