    trace: remove the TraceEventID and TraceEventVCPUID enums · ef4c9fc8
    Daniel P. Berrange authored
    The TraceEventID and TraceEventVCPUID enums constants are
    no longer actually used for anything critical.
    The TRACE_EVENT_COUNT limit is used to determine the size
    of the TraceEvents array, and can be removed if we just
    NULL terminate the array instead.
    The TRACE_VCPU_EVENT_COUNT limit is used as a magic value
    for marking non-vCPU events, and also for declaring the
    size of the trace dstate mask in the CPUState struct.
    The former usage can be replaced by a dedicated constant
    TRACE_EVENT_VCPU_NONE, defined as (uint32_t)-1. For the
    latter usage, we can simply define a constant for the
    number of VCPUs, avoiding the need for the full enum.
    The only other usages of the enum values can be replaced
    by accesing the id/vcpu_id fields via the named TraceEvent
