[Qemu-devel] [PATCH v4 06/17] trace: break circular dependency in event-internal.h

["Daniel P. Berrange" <berrange@redhat.com>]

Currently event-internal.h includes generated-events.h,
while generated-events.h includes event-internal.h
causing a circular dependency.

event-internal.h requires that the content of
generated-events.h comes first, so that it can see
the typedefs for TraceEventID and TraceEventVCPUID.

Switching the TraceEvent struct to use uint32_t
for the two ID fields, removes the dependency on
the typedef, allowing events-internal.h to be a
self-contained header. This will then let the patch
following this move event-internal.h to the top of
generated-events.h, so we can expose TraceEvent
struct variables in generated-events.h
