[Qemu-devel] [PULL 13/13] trace: Add a proper API to manage auto-generated events from the 'tcg' property

[Stefan Hajnoczi <stefanha@redhat.com>]

From: Lluís Vilanova <vilanova@ac.upc.edu>

Formalizes the existence of the 'event_trans' and 'event_exec' event
attributes, which until now were monkey-patched only when necessary.
