[Qemu-devel] [PATCH v4 0/2] trace: Trace control commands

[Lluís Vilanova]

Adds QAPI/QMP commands to control tracing events, and reimplements some of the
related HMP commands on top.

NOTE: The "trace-event-set-state" command uses a bool 'enable' argument instead
      of an enum 'state'. I'm still not sure if an enum is better than the two
      separate booleans.
