The orig_cpu parameter in trace_sched_migrate_task() is not necessary,
it can be got by using task_cpu(p) in the probe.

The TRACE_FORMAT will soon be deprecated. This patch converts it to
the TRACE_EVENT macro.
Note, this change should also speed up the tracing.

Now that we can support the dynamic sized string, make the lock tracing
able to use it, making it safe against modules removal and consuming
the right amount of memory needed for each lock name
Changes in v2:
adapt to the __ending_string() updates and the opening_string() removal.
[ Impact: protect lock tracer against module removal ]

Impact: clean up
Create a sub directory in include/trace called events to keep the
trace point headers in their own separate directory. Only headers that
declare trace points should be defined in this directory.
