Default function signature of trace_unhandled() got changed to include a
field dict, but its documentation, perf-script-python.txt has not been
updated.  Fix it.

The tracepoints used by the workqueue-stats script no longer exist so
trying to run the script results in:

  # perf script record workqueue-stats
  invalid or unsupported event: 'workqueue:workqueue_creation'
  Run 'perf list' for a list of valid events

So remove the script until it can be reworked using the new workqueue
tracepoints.

Neil Brown pointed out that lock_depth somehow escaped the BKL
removal work.  Let's get rid of it now.

Note that the perf scripting utilities still have a bunch of
code for dealing with common_lock_depth in tracepoints; I have
left that in place in case anybody wants to use that code with
older kernels.

Free the perf trace name space and rename the trace to 'script' which is a
better match for the scripting engine.

-f, -c 1, -R are now useless for trace events recording, moreover
-M is useless and event hurts.

Remove them from the documentation examples and from record scripts.

syscall_name() helper, which resolves a syscall arch number to
its name, is not yet available as we first need to implement
event injection for it to work.

Remove it from the documentation or tag its references as
unavailable yet. Once it's implemented, we can just revert
the current patch.
