Resolving the sample->id to an evsel since the most advanced tools,
report and annotate, and the others will too when they evolve to
properly support multi-event perf.data files.
Good also because it does an extra validation, checking that the ID is
valid when present. When that is not the case, the overhead is just a
branch + function call (perf_evlist__id2evsel).

GCC 4.6.0 in Fedora rawhide turned up some compile errors in tools/perf
due to the -Werror=unused-but-set-variable flag.
I've gone through and annotated some of the assignments that had side
effects (ie: return value from a function) with the __used annotation,
and in some cases, just removed unused code.
In a few cases, we were assigning something useful, but not using it in
later parts of the function.

[ committer note: Fixed up the annotation fixes, as that code moved recently ]

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

trace_unhandled() callback does not allow to access event fields, this patch
resolves the problem.
It can also been used as a more pythonic and flexible way for script writters
to demux event types
This will for example greatly simplify pytimechart event demux.

Only print the script start/stop messages in verbose mode - users
normally don't care and it just clutters up the output.

This is a fix to the signed/unsigned field handling in the
Python scripting engine, based on a patch from Roel Kluin.
Basically, Python wants to use a PyInt (which is internally a
long) if it can i.e. if the value will fit into that type. If
not, it stores it into a PyLong, which isn't actually a long,
but an arbitrary-precision integer variable.
The code below is similar to to what Python does internally, and
it seems to work as expected on the x86 and x86_64 sytems I
tested it on.

If we know the size of a tuple in advance, there's no need to resize
it - start out with the known size in the first place.

Create a scripting-engines directory to contain scripting engine
implementation code, in anticipation of the addition of new scripting
support. Also removes trace-event-perl.h.
