parameter for "process_event()"
Both perl and python script start processing events other than trace
points, and it's useful to pass the resolved symbol and the dso info to
the event handler in script for better analysis and statistics.
Struct thread is already a member of struct addr_location, using
addr_location will keep the thread info, while providing additional
symbol and dso info if exist, so that the script itself doesn't need to
bother to do the symbol resolving and dso searching work.

We can get all that is needed using just event_format, that is available
via evsel->tp_format now.

The pevent thing is per perf.data file, so I made it stop being static
and become a perf_session member, so tools processing perf.data files
use perf_session and _there_ we read the trace events description into
session->pevent and then change everywhere to stop using that single
global pevent variable and use the per session one.
Note that it _doesn't_ fall backs to trace__event_id, as we're not
interested at all in what is present in the
/sys/kernel/debug/tracing/events in the workstation doing the analysis,
just in what is in the perf.data file.
This patch also introduces perf_session__set_tracepoints_handlers that
is the perf perf.data/session way to associate handlers to tracepoint
events by resolving their IDs using the events descriptions stored in a
perf.data file. Make 'perf sched' use it.

There are unnecessary #include <ctype.h> out there, and they might cause
a nasty build failure in some environment. As we already have most of
ctype macros in util.h, just get rid of them.
A few of exceptions are util/symbol.c which needs isupper() macro util.h
doesn't provide and perl scripting support code which includes ctype.h
internally.

Reducing the exposure of perf_session further, so that we can use the
classes in cases where no perf.data file is created.

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).

Both python_scripting_ops and perl_scripting_ops have two global definitions.
One in trace-event-scripting.c and one in their respective scripting-engine
modules.
The issue is that depending on the linker order one definition or the other
is chosen. One is uninitialized (bss), while the other is initialized. If
the uninitialized version is chosen, then perf does not function properly.
This patch fixes this by adding the extern prefix to the definitions in
trace-event-scripting.c.

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.
