Merge reason: this topic is ready now to merge into the main
development branch for .32, with functional
perf trace output.

The _XOPEN_SOURCE* defines are not really needed on Linux and
it's not like we'll port this to AIX ;-)
The define also broke the build with gcc 4.4.1:
CC util/trace-event-parse.o
In file included from util/trace-event-parse.c:32:
util/util.h:43:1: error: "_XOPEN_SOURCE" redefined
So remove them.

This adds perf trace into the set of perf tools.
It is written to fetch the tracepoint samples from perf events
and display them, according to the events information given by
the debugfs files through the util/trace* tools.
It is a rough first shot and doesn't yet handle the cpu,
timestamps fields and some other things.
Example:
perf record -f -e workqueue:workqueue_execution:record -F 1 -a
perf trace

Add support to 'perf list' and 'perf stat' for kernel tracepoints. The
implementation creates a 'for_each_subsystem' and 'for_each_event' for
easy iteration over the tracepoints.

Vince Weaver reported that there's a handful of #ifdef __MINGW32__
sections in the code.
Remove them as they are in essence dead code - as unlike upstream
Git, the perf tool is unlikely to be ported to Windows.

Introduce isprint() to print out raw event dumps to ASCII, etc.

The Git utils came with a ctype replacement that doesn't provide
isprint(). Add a replacement.
Solves a build bug on certain distros.

Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.
