perf: Turn off compiler warnings for flex and bison generated files

We don't know what types of warnings different versions of flex
and bison combined with different versions of gcc is going to
generate, so just punt and don't warn about anything.

This fixes the build of perf for me on an openSUSE 12.1 system.

perf: Have perf use the new libtraceevent.a library

The event parsing code in perf was originally copied from trace-cmd
but never was kept up-to-date with the changes that was done there.
The trace-cmd libtraceevent.a code is much more mature than what is
currently in perf.

This updates the code to use wrappers to handle the calls to the
new event parsing code. The new code requires a handle to be pass
around, which removes the global event variables and allows
more than one event structure to be read from different files
(and different machines).

But perf still has the old global events and the code throughout
perf does not yet have a nice way to pass around a handle.
A global 'pevent' has been made for perf and the old calls have
been created as wrappers to the new event parsing code that uses
the global pevent.

With this change, perf can later incorporate the pevent handle into
the perf structures and allow more than one file to be read and
compared, that contains different events.

perf: Separate out trace-cmd parse-events from perf files

Move the trace-event-parse.c code that originally came from trace-cmd into
their own files. The new file will be called trace-parse-events.c, as
the name of trace-cmd's file was parse-events.c too, but it conflicted
with the parse-events.c file in perf that parses the command line.

This tries to update the code with mimimal changes.

Perf specific code stays in the trace-event-parse.[ch] files and
the common parsing code is now in trace-parse-events.c and
trace-parse-events.h.

perf report: Add a simple GTK2-based 'perf report' browser

This patch adds a simple GTK2-based browser to 'perf report' that's
based on the TTY-based browser in builtin-report.c.

To launch "perf report" using the new GTK interface just type:

$ perf report --gtk

The interface is somewhat limited in features at the moment:

- No callgraph support

- No KVM guest profiling support

- No color coding for percentages

- No sorting from the UI

- ..and many, many more!

That said, I think this patch a reasonable start to build future features on.

The perf python extention (perf.so) file lacks its dependencies in the
Makefile so that it cannot be refreshed if one of source files it depends
is changed. Fix it by putting them in a separate file and processing it in
both of Makefile and setup.py.

perf tools: Remove distclean from Makefile help output

distclean as an alias for clean was removed from the perf Makefile by
commit a3d1ee10d1bf4520af3d44c1aa6cd46956ec4fd7

However, that commit neglected to remove it from the help output of
the perf Makefile, which could result in a user trying the following.

$ cd tools/perf/
$ make help | grep distclean
distclean - alias to clean
$ make distclean
make: *** No rule to make target `distclean'. Stop.

This patch removes it from the Makefile help output.
