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.

perf tools: Add perf pmu object to access pmu format definition

Adding pmu object which provides interface to pmu's sysfs
event format definition located at:
${sysfs_mount}/bus/event_source/devices/${pmu}/format

Following interface is exported:
struct perf_pmu* perf_pmu__find(char *name);
- this function returns pmu object, which is then
passed as a handle to other interface functions

int perf_pmu__config(struct perf_pmu *pmu, struct perf_event_attr *attr,
struct list_head *head_terms);
- this function configures perf_event_attr struct based
on pmu's format definitions and config terms data,
containined in head_terms list.

Parser generator is used to retrive the pmu's format definition.
The generated parser is part of the patch. Added makefile rule
'pmu-parser' to generate the parser code out of the bison/flex
sources.

Added builtin test 'Test perf pmu format parsing', which could
be run like:
perf test pmu

perf tools, x86: Build perf on older user-space as well

On ancient systems I get this build failure:

util/../../../arch/x86/include/asm/unistd.h:67:29: error: asm/unistd_64.h: No such file or directory
In file included from util/cache.h:7,

util/../perf.h: In function ‘sys_perf_event_open’:In file included from util/../perf.h:16
perf.h:170: error: ‘__NR_perf_event_open’ undeclared (first use in this function)

The reason is that this old system does not have the split
unistd.h headers yet, from which to pick up the syscall
definitions.

Add the syscall numbers to the already existing i386 and x86_64
blocks in perf.h, and also provide empty include file stubs.

With this patch perf builds and works fine on 5 years old
user-space as well.

However, that commit neglected to remove it from the help output of

$ cd tools/perf/
$ make help | grep distclean
distclean - alias to clean
$ make distclean

perf tools: Fix broken build by defining _GNU_SOURCE in Makefile

When building on my Debian/mips system, util/util.c fails to build
because commit 1aed2671738785e8f5aea663a6fda91aa7ef59b5 (perf kvm: Do
guest-only counting by default) indirectly includes stdio.h before the
feature selection in util.h is done. This prevents _GNU_SOURCE in
util.h from enabling the declaration of getline(), from now second
inclusion of stdio.h, and the build is broken.

There is another breakage in util/evsel.c caused by include ordering,
but I didn't fully track down the commit that caused it.

The root cause of all this is an inconsistent definition of _GNU_SOURCE,
so I move the definition into the Makefile so that it is passed to all
invocations of the compiler and used uniformly for all system header
files. All other #define and #undef of _GNU_SOURCE are removed as they
cause conflicts with the definition passed to the compiler.

All the features.h definitions (_LARGEFILE64_SOURCE _FILE_OFFSET_BITS=64
and _GNU_SOURCE) are needed by the python glue code too, so they are
moved to BASIC_CFLAGS, and the misleading comments about BASIC_CFLAGS
are removed.

This gives me a clean build on x86_64 (fc12) and mips (Debian).

perf top: Reuse the 'report' hist_entry/hists classes

This actually fixes several problems we had in the old 'perf top':

1. Unresolved symbols not show, limitation that came from the old
"KernelTop" codebase, to solve it we would need to do changes
that would make sym_entry have most of the hist_entry fields.
2. It was using the number of samples, not the sum of sample->period.

And brings the --sort code that allows us to have all the views in
'perf report', for instance:

All the filter lists can be used as well: --dsos, --comms, --symbols,

This change will allow multiple simplifications in the symbol system as
well, that will be detailed in upcoming changesets.

perf tools: Add support for disabling -Werror via WERROR=0

GCC often introduces new warnings with lots of false positives -
breaking -Werror builds. WERROR=0 allows one to build perf without much
fuss - while still encouraging people to send patches to avoid the fuss
of having to type WERROR=0.

Bisecting back to commits that produce a (mostly harmless) warning on
some compilers is more difficult. With WERROR=0 one could bisect without
worrying about harmless warnings.

The problem is the detection of the host arch without considering passed in
flags. This change fixes 32-bit builds via:

make EXTRA_CFLAGS=-m32

and 64-bit builds still reference the memcpy_64.S.

tools/perf: Fix static build of perf tool

To build a statically linked version of the perf tool all needed
libraries must be added in the correct order to get the symbols
resolved. Currently this is broken when, e.g. python or newt
support is enabled -- libpython needs libpthread which is an
unconditional link dependency of the perf tool; libslang needs
libm, another unconditional dependency. To solve the problem in
the long run without the need to keep track of transitive
library dependencies, simply make the linker look at the EXTLIBS
multiple times until it has all symbols resolved.
