By adding libbpf into perf's Makefile, this patch enables perf to build
libbpf if libelf is found and neither NO_LIBELF nor NO_LIBBPF is set.
The newly introduced code is similar to how libapi and libtraceevent
are wired into Makefile.perf.
MANIFEST is also updated for 'make perf-*-src-pkg'.
Append make_no_libbpf to tools/perf/tests/make.
The 'bpf' feature check is appended into default FEATURE_TESTS and
FEATURE_DISPLAY, so perf will check the API version of bpf in
/path/to/kernel/include/uapi/linux/bpf.h. Which should not fail except
when we are trying to port this code to an old kernel.
Error messages are also updated to notify users about the lack of BPF
support in 'perf record' if libelf is missing or the BPF API check
failed.
tools/lib/bpf is added to TAG_FOLDERS to allow us to navigate libbpf
files when working on perf using tools/perf/tags.

The auxtrace code needed by Intel PT uses the __get_cpuid() gcc builtin,
that is not present in old systems, breaking the build.
Add a test to check for that builtin and disable AUXTRACE in those
systems.

regs_query_register_offset() is a helper function which converts
register name like "%rax" to offset of a register in 'struct pt_regs',
which is required by BPF prologue generator.
PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET indicates an architecture
supports converting name of a register to its offset in 'struct
pt_regs'.
HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET is introduced as the corresponding
CFLAGS of PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET.

The Fedora 22 version of libdw requires a couple of extra libraries to

but this doesn't work for static linking. Add the needed libraries

one of the perf tests fail to compile due to BUILD_STR macro mishandling

with the following error:

Disabling libbabeltrace check by default and replacing the
NO_LIBBABELTRACE make variable with LIBBABELTRACE.
Users wanting the libbabeltrace feature need to build via:
$ make LIBBABELTRACE=1
The reason for this is that the libababeltrace interface we use (version
1.3) hasn't been packaged/released yet, thus the failing feature check
only slows down build and confuses other (non CTF) developers.

Remove libbabeltrace check from default features set, because the
requested version is not released yet in most distributions. We'll
enable later.
Calling libbabeltrace check manually via feature_check before
$(feature-libbabeltrace) is used.

Commit b11db6581b ("perf tools: Fix build
error on ARCH=i386/x86_64/sparc64") uses sed on ARCH, which triggers a
bug in sequence of sed expression, where 's/arm.*/arm/' will replace
'arm64' to 'arm', causes arm64 building failure.
This patch prevent 'arm64' to be mached for 'arm.*' case.

Following patch added -Werror for feature builds:
b49f1a4be7 perf tools: Improve feature test debuggability
and exposed a problem in the libbabeltrace feature build, because it was
including wrong header and gcc couldn't find the used symbol definition.
Adding proper header and keeping the old one as it is needed also
(libbabeltrace quirk).

Certain feature tests fail with link errors:
triton:~/tip/tools/perf/config/feature-checks> make test-libbabeltrace.bin
gcc -MD -o test-libbabeltrace.bin test-libbabeltrace.c # -lbabeltrace provided by
/tmp/cc6dRSqd.o: In function `main':
test-libbabeltrace.c:(.text+0xf): undefined reference to `bt_ctf_stream_class_get_packet_context_type'
although they should already fail with a build error due to lack of a
proper prototype for the function. Due to this I first tried to find
which library was missing - while it was the whole feature that was
missing from the .h file already.
To solve this, propagate -Wall -Werror to all testcases and remove them
from testcase Makefile rules that used them explicitly.
A missing feature now outputs:

This message:
Makefile:153: The path 'python-config' is not executable.
Appears on every perf build that does not have a sufficient python
environment installed. It's really just an internal detail of python
configuration pass and users should not see it - and it's pretty
meaningless to them in any case because the message is not very helpful.
(So it's not executable. Why does that matter? What can the user do
about it?)
Remove the warning, the missing python feature warning is sufficient:
config/Makefile:566: No python-config tool was found
config/Makefile:566: Python support will not be built
although even that one isn't very helpful to users: so no Python support
will be built, what can the user do to fix that? Most other such
warnings give package install suggestions.

He Kuang reported that current perf tools failed to build when ARCH
variable was given like above.
It was because the name is different that internal directory name. I
can see that David's sparc64 build has same problem.
So fix it by applying the sed conversion script to the command line ARCH
variable also, and fixing the converted name there (i.e. i386/x86_64 ->
x86, sparc64 -> sparc).

Adding 'perf data convert' to convert perf data file into different
format. This patch adds support for CTF format conversion.
To convert perf.data into CTF run:
$ perf data convert --to-ctf=./ctf-data/
[ perf data convert: Converted 'perf.data' into CTF data './ctf-data/' ]
[ perf data convert: Converted and wrote 11.268 MB (100230 samples) ]
The command will create CTF metadata out of perf.data file (or one
specified via -i option) and then convert all sample events into single
CTF stream.
Each sample_type bit is translated into separated CTF event field apart
from following exceptions:
PERF_SAMPLE_RAW - added in next patch
PERF_SAMPLE_READ - TODO
PERF_SAMPLE_CALLCHAIN - TODO
PERF_SAMPLE_BRANCH_STACK - TODO
PERF_SAMPLE_REGS_USER - TODO
PERF_SAMPLE_STACK_USER - TODO
$ perf --debug=data-convert=2 data convert ...
The converted CTF data could be analyzed by CTF tools, like babletrace
or tracecompass [1].
$ babeltrace ./ctf-data/

The following members to the ctf-environment were decided to be added to
distinguish and specify perf CTF data:
- domain
It says "kernel" because it contains a kernel trace (not to be
confused with a user space like lttng-ust does)
- tracer_name
It says perf. This can be used to distinguish between lttng and perf
CTF based trace.
- version
The kernel version from stream. In addition to release, this is what
it looks like on a Debian kernel:
release = "3.14-1-amd64";
version = "3.14.0";

The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE
must be defined before pthread.h is included in order to get the proper
function declaration. Define this in the Makefile.
Without this defined, the feature check fails on a Fedora system with
gcc5 and then the perf build later fails with conflicting prototypes for
the function.
