We need bpftool and required kernel/bpf/disasm.[ch] to bootstrap the
cgroups, bperf and other BPF skels used by perf.

Add list_sort.[ch] from the main kernel tree. The linux/bug.h #include
is removed due to conflicting definitions. Add check-headers and modify
perf build accordingly.
MANIFEST and python-ext-sources fixes suggested by Arnaldo.

$ make -C tools/perf build-test
does, ends up with these two problems:
make[3]: *** No rule to make target '/tmp/tmp.zq13cHILGB/perf-5.3.0/include/uapi/linux/bpf.h', needed by 'bpf_helper_defs.h'. Stop.
make[3]: *** Waiting for unfinished jobs....
make[2]: *** [Makefile.perf:757: /tmp/tmp.zq13cHILGB/perf-5.3.0/tools/lib/bpf/libbpf.a] Error 2
make[2]: *** Waiting for unfinished jobs....
Because $(srcdir) points to the /tmp/tmp.zq13cHILGB/perf-5.3.0 directory
and we need '/tools/ after that variable, and after fixing this then we
get to another problem:
/bin/sh: /home/acme/git/perf/tools/scripts/bpf_helpers_doc.py: No such file or directory
make[3]: *** [Makefile:184: bpf_helper_defs.h] Error 127
make[3]: *** Deleting file 'bpf_helper_defs.h'
LD /tmp/build/perf/libapi-in.o
make[2]: *** [Makefile.perf:778: /tmp/build/perf/libbpf.a] Error 2
make[2]: *** Waiting for unfinished jobs....
Because this requires something outside the tools/ directories that gets
collected into perf's detached tarballs, to fix it just add it to
tools/perf/MANIFEST, which this patch does, now it works for that case
and also for all these other cases.

This came from the kernel lib/argv_split.c, so move it to
tools/lib/argv_split.c, to get it closer to the kernel structure.
We need to audit the usage of argv_split() to figure out if it is really
necessary to do have one allocation per argv[] entry, looking at one of
its users I guess that is not the case and we probably are even leaking
those allocations by not using argv_free() judiciously, for later.
With this we further remove stuff from tools/perf/util/, reducing the
perf specific codebase and encouraging other tools/ code to use these
routines so as to keep the style and constructs used with the kernel.

We got the sane_ctype.h headers from git and kept using it so far, but
since that code originally came from the kernel sources to the git
sources, perhaps its better to just use the one in the kernel, so that
we can leverage tools/perf/check_headers.sh to be notified when our copy
gets out of sync, i.e. when fixes or goodies are added to the code we've
copied.
This will help with things like tools/lib/string.c where we want to have
more things in common with the kernel, such as strim(), skip_spaces(),
etc so as to go on removing the things that we have in tools/perf/util/
and instead using the code in the kernel, indirectly and removing things
like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements
are made to the original code.
Hopefully this also should help with reducing the difference of code
hosted in tools/ to the one in the kernel proper.

Now that I'm switching the container builds from using a local volume
pointing to the kernel repository with the perf sources, instead getting
a detached tarball to be able to use a container cluster, some places
broke because I forgot to put some of the required files in
tools/perf/MANIFEST, namely some bitsperlong.h files.
So, to fix it do the same as for tools/build/ and pack the whole
tools/arch/ directory.

So that we can build on older systems where otherwise we would end up
with:
CC /tmp/build/perf/trace/beauty/ioctl.o
trace/beauty/ioctl.c: In function 'ioctl__scnprintf_tty_cmd':

trace/beauty/ioctl.c:25:2: error: array index in initializer not of integer type
trace/beauty/ioctl.c:25:2: error: (near initialization for 'ioctl_tty_cmd')
This way we can build a tool on an older system and it will still be
capable of processing perf.data files generated on newer systems.

We shouldn't use headers from the kernel sources directly, instead we
should use the system's headers or in cases where that isn't possible,
like with perf_event.h, where the introduction of kernel features such
as perf_event_attr.{write_backwards,sample_max_stack} and
PERF_EVENT_IOC_PAUSE_OUTPUT take some time to become available in
/usr/include/linux/perf_event.h we need a copy.
Do it and check for source code drift, emitting a warning when changes
are detected.

The tools so far have been using the strerror_r() GNU variant, that
returns a string, be it the buffer passed or something else.
But that, besides being tricky in cases where we expect that the
function using strerror_r() returns the error formatted in a provided
buffer (we have to check if it returned something else and copy that
instead), breaks the build on systems not using glibc, like Alpine
Linux, where musl libc is used.
So, introduce yet another wrapper, str_error_r(), that has the GNU
interface, but uses the portable XSI variant of strerror_r(), so that
users rest asured that the provided buffer is used and it is what is
returned.

The commit that introduced it should've moved it to the same place, plus
the 'tools/' prefix, but instead moved it to a bogus tools/lib/util/
directory, being the only file there.
Move it to tools/lib/find_bit.c, picking the name for the file where
these routines live since:
8f6f19dd5143 ("lib: move find_last_bit to lib/find_next_bit.c")
Next step is to make tools/lib/find_bit.c to differ from lib/find_bit.c
just in removing what is not used by tools/.

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.

This patch copies filter.h from include/linux/kernel.h to
tools/include/linux/filter.h to enable other libraries to use macros in it,
like libbpf which will be introduced by further patches.
Currently, the filter.h copy only contains the useful macros needed by
libbpf for not introducing too much dependence.
tools/perf/MANIFEST is also updated for 'make perf-*-src-pkg'.
One change:
The 'imm' field of BPF_EMIT_CALL becomes ((FUNC) - BPF_FUNC_unspec) to
suit user space code generator.
