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.

Commit 7f5f873c6a ("rculist: Use WRITE_ONCE() when deleting from
reader-visible list") added the use of the WRITE_ONCE macro to the
kernel version of list.h, which broke the stacktool build because the
tools list.h includes the kernel list.h.
Avoid this type of situation in the future and make list.h
self-sufficient by copying the kernel list.h routines directly into
tools list.h.
This is a straight copy except for adjustments to the include statements
and copying of the tools-specific list routines (list_del_range and
list_for_each_from).

The reason is READ_ONCE/WRITE_ONCE code we took from kernel sources. They
intentionaly break aliasing rules. While this is ok for kernel because it's
built with -fno-strict-aliasing, it breaks perf which is build with
-Wstrict-aliasing=3.

used in the tools/arch/*/include/asm/barrier.h files that are being
introduced now.

We need to use lib/hweight.c for that, just like we do for lib/rbtree.c,
so tools need to link hweight.o. For now do it directly, but we need to
have a tools/lib/lk.a or .so that collects these goodies...

Will be used to make sure we pass a power of two when automatically
setting up the perf_mmap addr range length, as the kernel code
validating input on /proc/sys/kernel/perf_event_mlock_kb accepts any
integer, if we plain use it to set up the mmap lenght, we may get an
EINVAL when passing a non power of two.

So tools/ has been growing three, at a different stage of their
development export.h headers and so we should unite into one. Add
tools/include/ to the include path of virtio and liblockdep to pick the
shared header now.
