selftests/bpf: Fix pkg-config call on static builds

For commit b0dcdcb9ae75 ("resolve_btfids: Fix linker flags detection"),
I suggested setting HOSTPKG_CONFIG to $PKG_CONFIG when compiling
resolve_btfids, but I forgot the quotes around that variable.

As a result, when running vmtest.sh with static linking, it fails as
follows:

$ LDLIBS=-static PKG_CONFIG='pkg-config --static' ./vmtest.sh
[...]
make: unrecognized option '--static'
Usage: make [options] [target] ...
[...]

This worked when I tested it because HOSTPKG_CONFIG didn't have a
default value in the resolve_btfids Makefile, but once it does, the
quotes aren't preserved and it fails on the next make call.

resolve_btfids: Fix linker flags detection

The "|| echo -lzstd" default makes zstd an unconditional link
dependency of resolve_btfids. On systems where libzstd-dev is not
installed and pkg-config fails, the linker fails:

ld: cannot find -lzstd: No such file or directory

libzstd is a transitive dependency of libelf, so the -lzstd flag is
strictly necessary only for static builds [1].

Remove ZSTD_LIBS variable, and instead set LIBELF_LIBS depending on
whether the build is static or not. Use $(HOSTPKG_CONFIG) as primary
source of the flags list.

Also add a default value for HOSTPKG_CONFIG in case it's not built via
the toplevel Makefile. Pass it from selftests/bpf too.

This series includes various fixes aiming to enable test_progs run
with userspace address sanitizer on BPF CI.

The first five patches add a simplified implementation of strscpy() to
selftests/bpf and then replace strcpy/strncpy usages across the tests
with it. See relevant discussions [1][2].

Patch #6 fixes the selftests/bpf/test_progs build with:

SAN_CFLAGS="-fsanitize=address -fno-omit-frame-pointer"

The subsequent patches fix bugs reported by the address sanitizer on
attempt to run the tests.

selftests/bpf: Pass through build flags to bpftool and resolve_btfids

EXTRA_* and SAN_* build flags were not correctly propagated to bpftool
and resolve_btids when building selftests/bpf. This led to various
build errors on attempt to build with SAN_CFLAGS="-fsanitize=address",
for example.

Fix the makefiles to address this:
- Pass SAN_CFLAGS/SAN_LDFLAGS to bpftool and resolve_btfids build
- Propagate EXTRA_LDFLAGS to resolve_btfids link command
- Use pkg-config to detect zlib and zstd for resolve_btfids, similar
libelf handling

Also check for ASAN flag in selftests/bpf/Makefile for convenience.

selftests/bpf: Remove hexdump dependency

The verification signature header generation requires converting a
binary certificate to a C array. Previously this only worked with xxd,
and a switch to hexdump has been done in commit b640d556a2b3
("selftests/bpf: Remove xxd util dependency").

hexdump is a more common utility program, yet it might not be installed
by default. When it is not installed, BPF selftests build without
errors, but tests_progs is unusable: it exits with the 255 code and
without any error messages. When manually reproducing the issue, it is
not too hard to find out that the generated verification_cert.h file is
incorrect, but that's time consuming. When digging the BPF selftests
build logs, this line can be seen amongst thousands others, but ignored:

/bin/sh: 2: hexdump: not found

Here, od is used instead of hexdump. od is coming from the coreutils
package, and this new od command produces the same output when using od
from GNU coreutils, uutils, and even busybox. This is more portable, and
it produces a similar results to what was done before with hexdump:
there is an extra comma at the end instead of trailing whitespaces,
but the C code is not impacted.

selftests/bpf: Remove xxd util dependency

The verification signature header generation requires converting a
binary certificate to a C array. Previously this only worked with
xxd (part of vim-common package).
As xxd may not be available on some systems building selftests, it makes
sense to substitute it with more common utils: hexdump, wc, sed to
generate equivalent C array output.

Tested by generating header with both xxd and hexdump and comparing
them.

selftests/bpf: convert test_bpftool_metadata.sh into test_progs framework

The test_bpftool_metadata.sh script validates that bpftool properly
returns in its ouptput any metadata generated by bpf programs through
some .rodata sections.

Port this test to the test_progs framework so that it can be executed
automatically in CI. The new test, similarly to the former script,
checks that valid data appears both for textual output and json output,
as well as for both data not used at all and used data. For the json
check part, the expected json string is hardcoded to avoid bringing a
new external dependency (eg: a json deserializer) for test_progs.
As the test is now converted into test_progs, remove the former script.

The newly converted test brings two new subtests:

#37/1 bpftool_metadata/metadata_unused:OK
#37/2 bpftool_metadata/metadata_used:OK
#37 bpftool_metadata:OK
Summary: 1/2 PASSED, 0 SKIPPED, 0 FAILED

selftests/bpf: Add a few helpers for bpftool testing

In order to integrate some bpftool tests into test_progs, define a few
specific helpers that allow to execute bpftool commands, while possibly
retrieving the command output. Those helpers most notably set the
path to the bpftool binary under test. This version checks different
possible paths relative to the directories where the different
test_progs runners are executed, as we want to make sure not to
accidentally use a bootstrap version of the binary.

regulator: core: allow regulator_register() with

Merge series from André Draszik <andre.draszik@linaro.org>:

With these attached patches it becomes possible again to support
hardware designs with multiple PMICs where individual rails of each act
as required supplies for rails of the other (due to the latter being
e.g. always-on), and vice-versa.

Google Pixel 6 and 6 Pro (oriole and raven) are examples of such
designs.

Rather than returning -EPORBE_DEFER in regulator_register() when
set_machine_constraints() fails with -EPROBE_DEFER (due to missing
required supplies), we still allow rail registration and try to
reresolve supplies each time a new rail gets registered.

This is implemented using a bus (regulator bus), which allows the core
to reresolve supplies for regulators that still need them whenever new
regulators (i.e. devices) are added.

Using a bus also solves existing problems around late resolution of
supplies as mentioned in the commit message introducing that bus.

The series starts with a few bug fixes and the last two commits
implement the changes mentioned above, but do depend on the bug fixes.
