This patch implements the core logic for BPF CO-RE offsets relocations.
Every instruction that needs to be relocated has corresponding
bpf_offset_reloc as part of BTF.ext. Relocations are performed by trying
to match recorded "local" relocation spec against potentially many
compatible "target" types, creating corresponding spec. Details of the
algorithm are noted in corresponding comments in the code.

Add support for BPF CO-RE offset relocations. Add section/record
iteration macros for .BTF.ext. These macro are useful for iterating over
each .BTF.ext record, either for dumping out contents or later for BPF
CO-RE relocation handling.
To enable other parts of libbpf to work with .BTF.ext contents, moved
a bunch of type definitions into libbpf_internal.h.

Use open_memstream to override stdout during test execution.
The copy of the original stdout is held in env.stdout and used
to print subtest info and dump failed log.
test_{v,}printf are now simple wrappers around stdout and will be
removed in the next patch.

* fix -v crash by always setting env.std{in,err} (Alexei Starovoitov)
* drop force_log check from stdio_hijack (Andrii Nakryiko)
v4:
* one field per line for stdout/stderr (Andrii Nakryiko)
v3:
* don't do strlen over log_buf, log_cnt has it already (Andrii Nakryiko)
v2:
* add ifdef __GLIBC__ around open_memstream (maybe pointless since
we already depend on glibc for argp_parse)
* hijack stderr as well (Andrii Nakryiko)
* don't hijack for every test, do it once (Andrii Nakryiko)
* log_cap -> log_size (Andrii Nakryiko)
* do fseeko in a proper place (Andrii Nakryiko)

Change BPF selftest test_xdp_vlan.sh to (default) use generic XDP.
This selftest was created together with a fix for generic XDP, in commit
297249569932 ("net: fix generic XDP to handle if eth header was
mangled"). And was suppose to catch if generic XDP was broken again.
The tests are using veth and assumed that veth driver didn't support
native driver XDP, thus it used the (ip link set) 'xdp' attach that fell
back to generic-XDP. But veth gained native-XDP support in 948d4f214fde
("veth: Add driver XDP"), which caused this test script to use
native-XDP.

'flow offload' expression should not offload flows that will be subject
to ipsec, but it does.
This results in a connectivity blackhole for the affected flows -- first
packets will go through (offload happens after established state is
reached), but all remaining ones bypass ipsec encryption and are thus
discarded by the peer.
This can be worked around by adding "rt ipsec exists accept"
before the 'flow offload' rule matches.
This test case will fail, support for such flows is added in
next patch.

Add nettest - a simple program with an implementation for various networking
APIs. nettest is used for tcp, udp and raw functional tests for both IPv4
and IPv6.
Point of this command versus existing utilities:
- controlled implementation of the APIs and the order in which they
are called,
- ability to verify ingress device, local and remote addresses,
- timeout for controlled test length,
- ability to discriminate a timeout from a system call failure, and
- simplicity with test scripts.
The command returns:
0 on success,
1 for any system call failure, and
2 on timeout.

On my laptop most memcg kselftests were being skipped because it claimed
cgroup v2 hierarchy wasn't mounted, but this isn't correct. Instead, it
seems current systemd HEAD mounts it with the name "cgroup2" instead of
"cgroup":
% grep cgroup /proc/mounts
cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0
I can't think of a reason to need to check fs_spec explicitly
since it's arbitrary, so we can just rely on fs_vfstype.
After these changes, `make TARGETS=cgroup kselftest` actually runs the
cgroup v2 tests in more cases.

introduced backwards-compatibility issue, manifesting itself as -E2BIG
error returned on program load due to unknown non-zero btf_fd attribute
value for BPF_PROG_LOAD sys_bpf() sub-command.
This patch fixes bug by ensuring that we only ever associate BTF FD with
program if there is a BTF.ext data that was successfully loaded into
kernel, which automatically means kernel supports func_info/line_info
and associated BTF FD for progs (checked and ensured also by BTF
sanitization code).

Having static variable `cpus` in libbpf_num_possible_cpus function
without guarding it with mutex makes this function thread-unsafe.
If multiple threads accessing this function, in the current form; it
leads to incrementing the static variable value `cpus` in the multiple

* added stack variable to calculate cpus
* serialized static variable update using WRITE_ONCE()
