It's not possible to have one generic/common "struct post_socket_opts"
for all tests. It's better to have the individual test define its own
callback opts struct.
So this patch drops struct post_socket_opts, and changes the second
parameter of post_socket_cb as "void *" type.

This patch uses public helper connect_to_fd() exported in network_helpers.h
instead of the local defined function connect_to_server() in
prog_tests/sockopt_inherit.c. This can avoid duplicate code.

Include network_helpers.h in prog_tests/sockopt_inherit.c, use public
helper start_server_addr() instead of the local defined function
start_server(). This can avoid duplicate code.
Add a helper custom_cb() to set SOL_CUSTOM sockopt looply, set it to
post_socket_cb pointer of struct network_helper_opts, and pass it to
start_server_addr().

Even though it's not relevant in selftests, the people
might still copy-paste from them. So let's take care
of optlen > 4096 cases explicitly.

BPF object files are, in a way, the final artifact produced as part of
the ahead-of-time compilation process. That makes them somewhat special
compared to "regular" object files, which are a intermediate build
artifacts that can typically be removed safely. As such, it can make
sense to name them differently to make it easier to spot this difference
at a glance.
Among others, libbpf-bootstrap [0] has established the extension .bpf.o
for BPF object files. It seems reasonable to follow this example and
establish the same denomination for selftest build artifacts. To that
end, this change adjusts the corresponding part of the build system and
the test programs loading BPF object files to work with .bpf.o files.

bpf_object__find_program_by_title is going to be deprecated. Replace
all use cases in tools/testing/selftests/bpf with
bpf_object__find_program_by_name or bpf_object__for_each_program.

Migrate all the selftests that were still using bpf_prog_load_xattr().
Few are converted to skeleton, others will use bpf_object__open_file()
API.

Andrii reported that sockopt_inherit occasionally hangs up on 5.5 kernel [0].
This can happen if server_thread runs faster than the main thread.
In that case, pthread_cond_wait will wait forever because
pthread_cond_signal was executed before the main thread was blocking.
Let's move pthread_mutex_lock up a bit to make sure server_thread
runs strictly after the main thread goes to sleep.
(Not sure why this is 5.5 specific, maybe scheduling is less
deterministic? But I was able to confirm that it does indeed
happen in a VM.)

Move the files, adjust includes, remove entry from Makefile & .gitignore
I also added pthread_cond_wait for the server thread startup. We don't
want to connect to the server that's not yet up (for some reason
this existing race is now more prominent with test_progs).
