95ebb37617 selftests/bpf: Convert test_global_funcs test to test_loader framework 
Convert 17 test_global_funcs subtests into test_loader framework for
easier maintenance and more declarative way to define expected
failures/successes.

c22bdd2825 selftests/bpf: Switch SEC("classifier*") usage to a strict SEC("tc") 
Convert all SEC("classifier*") uses to a new and strict SEC("tc")
section name. In reference_tracking selftests switch from ambiguous
searching by program title (section name) to non-ambiguous searching by
name in some selftests, getting closer to completely removing
bpf_object__find_program_by_title().

3e689141e6 selftests: Use consistent include paths for libbpf 
Fix all selftests to include libbpf header files with the bpf/ prefix, to
be consistent with external users of the library. Also ensure that all
includes of exported libbpf header files (those that are exported on 'make
install' of the library) use bracketed includes instead of quoted.

To not break the build, keep the old include path until everything has been
changed to the new one; a subsequent patch will remove that.

360301a6c2 selftests/bpf: Add unit tests for global functions 
test_global_func[12] - check 512 stack limit.
test_global_func[34] - check 8 frame call chain limit.
test_global_func5    - check that non-ctx pointer cannot be passed into
                       a function that expects context.
test_global_func6    - check that ctx pointer is unmodified.
test_global_func7    - check that global function returns scalar.
