e4e284a8c0 selftests/bpf: Redo the switch to new libbpf XDP APIs 
Switch to using new bpf_xdp_*() APIs across all selftests. Take
advantage of a more straightforward and user-friendly semantics of
old_prog_fd (0 means "don't care") in few places.

This is a redo of 544356524dd6 ("selftests/bpf: switch to new libbpf XDP
APIs"), which was previously reverted to minimize conflicts during bpf
and bpf-next tree merge.

cbdb1461dc selftests/bpf: Use explicit bpf_prog_test_load() calls everywhere 
-Dbpf_prog_load_deprecated=bpf_prog_test_load trick is both ugly and
breaks when deprecation goes into effect due to macro magic. Convert all
the uses to explicit bpf_prog_test_load() calls which avoid deprecation
errors and makes everything less magical.

c6c111523d selftests/bpf: Check for correct program attach/detach in xdp_attach test 
David Ahern noticed that there was a bug in the EXPECTED_FD code so
programs did not get detached properly when that parameter was supplied.
This case was not included in the xdp_attach tests; so let's add it to be
sure that such a bug does not sneak back in down.
