[bpf-next,0/3] migrate from bpf_prog_test_run{,_xattr}

Message

Fairly straight-forward mechanical transformation from bpf_prog_test_run
and bpf_prog_test_run_xattr to the bpf_prog_test_run_opts goodness.
Most of the changes are in tests, though bpftool and libbpf (xsk.c) have one
call site each as well.

The only aspect that's still a bit RFC is that prog_run_xattr is testing
behavior specific to bpf_prog_test_run_xattr, which does not exist in prog_run_opts.
Namely, -EINVAL return on data_out == NULL && data_size_out > 0.
Adding this behavior to prog_test_run_opts is one option, keeping the test as-is
and cloning it to use bpf_prog_test_run_opts is another possibility.
The current version just suppresses the deprecation warning.

As an aside, checkpatch really doesn't like that LIBBPF_OPTS looks like
a function call but is formatted like a struct declaration. If anyone
cares about formatting, now would be a good time to mention it.

Delyan Kratunov (3):
  selftests: bpf: migrate from bpf_prog_test_run{,_xattr}
  bpftool: migrate from bpf_prog_test_run_xattr
  libbpf: Deprecate bpf_prog_test_run_xattr and bpf_prog_test_run
