Some of XDP samples that are attaching the bpf program to the interface
via libbpf's bpf_set_link_xdp_fd are still using the bpf_load.c for
loading and manipulating the ebpf program and maps. Convert them to do
this through libbpf usage and remove bpf_load from the picture.

While at it remove what looks like debug leftover in
xdp_redirect_map_user.c

In xdp_redirect_cpu, change the way that the program to be loaded onto
interface is chosen - user now needs to pass the program's section name
instead of the relative number. In case of typo print out the section
names to choose from.

Thanks a lot for converting sample/bpf programs to use libbpf.  It have
been on my todo list for a very long time.

You didn't implement the matching of prog-names in a iproute2 like
fashion, as I described, but the important part was converting this to
libbpf, so I'll Ack this anyway.
I will post it as a follow-up patch once I'm done with this series and we got
this (hopefully) merged, if you don't mind.

Thank you!
(I acked V1 just before... meant to ACK this V3)
