2020-01-20samples/bpf: Use consistent include paths for libbpfToke Høiland-Jørgensen
Fix all files in samples/bpf 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 make sure no new files are introduced that doesn't include the bpf/ prefix in its include, remove tools/lib/bpf from the include path entirely, and use tools/lib instead.

2019-11-08samples: bpf: update map definition to new syntax BTF-defined mapDaniel T. Lee
Since, the new syntax of BTF-defined map has been introduced, the syntax for using maps under samples directory are mixed up. For example, some are already using the new syntax, and some are using existing syntax by calling them as 'legacy'. As stated at commit abd29c931459 ("libbpf: allow specifying map definitions using BTF"), the BTF-defined map has more compatablility with extending supported map definition features. The commit doesn't replace all of the map to new BTF-defined map, because some of the samples still use bpf_load instead of libbpf, which can't properly create BTF-defined map. This will only updates the samples which uses libbpf API for loading bpf program. (ex. bpf_prog_load_xattr) Signed-off-by: Daniel T.
