Subject: [PATCH bpf-next 0/3] Skeleton improvements and documnetation

Simplify skeleton usage by embedding source BPF object file inside skeleton
itself. This allows to keep skeleton and object file in sync at all times with
no chance of confusion.

Also, add bpftool-gen.rst manpage, explaining concepts and ideas behind
skeleton. In examples section it also includes a complete small BPF
application utilizing skeleton, as a demonstration of API.

Patch #2 also removes BPF_EMBED_OBJ, as there is currently no use of it.

Andrii Nakryiko (3):
  bpftool, selftests/bpf: embed object file inside skeleton
  libbpf: remove BPF_EMBED_OBJ macro from libbpf.h
  bpftool: add gen subcommand manpage
