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.
