This patch defines basic interface of libbpf. 'struct bpf_object' will
be the handler of each object file. Its internal structure is hide to

patch, libelf is used to open those files, read EHDR and do basic
validation according to
Check endianess according to EHDR. Code is taken from
tools/perf/util/symbol-elf.c.
Libbpf doesn't magically convert missmatched endianess. See discussion

eBPF instructions to correct byte order, we are unable to deal with
