/* parses elf file compiled by llvm .c->.o
* . parses 'maps' section and creates maps via BPF syscall
* . parses 'license' section and passes it to syscall
* . parses elf relocations for BPF maps and adjusts BPF_LD_IMM64 insns by
* storing map_fd into insn->imm and marking such insns as BPF_PSEUDO_MAP_FD
* . loads eBPF programs via BPF syscall
* One ELF file can contain multiple BPF programs which will be loaded
* and their FDs stored stored in prog_fd array
* returns zero on success
