/* 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
