This patch creates maps based on 'map' section in object file using bpf_create_map(), and stores the fds into an array in 'struct bpf_object'. Previous patches parse ELF object file and collects required data, but doesn't play with the kernel. They belong to the 'opening' phase. This patch is the first patch in 'loading' phase. The 'loaded' field is introduced in 'struct bpf_object' to avoid loading an object twice, because the loading phase clears resources collected during the opening which becomes useless after loading. In this patch, maps_buf is cleared.
