This gives API consumers the option of using anonymous files/memfds to avoid writing temporary ELFs to disk, which will be useful for performing linking as part of bpftrace's JIT compilation. v3: - Removed "filename" option. Now always generate our own filename for passed-in FDs and buffers. - Use a common function (bpf_linker_add_file) for shared implementation of bpf_linker__add_file, bpf_linker__add_fd and bpf_linker__add_buf.
