[PATCH bpf-next v2 0/2] libbpf: Extend linker API to support in-memory ELF files

[Alastair Robertson <ajor@meta.com>]

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.

v2:
- Split into two commits
- Replace non-required "name" parameters with new optional opt->filename
  field
- Implement bpf_linker__add_file/bpf_linker__add_buf on top of
  bpf_linker__add_fd
- Remove bpf_linker__finalize_fd and instead have libbpf keep track of
  whether the linker's fd is owned by the linker
