[PATCH bpf-next v3 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.

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.
