Delyan Kratunov 00389c58ff bpftool: Add support for subskeletons
Subskeletons are headers which require an already loaded program to
operate.

For example, when a BPF library is linked into a larger BPF object file,
the library userspace needs a way to access its own global variables
without requiring knowledge about the larger program at build time.

As a result, subskeletons require a loaded bpf_object to open().
Further, they find their own symbols in the larger program by
walking BTF type data at run time.

At this time, programs, maps, and globals are supported through
non-owning pointers.
