Quentin says:
This series introduces support for JSON output to all bpftool commands. It
adds option parsing, and several options are created:
* -j, --json Switch to JSON output.
* -p, --pretty Switch to JSON and print it in a human-friendly fashion.
* -h, --help Print generic help message.
* -V, --version Print version number.
This code uses a "json_writer", which is a copy of the one written by
Stephen Hemminger in iproute2.

I don't know if there is an easy way to share the code for json_write
without copying the file, so I am very open to suggestions on this matter.
