Subject: [PATCH net-next 00/12] tools: bpftool: Add JSON output to bpftool

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.
