Quentin Monnet 30da46b5dc tools: bpftool: add a command to dump the trace pipe ... BPF programs can use the bpf_trace_printk() helper to print debug information into the trace pipe. Add a subcommand "bpftool prog tracelog" to simply dump this pipe to the console. This is for a good part copied from iproute2, where the feature is available with "tc exec bpf dbg". Changes include dumping pipe content to stdout instead of stderr and adding JSON support (content is dumped as an array of strings, one per line read from the pipe). This version is dual-licensed, with Daniel's permission.
