A new API function is added to libbpf in order to pass the log_level from bpftool with the bpf_object__* part of the API. Options for a finer control over the log levels to use for libbpf and the verifier could be added in the future, if desired. v3: - Fix and clarify commit logs. v2: - Do not add distinct options for libbpf and verifier logs, just keep the one that sets all log levels to their maximum. Rename the option. - Do not offer a way to pick desired log levels. The choice is "use the option to print all logs" or "stick with the defaults". - Do not export BPF_LOG_* flags to user header. - Update all man pages (most bpftool operations use libbpf and may print libbpf logs). Verifier logs are only used when attempting to load programs for now, so bpftool-prog.rst and bpftool.rst remain the only pages updated in that regard.
