1f3d6f96b5 test/lib/test: Wait a bit longer before terminating iperf3 processes 
Sometimes tests run a few seconds longer than expected, wait a few
more seconds.

6257a2752e test/perf: Try sourcing maximum scaling frequency from cpufreq 
On most recent CPUs, that's a better indication of all-core turbo
frequency, or non-turbo frequency, than /proc/cpuinfo.

12cfa6444c passt: Add clang-tidy Makefile target and test, take care of warnings 
Most are just about style and form, but a few were actually
serious mistakes (NDP-related).

087b5f4dbb LICENSES: Add license text files, add missing notices, fix SPDX tags 
SPDX tags don't replace license files. Some notices were missing and
some tags were not according to the SPDX specification, too.

Now reuse --lint from the REUSE tool (https://reuse.software/) passes.

9a175cc2ce pasta: Allow specifying paths and names of namespaces 
Based on a patch from Giuseppe Scrivano, this adds the ability to:

- specify paths and names of target namespaces to join, instead of
  a PID, also for user namespaces, with --userns

- request to join or create a network namespace only, without
  entering or creating a user namespace, with --netns-only

- specify the base directory for netns mountpoints, with --nsrun-dir

Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
[sbrivio: reworked logic to actually join the given namespaces when
 they're not created, implemented --netns-only and --nsrun-dir,
 updated pasta demo script and man page]
