Some recent change to xenial-updates broke dependencies for gcc,
it can't be installed anymore. Skipping apt-get update leaves gcc
dependencies in a consistent state, though.

The shell might report 'nc -6 -l -p 9999 > /tmp/ns_msg' as done
even after the subsequent 'echo' is done: wait one second before
reading out /tmp/ns_msg, to ensure we read that instead of the
"Done" message.

The new tests check build and a simple case with pasta sending a
short message in both directions (namespace to init, init to
namespace).
Tests cover a mix of Debian, Fedora, OpenSUSE and Ubuntu combinations
on aarch64, i386, ppc64, ppc64le, s390x, x86_64.
Builds tested starting from approximately glibc 2.19, gcc 4.7, and
actual functionality approximately from 4.4 kernels, glibc 2.25,
gcc 4.8, all the way up to current glibc/gcc/kernel versions.

For distribution tests, we'll repeat some tests frequently. Add a
'def' directive that starts a block, ended by 'endef', whose
execution can then be triggered by simply giving its name as a
directive itself.

We might have highlighting and slightly different prompts across
different distributions, allow a more reasonable set of prompt
strings to be accepted as prompts.

The throughput results in this test look quite variable, slightly
lower figures look reasonable anyway.

Debug information might be printed after a prompt is seen,
just wait those 3 seconds and be done with it.

An inline comment prefixed by a space doesn't mean the space
is dropped, and sleep(1) will get a blank in its argument.
Move the comment on its own line.

They'll start DAD as we bring up the interface, and the DHCPv6
client might be unreasonably delayed if we start it too early.

With recent improvements, we're not CPU-bound at all while testing
UDP performance. Give the VM more memory and CPUs, forward two
additional ports, start up to four threads in parallel, and give
single iperf3 threads higher bandwidth targets.

On most recent CPUs, that's a better indication of all-core turbo
frequency, or non-turbo frequency, than /proc/cpuinfo.

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.

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

[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]
