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.

4869d309e1 doc: Fix up note about missing tcpi_snd_wnd in man page
The behaviour without tcpi_snd_wnd changed: the only difference now
is the advertised window, which corresponds to the queried sending
buffer size.

675174d4ba conf, tap: Split netlink and pasta functions, allow interface configuration
Move netlink routines to their own file, and use netlink to configure
or fetch all the information we need, except for the TUNSETIFF ioctl.

Move pasta-specific functions to their own file as well, add
parameters and calls to configure the tap interface in the namespace.

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

[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]

9657b6ed05 conf, tcp: Periodic detection of bound ports for pasta port forwarding
Detecting bound ports at start-up time isn't terribly useful: do this
periodically instead, if configured.

This is only implemented for TCP at the moment, UDP is somewhat more
complicated: leave a TODO there.
