bash-completion: add bits to dist tarball
The bits command was added in commit 6e1301d59 (text-utils: add bits
command) but the bash-completion file was not added to the autotools
Makemodule.am, causing it to be missing from release tarballs.
This resulted in meson build failures when using the tarball with
bash-completion installed, as meson.build references the file but
it doesn't exist in the tarball.

The current \4 and \6 issue file escapes implementation is inferior. It
uses get getifaddrs() to get a list of IP addresses. This function does not
provide enough information to discriminate between stable IP addresses and
ephemeral addresses. As a result, especially \6 often gives unreliable
results.
The code is actually unable to get list of all interfaces, so a proper out
of the box IP address reporting depends on external tools that generate
issue file with the interfaces list.
The netlink messages are already used, but only as a change notifier. The
contents is not used, even if it contains exact information about the
change. As a result, change processing is triggered even for unrelated
network changes like IPv6 router advertisement.
The new implementation uses the new netaddrq library. It reports more
reliable results especially for IPv6.
Additionally, two new escapes are implemented:
\a Report all interfaces and assigned addresses that are considered as
reliable.
\A Report all interfaces and all assigned addresses.
TODO:
To prevent overflooding of the console, the list is currently limited to 12
interfaces. It would be nice to make it configurable.
Two pass processing of issue files. First pass just collects IP protocols
and list of interfaces (in future interface patterns). Now it always
processes both IPv4 and IPv6 on all interfaces. Not so bad, as \a is smart
enough to display just the useful part.
Maybe implement more options and formatting support for \a and \A.
Maybe implement interface filter globs or regexps for \a and \A. Still not
so bad, as \a automatically skips interfaces without reliable addresses
(e. g. lo or TUN).
To support netlink and IP address processing, two new library files were
added:
netlink: Generic netlink message processing code converting netlink
messages to calls of callbacks with a pre-processed data.
netaddrq: A code that gets and maintains linked list of the current
interfaces and assigned IP addresses. It also provides a rating of IP
addresses based on its "quality", i. e. type of address, validity, lifetime
etc.

libfdisk can wipe the unwanted signature only when creating a new

kill: add support for race-free process kills using pidfd inodes
The 6.9 Linux kernel added support for pidfds which introduces inodes
that stay unique for the system lifetime and can be used to reference
a process with both its traditional pid and pid fd inode number.
This enables race-free killing of processes and protects from false
referencing due to pid rollovers.
This patch adds a new way of addressing processes with the format
'pid:pidfd_inode'. When the new format is used, 'kill' assumes the user wishes
to use a pidfd to signal a process, and will therefore use pidfd_* routines
to complete the task if the provided inode matches the one from a previously
acquired pidfd.
