`networkctl lldp` and `networkctl status INTERFACE` now use varlink
call to the networkd to query LLDP neighbors.
Then, this allows to dump LLDP neighbors in JSON format.

Add functions serializing LLDP neighbors to JSON (JsonVariant).
The entry contains a chassis id, system name and port id of the remote
neighbor. Also it possibly contains an integer coding the enabled system
capabilities and port description.
Partially reverts commit b0d3095fd6.
While it is generally worthwhile for systemd to drop split-usr support,
these options are NOT about split-usr support. The universal location of
POSIX sh is always /bin/sh. Bash is pretty reasonably standardized there
too.
This happens irrespective of /bin being a symlink to /usr/bin.
Ramifications of this change include things like:
- portably running shell scripts that might run very nearly anywhere
- /etc/shells support
For standardization and compatibility reasons, these commands with these
paths need to be consistently found on any system, and thus distros make
sure this works, although even on split-usr systems /usr/bin/bash may be
a symlink to /bin/bash.
Embedding the *access path* of bash as /usr/bin/bash in systemd, for
example in libnss_systemd.so, means that login shells must agree with
systemd on how they invoke the shell. End result: users fail to login
because of access violations.
This cannot be fixed by "fixing PAM" because PAM does not follow
symlinks by design: one example is that it needs to treat rbash as
different from bash.

Tighten our VM check: whether we run in a VM is not enough to do
AF_VSOCK. We also need to check if we are run in a container, because if
we run in a container inside a VM then we should *not* do the AF_VSOCK
stuff, but leave the port free for the VM itself.
As discussed here:

This makes it easier for people packaging kernel-install plugins
to get the path right.
E.g. https://src.fedoraproject.org/rpms/python-virt-firmware/pull-request/3
fixes an issue where %{_libdir}/kernel/install.d was used,
which gives incorrect results on 64-bit architectures.
%_kernel_install_dir will make this even easier.
It appears the build-api effort at
https://github.com/cgwalters/build-api hasn't really caught on.
systemd appears one of the very few projects actually supporting it.
It does confuse certain tools though. E.g. debhelper by finding a
configure script wrongly assumes this is an autoconf project and thus
needs to be told explicitly that this is in fact a Meson project [1].
Given that Meson is an established build system by now, it appears ok to
drop this compat layer, which will never be fully complete anyway.

- avoid stripping debug symbols and creating dbgsym packages
- avoid LTO, slows down build a lot
- avoid compressing packages, they are thrown out immediately after use
- avoid building udeb packages, not needed
let's make userspace verity signature checking optional. This adds a
dissection flag to enable the logic and patches through all our users to
enable it by default, thus effectively not changing anything from the
status quo ante. However, know we have a knob to turn this off in
certain scenarios.
The glibc API is behind the wrapper is called "secure_getenv()", hence
our wrapper really should keep the order too, otherwise things are just
too confusing.
Most of our kernel cmdline options use underscores as word separators in
kernel cmdline options, but there were some exceptions. Let's fix those,
and also use underscores.
Since our /proc/cmdline parsers don't distinguish between the two
characters anyway this should not break anything, but makes sure our own
codebase (and in particular docs and log messages) are internally
consistent.
