units: symlink well-known Varlink services into /run/varlink/registry/

So far we didn't provide any concept to enumerate local Varlink
services. Let's change that.

Let's define very light-weight scheme for this: provide a well-known dir
/run/varlink/registry/ where services that implement public interfaces
can link their sockets into. When enumerating services it's thus
sufficient to enumerate inodes in that directory.

The usecase for this is twofold:

1. It's simply very useful to be able to see which public services are
   bound on the local system, for debugging/admin/development purposes.

2. At Amutable we'd like to optionally provide a HTTP-to-Varlink bridge
   on individual nodes, that allows remote peers (after authentication)
   to access local Varlink services. For that it's essential we know the
   list of services and their entrypoints to expose, it would be
   security-wise highly problematic for clients to provide AF_UNIX
   entrypoint paths when connecting. hence: let's instead just have a
   dir with the public stuff, and let's ensure the HTTP-to-Varlink
   bridge simply exposes that stuff, and nothing else.

Non-public interfaces (such as the oomd interfaces between PID 1 and
oomd), and interfaces with multiple implementors (such as the resolved
hook interface, or the metrics collection stuff) should not be linked
in.

This is inspired by the Varlink.org "registry" concept, briefly
explained here:

https://varlink.org/FAQ#how-do-i-find-the-service-which-implements-a-local-interface

Note however that the described Varlink interface is not actually
implemented here, the directory is introduced however in a fashion that
conceptually matches the registry defined there, and would allow us to
implement the registry interface on top of it. (One of the reason the
registry Varlink API is not implemented right now is that the URI format
it relies on is entirely unspecified in the Varlink docs right now. Some
research needs to be done to extract what's implemented in the reference
implementation and to determine how it maps to the Varlink entrypoint
address format systemd's own tooling currently uses)

This primarily installs the symlinks via Symlinks= in unit files and via
a new tmpfiles.d/ drop-in. But since we touch all .socket units relating
to Varlink this also sets the FileDescriptorName= to varlink for each,
just to minimize diffrences and make things work more alike (the
services in questin don't care about the name, so this doesn't change).
In one case we replace a pair of separate sockets for two closely
related varlink services by a socket and a symlink, so that we can
safely use Symlinks= to also install the registry symlinks.

safely lifecycle all operation parameters for each subequent call.

the fact that we explicitly support autofs for the ESP/XBOOTLDR itself,

nsresourced: Ensure that all user namespaces are cleaned-up

The code here assumes that free_user_ns() is called for every single
user namespace. That however has never been the case and the logic for
free_user_ns() is a bit more involved.

A nested user namespace pins its parent user namespace. IOW, the
lifetime of the parent user namespaces is at least as long as the child
user namespaces.

If a parent user namespace becomes unused (no namespace file descriptors
or task using it anymore) then it will stick around and its lifetime
still bound to the child user namespace.

free_user_ns() takes advantage of that behavior. If a child user
namespace is freed and its parent user namespace is already unused then
then free_user_ns() will free both the child and the parent user
namespace. This means a single free_user_ns() frees two user namespaces.
Hence, the bpf program never sees the parent user namespace being freed.

We can fix this by piggy-backing on another function that is called for
every single user namespace being freed. This requires CONFIG_SYSCTL but
systemd doesn't work without that anyway.

The return type needs to change to a scalar type as required by libbpf.

Long-term what we need is appropriate LSM infrastructure for this
including hooks that get called on namespace destruction.

Thanks to Daan DeMeyer for figuring out that the cast is needed.
