inspawn: switch from SOCK_DGRAM to SOCK_SEQPACKET for internal socketpairs

SOCK_DGRAM and SOCK_SEQPACKET have very similar semantics when used with
socketpair(). However, SOCK_SEQPACKET has the advantage of knowing a
hangup concept, since it is inherently connection-oriented.

Since we use socket pairs to communicate between the nspawn main process
and the nspawn child process, where the child might die abnormally it's
interesting to us to learn about this via hangups if the child side of
the pair is closed. Hence, let's switch to SOCK_SEQPACKET for these
internal communication sockets.

(ordered alphabetically for better visibility)

This is grossly incorrect. The spec says that we're allowed to return
non-directed children, however, it does not allow us to return data
recursively in multiple parents. If we return "org", then we must not
return anything else that starts with "org/".

It is unclear, whether we can include child-nodes as a tree. Moreover, it
is usually not what the caller wants. Hence, this patch changes sd-bus to
never return introspection data recursively. Instead, only a single
child-layer is returned.

This patch relies on enumerators to never return hierarchies. If someone
registers an enumerator via sd_bus_add_enumerator, they better register
sub-enumerators if they support *TRUE* hierarchies. Each enumerator is
treated as a single layer and not filtered.
Enumerators are still allowed to return nested data. However, that data
is still required to be a single hierarchy. For instance, returning
"/org/foo" and "/com/bar" is fine, but including "/com" or "/org" in that
dataset is not.
This should be the default for enumerators and I see no reason to filter
in sd-bus. Moreover, filtering that data-set would require to sort the
strv by path and then do prefix-filtering. This is O(n log n), which
would be fine, but still better to avoid.

systemd-internal headers must not rely on include order. That means, they
either must contain forward-declarations of used types/functions, or they
must include all dependencies on their own. Therefore, there is no reason
to mandate an include order on the call-side.

However, global includes should always be ordered first. We don't want
local definitions to leak into global includes, possible changing their
behavior. Apparently, namespacing is a complex problem that people are
incapable of implementing properly..

Apart from "global before local", there is no reason to mandate a random
include order (which we happen to do right now). Instead, mandate
alphabetical ordering. The current rules do not have any benefit at all.

sd-bus: derive uid from cgroup if possible

Whenever we run in a user context, sd_bus_{default_user,open_user}() and
friends should always connect to the user-bus of the current context,
instead of deriving the uid from getuid(). This allows us running
programs via sudo/su, without the nasty side-effect of accidentally
connecting to the root user-bus.

This patch enforces the idea of making su/sudo *not* opening sessions by
default. That is, all they do is raising privileges, but keeping
everything set as before. You can still use su/sudo to open real sessions
by requesting a login-session (or loading pam_systemd otherwise).
However, in this case XDG_RUNTIME_DIR= will not be set (as usual in these
cases), hence, you will not be able to connect to *any* user-bus.

Long story short: With this patch applied, both:
        - ./busctl --user
        - sudo ./busctl --user
..will successfully connect to the user-bus of the local user.

bus-proxy: increase NOFILE limit

The bus-proxy manages the kdbus connections of all users on the system
(regarding the system bus), hence, it needs an elevated NOFILE.
Otherwise, a single user can trigger ENFILE by opening NOFILE connections
to the bus-proxy.

Note that the bus-proxy still does per-user accounting, indirectly via
the proxy/fake API of kdbus. Hence, the effective per-user limit is not
raised by this. However, we now prevent one user from consuming the whole
FD limit of the shared proxy.

Also note that there is no *perfect* way to set this. The proxy is a
shared object, so it needs a larger NOFILE limit than the highest limit
of all users. This limit can be changed dynamically, though. Hence, we
cannot protect against it. However, a raised NOFILE limit is a privilege,
so we just treat it as such and basically allow these privileged users to
be able to consume more resources than normal users (and, maybe, cause
some limits to be exceeded by this).

Right now, kdbus hard-codes 1024 max connections per user on each bus.
However, we *must not* rely on this. This limits could be easily dropped
entirely, as the NOFILE limit is a suitable limit on its on.
