sysv-generator: fix coding-style
Fix weird coding-style:
- proper white-space
- no if (func() >= 0) bail-outs
- fix braces
- avoid 'r' for anything but errno
- init _cleanup_ variables unconditionally, even if not needed
kmod was fixed upstream to no longer return ENOSYS. Also see:

The kmod fix is marked for backport, so no reason to bump the kmod
version we depend on.

nspawn: Don't remount with fewer options
When we do a MS_BIND mount, it inherits the flags of its parent mount.
When we do a remount, it sets the flags to exactly what is specified.
If we are in a user namespace then these mount points have their flags
locked, so you can't reduce the protection.
As a consequence, the default setup of mount_all doesn't work with user
namespaces. However if we ensure we add the mount flags of the parent
mount when remounting, then we aren't removing mount options, so we
aren't trying to unlock an option that we aren't allowed to.

logind: fix delayed execution regression
Commit c0f32805 ("logind: use sd_event timer source for inhibitor
logic") reworked the main loop logic of logind so that it uses a
real timeout callback handler to execute delayed functions.
What the old code did, however, was to call those functions on
every iteration in the main loop, not only when the timeout
expired.
Restore that behavior by bringing back manager_dispatch_delayed(),
and call it from manager_run(). The internal event source callback
manager_inhibit_timeout_handler() was turned into a wrapper of
manager_dispatch_delayed() now.

The kernel bonding layer allows passing an array of ARP IP targets as
bond-configuration. Due to the weird implementation of arrays in netlink
(which we haven't figure out a generic way to support, yet), we usually
hard-code the supported array-sizes. However, this should not be exported
from sd-netlink.
Instead, make sure the caller just uses it's current hack of enumerating
the types, and the sd-netlink core will have it's own list of supported
array-sizes (to be removed in future extensions, btw!). If either does not
match, we will just return a normal error.
Note that we provide 2 constants for ARP_IP_TARGETS_MAX now. However, both
have very different reasons:
- the constant in netdev-bond.c is used to warn the user that the given
number of targets might not be supported by the kernel (even though the
kernel might increase that number at _any_ time)
- the constant in sd-netlink is solely used due to us missing a proper
array implementation. Once that's supported in the type-system, it can
be removed without notice
Last but not least, this patch turns the log_error() into a log_warning().
Given that the previous condition was off-by-one, anyway, it never hit at
the right time. Thus, it was probably of no real use.

sd-netlink: don't treat NULL as root type-system
Explicitly export the root type-system to the type-system callers. This
avoids treating NULL as root, which for one really looks backwards (NULL
is usually a leaf, not root), and secondly prevents us from properly
debugging calling into non-nested types.
Also rename the root to "type_system_root". Once we support more than
rtnl, well will have to revisit that, anyway.

sd-netlink: don't treat type_system->count==0 as invalid
Empty type-systems are just fine. Avoid the nasty hack in

sd-netlink: make sure the root-level type is nested
In sd-netlink-message, we always guarantee that the currently selected
type-system is non-NULL. Otherwise, we would be unable to parse any types
in the current container level. Hence, this assertion must be true:
message->container_type_system[m->n_containers] != NULL
During message_new() we currently do not verify that this assertion is
true. Instead, we blindly access nl_type->type_system and use it (which
might be NULL for basic types and unions). Fix this, by explicitly
checking that the root-level type is nested.
Note that this is *not* a strict requirement of netlink, but it's a strict
requirement for all message types we currently support. Furthermore, all
the callers of message_new() already verify that only supported types are
passed, therefore, this is a pure cosmetic check. However, it might be
needed on the future, so make sure we don't trap into this once we change
the type-system.

nasty hack to treat empty type-systems as invalid. This might need some

sd-netlink: make NLType internal
If we extend NLType to support arrays and further extended types, we

of netlink-types.c, extend this to also avoid accessing any other fields.
Provide accessor functions for nl_type->type and nl_type->size and then
move NLType away from the type-system header.
With this in place, follow-up patches can safely turn "type_system" and
"type_system_union" into a real "union { }", and then add another type for
arrays.
Make sure we never access type->type_system or type->type_system_union
directly. This is an implementation detail of the type-system and we
should always use the accessors. Right now, they only exist for 2-level
accesses (type-system to type-system). This patch introduces the 1-level
accessors (type to type-system) and makes use of it.
This patch makes sure the proper assertions are in place, so we never
accidentally access sub-type-systems for non-nested/union types.
Note that this places hard-asserts on the accessors. This should be fine,
as we expect callers to only access sub type-systems if they *know*
they're dealing with nested types.
