Lennart Poettering 5fb13eb51b tmpfiles: introduce "q" and "Q" for creating quota-enabled btrfs subvolumes 
This allows us to set up the quota group hierarchy in a reasonable way
on btrfs file systems.

Lennart Poettering 5bcd08db28 btrfs: beef-up btrfs support with a limited understanding of quota 
With this change we understand more than just leaf quota groups for
btrfs file systems. Specifically:

- When we create a subvolume we can now optionally add the new subvolume
  to all qgroups its parent subvolume was member of too. Alternatively
  it is also possible to insert an intermediary quota group between the
  parent's qgroups and the subvolume's leaf qgroup, which is useful for
  a concept of "subtree" qgroups, that contain a subvolume and all its
  children.

- The remove logic for subvolumes has been updated to optionally remove
  any leaf qgroups or "subtree" qgroups, following the logic above.

- The snapshot logic for subvolumes has been updated to replicate the
  original qgroup setup of the source, if it follows the "subtree"
  design described above. It will not cover qgroup setups that introduce
  arbitrary qgroups, especially those orthogonal to the subvolume
  hierarchy.

This also tries to be more graceful when setting up /var/lib/machines as
btrfs. For example, if mkfs.btrfs is missing we don't even try to set it
up as loopback device.

Add support for this back.

Tom Gundersen 84de38c569 networkd: manager/link - only serialize once per event-loop iteration 
Every time the state is written out we may trigger third-party apps, so
let's be a bit more careful about writing this out unnecessarily.

Tom Gundersen adda1ed94a networkd: address - distinguish between addresses added by us and by others 
We only keep the addresses that we added ourselves in link->addresses, and
introduce a new set link->addresses_foreign to keep addresses of unknown
origin.

Only functional change is that "foreign" addresses no longer prevent a link
from entering "configured" state.

Iago López Galeiras d167824896 nspawn: skip /sys-as-tmpfs if we don't use private-network 
Since v3.11/7dc5dbc ("sysfs: Restrict mounting sysfs"), the kernel
doesn't allow mounting sysfs if you don't have CAP_SYS_ADMIN rights over
the network namespace.

So the mounting /sys as a tmpfs code introduced in
d8fc6a000f doesn't work with user
namespaces if we don't use private-net. The reason is that we mount
sysfs inside the container and we're in the network namespace of the host
but we don't have CAP_SYS_ADMIN over that namespace.

To fix that, we mount /sys as a sysfs (instead of tmpfs) if we don't use
private network and ignore the /sys-as-a-tmpfs code if we find that /sys
is already mounted as sysfs.

Fixes #1555
