a19222e1d3 nspawn: don't try to extract quotes from option string, glibc doesn't do that either

5e5bfa6e1c nspawn: add (no)rbind option to --bind and --bind-ro
--bind and --bind-ro perform the bind mount
non-recursively. It is sometimes (often?) desirable
to do a recursive mount. This patch adds an optional
set of bind mount options in the form of:
	--bind=src-path:dst-path:options
options are comma separated and currently only
"rbind" and "norbind" are allowed.
Default value is "rbind".

83cedf7ae2 sd-dhcp-server: improve predictability of leases
Rather than having all clients attempt to get the same leases (starting at the
beginning of the pool), make each client star at a random offset into the pool
determined by their client id. This greatly increases the chances of a given
client receiving the same IP address even though both the client and server
have lost any lease information (and distinct server instances handing out
the same leases).

45d7a8bb6c cgtop: major modernizations
In preparation of the unified cgroup support, let's clean up cgtop:

a) rework time code to be based on "nsec_t" rather than "struct timespec"

b) Introduce long option --order= for selecting ordering

c) count number of processes only in the main hierarchy, don't bother
   with the controller hierarchies. We don't allow orthogonal
   hierarchies in systemd anymore, hence there's no point to check the
   other hierarchies.

d) Deal with non-monotonic cpuacct values (see #749)

e) When sorting groups, don't do prefix compare when ordering by number
   of tasks, since this is not accumulative for all children.

f) Actually make --cpu without parameter work

g) Don't output control characters when we get them as input.

Fixes #749.

21b735e798 core: add unit_dbus_interface_from_type() to unit-name.h
Let's add a way to get the type-specific D-Bus interface of a unit from
either its type or name to src/basic/unit-name.[ch]. That way we can
share it with the client side, where it is useful in tools like cgls or
machinectl.

Also ports over machinectl to make use of this.

154429127c sd-bus: do not connect to dbus-1 socket when kdbus is available
We should not fall back to dbus-1 and connect to the proxy when kdbus
returns an error that indicates that kdbus is running but just does not
accept new connections because of quota limits or something similar.

Based on a patch by Kay.

057171efc1 Revert "sd-bus: do not connect to dbus-1 socket when kdbus is available"
This reverts commit d4d00020d6. The idea of
the commit is broken and needs to be reworked. We really cannot reduce
the bus-addresses to a single address. We always will have systemd with
native clients and legacy clients at the same time, so we also need both
addresses at the same time.

8faae625dc selinux: drop mac_selinux_unit_access_check_strv()
It is not acceptable to load unit files during enable/disable operations
just to figure out the selinux labels. systemd implements lazy loading
for units, so the selinux hooks need to follow it.

This drops the mac_selinux_unit_access_check_strv() helper which
implements a non-acceptable policy check. If anyone cares for that
functionality, you really should pass a callback+userdata to the helpers
in src/shared/install.c which does policy checks on each touched file.

See #1050 on github for more.

0339cd7707 dhcp: clean up dhcp4 lease object
a) drop handling of obsolete or unused DHCP options time_offset,
   mtu_aging_timeout, policy filter, mdr, ttl, ip forwarding settings.
   Should this become useful one day we can readd support for this.

b) For subnet mask and broadcast it is not always clear whether 0 or
   255.255.255.255 might be valid, hence maintain a boolean indicating
   validity next to it.

c) serialize/deserialize broadcast address, lifetime, T1 and T2 together
   with the rest of the fields in dhcp_lease_save() and
   dhcp_lease_load().

d) consistently return ENODATA from getter functions for data that is
   missing in the lease.

e) add missing getter calls for broadcast, lifetime, T1, T2.

f) when decoding DHCP options, generate debug messages on parse
   failures, but try to proceed if possible.

g) Similar, when deserializing a lease in dhcp_lease_load(), make sure
   we deal nicely with unparsable fields, to provide upgrade compat.

h) fix some memory allocations
