75cd513ef8 resolved: avoid possible dereference of null pointer
In dns_scope_make_reply_packet the structs q, answer, and soa can be
null. We should check for null before reading their fields.

23f25b1496 switch-root: umount the old root correctly
The unmount occurs after the pivot_root, so the path used to unmount
should take into account the new root directory. This will allow the
umount to actually succeed.

4212a3375e nspawn: fix truncation of machine names in interface names
Based on patch by Michael Marineau <michael.marineau@coreos.com>:

When deriving the network interface name from machine name strncpy was
not properly null terminating the string and the maximum string size as
returned by strlen() is actually IFNAMSIZ-1, not IFNAMSIZ.

9a6f36c08f bootchart: ask for --rel when failed to initialize graph start time
We always read system uptime before log start time. So the uptime
should be always smaller number, except it includes system suspend
time. It seems better to ask for --rel and exit() than try to be
smart and try to recovery from this situation or generate huge
messy graphs.

c358d728e7 bootchart: don't parse /proc/uptime, use CLOCK_BOOTTIME
* systemd-bootchart always parses /proc/uptime, although the
  information is unnecessary when --rel specified

* use /proc/uptime is overkill, since Linux 2.6.39 we have
  clock_gettime(CLOCK_BOOTTIME, ...). The backend on kernel side is
  get_monotonic_boottime() in both cases.

* main() uses "if (graph_start <= 0.0)" to detect that /proc is
  available.

  This is fragile solution as graph_start is always smaller than zero
  on all systems after suspend/resume (e.g. laptops), because in this
  case the system uptime includes suspend time and uptime is always
  greater number than monotonic time. For example right now difference
  between uptime and monotonic time is 37 hours on my laptop.

  Note that main() calls log_uptime() (to parse /proc/uptime) for each
  sample when it believes that /proc is not available. So on my laptop
  systemd-boochars spends all live with /proc/uptime parsing +
  nanosleep(), try

    strace  /usr/lib/systemd/systemd-bootchart

  to see the never ending loop.

  This patch uses access("/proc/vmstat", F_OK) to detect procfs.

dced15575f util.h: include missing.h, for struct file_handle
This breaks udev-builtin-btrfs.c, which reinvents some of missing.h,
so use missing.h there too.

[zj: removed #include "config.h" and wrapped #include <linux/btrfs.h>
     in ifdef HAVE_LINUX_BTRFS_H as discussed on the mailing list.]

4e945a6f79 resolved: beef up DNS server configuration logic
We now maintain two lists of DNS servers: system servers and fallback
servers.

system servers are used in combination with any per-link servers.

fallback servers are only used if there are no system servers or
per-link servers configured.

The system server list is supposed to be populated from a foreign tool's
/etc/resolv.conf (not implemented yet).

Also adds a configuration switch for LLMNR, that allows configuring
whether LLMNR shall be used simply for resolving or also for responding.

Make sure we format UTF-8 labels as IDNA when writing them to DNS

When comparing or processing labels always consider native UTF-8 and
IDNA formats equivalent.
