45bc27b621 journalctl: rename boot_id_t to BootId
So far we tried to reserve the _t suffix to types we use like a value in
contrast to types we use as objects, hence let's do this in journalctl
too.

909dea0c7c journalctl: only have a single exit path from main()
That way we can be sure we execute the destructors properly, and can be
valgrind-clean.

596a23293d journalctl: Improve boot ID lookup
This method should greatly improve offset based lookup, by simply jumping
from one boot to the next boot. It starts at the journal head to get the
a boot ID, makes a _BOOT_ID match and then comes from the opposite
journal direction (tail) to get to the end that boot. After flushing the matches
and advancing the journal from that exact position, we arrive at the start
of next boot. Rinse and repeat.

This is faster than the old method of aggregating the full boot listing just
so we can jump to a specific boot, which can be a real pain on big journals
just for a mere "-b -1" case.

As an additional benefit --list-boots should improve slightly too, because
it does less seeking.

Note that there can be a change in boot order with this lookup method
because it will use the order of boots in the journal, not the realtime stamp
stored in them. That's arguably better, though.
Another deficiency is that it will get confused with boots interleaving in the
journal, therefore, it will refuse operation in --merge, --file and --directory mode.

6b7d2e9ea4 nspawn: close extra fds before execing init
When systemd-nspawn gets exec*()ed, it inherits the followings file
descriptors:
- 0, 1, 2: stdin, stdout, stderr
- SD_LISTEN_FDS_START, ... SD_LISTEN_FDS_START+LISTEN_FDS: file
  descriptors passed by the system manager (useful for socket
  activation). They are passed to the child process (process leader).
- extra lock fd: rkt passes a locked directory as an extra fd, so the
  directory remains locked as long as the container is alive.

systemd-nspawn used to close all open fds except 0, 1, 2 and the
SD_LISTEN_FDS_START..SD_LISTEN_FDS_START+LISTEN_FDS. This patch delays
the close just before the exec so the nspawn process (parent) keeps the
extra fds open.

This patch supersedes the previous attempt ("cloexec extraneous fds"):

ee818b89f4 core: Private*/Protect* options with RootDirectory
When a service is chrooted with the option RootDirectory=/opt/..., then

3519d230c8 fstab-generator: add x-systemd.requires and x-systemd.requires-mounts-for
Currently we have no way how to specify dependencies between fstab
entries (or another units) in the /etc/fstab. It means that users are
forced to bypass fstab and write .mount units manually.

The patch introduces new systemd fstab options:

x-systemd.requires=<PATH>

 - to specify dependence an another mount (PATH is translated to unit name)

x-systemd.requires=<UNIT>

 - to specify dependence on arbitrary UNIT

x-systemd.requires-mounts-for=<PATH ...>

 - to specify dependence on another paths, implemented by
   RequiresMountsFor=. The option may be specified more than once.

For example two bind mounts where B depends on A:

 /mnt/test/A    /mnt/test/A     none    bind,defaults
 /mnt/test/A    /mnt/test/B     none    bind,x-systemd.requires=/mnt/test/A

More complex example with overlay FS where one mount point depends on
"low" and "upper" directories:

 /dev/sdc1   /mnt/low    ext4     defaults
 /dev/sdc2   /mnt/high   ext4     defaults
 overlay     /mnt/merged overlay  lowerdir=/mnt/low,upperdir=/mnt/high/data,workdir=/mnt/high/work,x-systemd.requires-mounts-for=/mnt/low,x-systemd.requires-mounts-for=mnt/high

fb869ca1d2 zsh-completion: actually complete template names for subcommands enable, reenable and disable.
compadd's -a option treats non-option arguments as arrays. So
$(_systemctl_get_template_names) expands to some words that aren't
legal array names. Even if there were, they would be empty; thus adding
nothing.

deduplicated a few functions too.

7693146dee socket-util: socket_address_parse() should not log errors on its own
Given that socket_address_parse() is mostly a "library" call it
shouldn't log on its own, but leave that to its caller.

This patch removes logging from the call in case IPv6 is not available
but and IPv6 address shall be parsed. Instead a new call
socket_address_parse_and_warn() is introduced which first invokes
socket_address_parse() and then logs if necessary.

This should fix "make check" on ipv6-less kernels:
