- If version != NULL criu_version_ok() stores the detected criu version in
version. Allocates memory for version which must be freed by caller.
- If version == NULL criu_version_ok() will return true when the version
matches, false in all other cases.

First, we're doing this so long a there is any cgroup config item -
even if no devices ones. Then if devices is not available we fail.
This was leading to Rob E's mysterious startup failures.
Secondly, we're not even using this info. The user was removed
awhile back.

The regression was introduced by commit
3c39b0b7a2 which makes it possible to
create working stretch containers by forcinig `init` to be in the
included package list.
However, `init` didn't exit before jessie, so now for wheezy we
explicitly include `sysvinit`; sysvinit on wheezy is essential,
so it would already be included anyway.

Newer versions of Android (5.0+, aka API Level 21+) include mntent.h,
which declares setmntent and endmntent. This hits an edge
case with the preprocessor checks in lxcmntent.h because HAVE_SETMNTENT
and HAVE_ENDMNTENT are both defined (in Bionic's mntent.h), but conf.c
always includes lxcmntent.h on Bionic! As a result, we get compiler
warnings of implicit function declarations for setmntent endmntent.
This patch always includes setmntent/endmntent/hasmntopt function
declarations on Bionic, which gets rid of these warnings.

A while ago cgroup modes were introduced to CRIU, which slightly changed
the behavior w.r.t. cgroups under the hood. What we're really after is
criu's --full mode, i.e. even if a particular cgroup directory exists
(in particular /lxc/$container[-$number] will, since we create it), we
should restore perms on that cgroup.
Things worked just fine for actual properties (except "special" properties
as criu refers to them, which I've just sent a patch for) because liblxc
creates no subdirectories, just the TLD.

The profile already contains
mount options=(rw, make-slave) -> **,
Which allows going through all mountpoints with make-slave,
so it seems to make sense to also allow the directly
recursive variant with "make-rslave".

Bind-mounts aren't harmful in containers, so long as they're not used to
bypass MAC policies.
This change allows bind-mounting of any path which isn't a dangerous
filesystem that's otherwise blocked by apparmor.
This also allows switching paths {r}shared or {r}private.

init 1.34 is not "Essential" anymore, in order to make it not required
on minimal chroots, docker containers, etc. Because of that we now need
to manually include it on systems that are expected to boot.

If you specify an interpreter path with "-I" or "--interpreter-path",
the architecture of the debian container can differ from the one of
the host.
Before creating the container, binfmt must be configured on the host:
the script checks the name of the interpreter in /proc/sys/fs/binfmt_misc/
to know where to install it in the container.
To create a MIPS container on an x86_64 host:
$ cat /proc/sys/fs/binfmt_misc/qemu-mips
enabled
interpreter //qemu-mips
flags: OC
offset 0
magic 7f454c4601020100000000000000000000020008
mask ffffffffffffff00fffffffffffffffffffeffff
$ sudo lxc-create -n virtmips-stretch -t debian -- \
--arch=mips \
--interpreter-path=./mips-linux-user/qemu-mips \
--mirror=http://ftp.debian.org/debian \
--release=stretch

In many environments the preference is to configure containers with
apt mirrors that are SSL-secured.
When building containers using the download template this can't be
done unless an insecure mirror is first used to install the
apt-transport-https package, then the sources reconfigured to
use the https URL.
When building containers without using the download template this
can't be done unless the container creator specifically includes
this package in the package list at build time. It seems more
intuitive to me to have the package installed by default.
Commit 396f75abb3 added the package
to the minbase variant, but this variant is not used by the download
template build process. The build process instead specifies no
variant, so this patch moves the package from the packages_template
package list in the minbase variant to the global packages_template
package list, ensuring that this package is included in all Ubuntu
build images that use the lxc-ubuntu template.

lxc-start started to default to daemonize the container when starting
this conflicts with type=simple of the systemd unit
call lxc-start with -F and thus force execution in foreground
that way we can feed the log to journald properly and keep type=simple

setuptools is recommended by Python Packaging Guide
https://python-packaging-user-guide.readthedocs.io/en/latest/current/
It contains some useful extensions like 'develop' command. Also it
is required for building wheels AFAIK.
The only downside is an extra build-time dependency. setuptools are
packaged in both Debian and Ubuntu (python3-setuptools), as well as
other major distros, so it shouldn't be an issue, I think.
