Using $(date) for LXC_GENERATE_DATE has various flaws:
* formating depends on the locale of the system we execute configure on
* the output is not really a date but more a timestamp
Let's use $(date --utc '+%Y-%m-%d') instead.
While at it, also support SOURCE_DATE_EPOCH [1] to make the build
reproducible

* This script sets /dev/.lxc which is needed for autodev containers.
* Previously was only executed with systemd. Execute it also with
the other init systems (sysvinit and upstart)

New template script is more readable and robust, uses cache and external
LXC config file as other templates.

- lxc-clone and lxc-start-ephemeral are marked deprecated. We add a
--enable-deprecated flag to configure.ac allowing us to enable these
deprecated executables
- update tests to use lxc-copy instead of lxc-clone

lxc-ls nowadays is a C binary so there's no need to keep the python and
shell versions around anymore, remove them from the branch and cleanup
documentation and Makefiles.

Linux for SPARC is a free community Linux distribution for SPARC hosted by Oracle. See : https://oss.oracle.com/projects/linux-sparc
While the distribution is based on Oracle Linux it does have some differences and since it's not actually Oracle Linux I decided to add a separate template rather than having the Oracle Linux template also support Linux for SPARC.
This patch adds the lxc-template for Linux for SPARC and it also adds Linux for SPARC in the configure.ac as a distribution target to build.

Newer kernels have added a new restriction: if /proc or /sys on the
host has files or non-empty directories which are over-mounted, and
there is no /proc which fully visible, then it assumes there is a
"security" reason for this. It prevents anyone in a non-initial user
namespace from creating a new proc or sysfs mount.
To work around this, this patch adds a new 'nesting.conf' which can be
lxc.include'd from a container configuration file. It adds a
non-overmounted mount of /proc and /sys under /dev/.lxc, so that the
kernel can see that we're not trying to *hide* things like /proc/uptime.
and /sys/devices/virtual/net. If the host adds this to the config file
for container w1, then container w1 will support unprivileged child
containers.
The nesting.conf file also sets the apparmor profile to the with-nesting
variant, since that is required anyway. This actually means that
supporting nesting isn't really more work than it used to be, just
different. Instead of adding
lxc.aa_profile = lxc-container-default-with-nesting
you now just need to
lxc.include = /usr/share/lxc/config/nesting.conf
(Look, fewer characters :)
Finally, in order to maintain the current apparmor protections on
proc and sys, we make /dev/.lxc/{proc,sys} non-read/writeable.
We don't need to be able to use them, we're just showing the
kernel what's what.

On restore, we pass criu a script to manage the network interfaces (i.e. the
full path to lxc-restore-net), which we previously installed into
/var/lib/<tuple>/lxc. However, this is also the directory that is the default
for use in mounting the rootfs locally before pivot_root()ing. So, we mounted
the rootfs and then happliy called criu, pointing it to this directory which
didn't have lxc-restore-net any more, it just had the container's rootfs.
Instead, we should put lxc-restore-net somewhere else, so that criu can still
see it after the rootfs is mounted.
