download: Initial template

This adds a new template called "download". It's a fairly simple
template with a minimal set of dependency which will grab any pre-built
image available on https://images.linuxcontainers.org
Note that the serverside is still work in progress (missing SSL support).

Access is done over https by default with a warning being emitted if
fallback to http was required (may be needed for testing, when behind
proxy and with private servers). All index files and tarballs are
gpg-signed with the default pubkeyid contained in the template itself.

The main benefit of this template is to be entirely
distribution-agnostic, any template that can be integrated with the
server build infrastructure will then work on any LXC machine when using
the download template. This template is also compatible with user
namespaces and will hopefully help widden the number of distros that may
work in unprivileged LXC.

This commit also bundles a small change to the template configs to have
the ubuntu template (used by the download template) to work with
unprivileged LXC.

cgroup: recursively delete cgroups when asked

Currently when a container is shut down, lxc walks the set of all
cgroup paths it created, in reverse order, and tries to remove them.
This doesn't suffice if the container has also created new cgroups.

It'd be impolite to recursively remove all the cgroup paths we created,
since this can include '/lxc' and thereunder all other containers
started since.

This patch changes container shutdown to only delete the container's own
path, but do so recursively.  Note that if we fail during startup,
the container won't have created any cgroup paths so it the old
way works fine.

ensure all config items are duplicated on clone/write_config

Since previously I had found a config item that wasn't being propagated
by lxc-clone, I went through all the config items and made sure that:
 a) Each item is documented in lxc.conf
 b) Each item is written out by write_config

The only one that isn't is lxc.include, which by its nature only pulls
in other config item types.

usernsexec: don't fail if we can't open pty

It's nice if we can do it, but not required.  Exiting on this
failure causes lxc-create started by root as a less-privileged
userid to fail.

introduce lxc-unpriv test

It simply creates a test user and tries to create and start
a container as that user.  Tries to lxc-attach to that
container to test network connectivity.

This change introduce mac address templating.

By setting lxc.network.hwaddr to something like fe:xx:xx:xx:xx:xx each
"x" will be replaced by a random value.  If less significant bit of
first byte is "templated", it will be set to 0.

This change introduce also a common randinit() function that could be
used to initialize random generator.

cgroup: move all some functions into cgroup.h

Some functions which wanted to know about cgroup paths were located
in other files.  Move them into cgroup.c, so that all knowledge of
the cgroup backend can be colocated.
