Pretty much the only case where we do NOT want to daemonize
a container start is lxc-start.  So make c->daemonize true
by default, and have lxc-start set it to false.

If there are existing API users who rely on daemonize by
default, then they will be broken by this.  It seems we should
do this before beta1 if we're going to do it.

This makes the ubuntu and ubuntu-cloud templates automatically aware of apt
proxy settings when the LXC host has "squid-deb-proxy-client" installed. This
makes installations *much* faster when a suitable squid-deb-proxy is
found on the network (or installed on the host).

This adds a new --force-cache parameter which will force use of the
cache even for expired images.

An expired image is now only flushed from the cache once a new one is
successfuly downloaded (to avoid destroying the local cache when the
host doesn't have internet connectivity).

The ID of the build in cache is also tracked so that we don't
re-download something we already have (should only happen if we don't
have a new build published by the time the previous one expires).

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.

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.

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.

If /proc/self/ns does not exist, then preserve_ns was failing to
initialize the saved_ns[i] to -1.  This caused attach_ns() to try
and attach, and of course fail.

Initialize the saved ns values before returning an error.

The return values of preserve_ns and attach_ns were also being
ignored.  Honor them.
