Consolidate lucid, maverick, natty, and oneiric templates into one 'ubuntu'
template.

Add support for specifying architecture.

Add support for '--trim|-x' option, which removes services like the lucid
template used to.  This creates smaller, faster-booting containers, but they
will not be safe with certain upgrades, like mountall or udev.  When -x is
not specified for lucid or maverick container, then install lxcguest from
the ubuntu-virt ppa, since it does not exist in the official archives, and
the container is not safe to boot without lxcguest.

Add support for '--bindhome <user>' option, which will cause /home/<user>
to be bind-mounted into the container, and create the user with his
original password, shell, and group memberships in the container.

changelog:
  june 23:
    lxc-ubuntu template: set lxc.arch in config
    install lxcguest when NOT trimming the container
    lxc-ubuntu: always install lxcguest in postprocess

This way I can do

	lxc-create -t ubuntu -f /etc/lxc.conf -n u1 -- -x

and have -x passed to the template

Create an lxc-clone script to clone containers.  It should probably
be factored into helpers and then enhanced, in particular to convert
between LVM and non-LVM containers, create non-snapshot LVM clones,
support loopback devices, and, when stable enough, to use
overlayfs, btrfs, etc.

But this is a start.

When we accept a connection, we have to set the close-on-exec flag,
otherwise that won't be possible to reboot a container through a

'setns.h' is not an lxc interface.

Also, a side effect of this declaration of 'setns.h' in the lxc header
files is to be distributed in the lxc tarball. This breaks the
lxc-attach command because the file is not automatically generated at
compile time.

src/lxc/conf.c will explicitly mount it anyway.  Furthermore, the fstab
entry, which is getting processed first, did not specify -o newinstance.
This can cause the host's devpts entry mount options to change, as in
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/607636.

The default appender for logs is currently the file one: this
make macros from log.h unusable as long as lxc_log_init() hasn't
been called. This prevents errors from even being printed on
stderr in lxc_caps_init() for example.

Let's make stderr the default appender.

lxc_cgroup_path_get currently cache the cgroup mount point plus the
container name at the same time, making every call of the function
returning the same value.
It mean that actually every call to lxc_cgroup_get with a different
container name will in fact use the same container name as used for
the primary call.

I join a patch to fix that, still doing some caching, but only caching
the cgroup moint point this time. This patch actually work for me, as
I am using the liblxc for retrieving statistics about all running
containers, using lxc_cgroup_get to retrieve every interesting values.
