utmpx.h is specified in POSIX but utmpxname is not so we check for
utmpxname in configure script.
This fixes the following compile error with musl libc:
lxcutmp.c: In function 'utmp_get_runlevel':
lxcutmp.c:249:2: error: implicit declaration of function 'utmpxname' [-Werror=implicit-function-declaration]

lxc-ps and lxc-netstat have an unfortunate tendency to break every so
often, produce mostly unreadable output and should be replaced by a
lxc-attach call in 99% of the cases.
In an effort to cleanup the lxc-* namespace, I think those two should
go, so this patch gets rid of them as well as any reference to them in
our documentation.
I also think that lxc-version should disappear as it's only a one line
shell script printing the version string, so having a whole command just
for that seems to be a bit of a waste.
Instead, this patch introduces a new --version common option which all
binaries will automatically inherit and that'll print LXC_VERSION on
stdout and exit 0.

This adds a basic bash auto-completion profile.
It supports 3 things at this time:
- Auto-complete of container name (-n or -o)
- Auto-complete of template name (-t)
- Auto-complete of state names (-s)
It's configured in a way to be as little disruptive as possible, any
argument that's not explicitly handled by the profile will fallack to
bash's default completion.

This updates the Fedora and CentOS templates to utilize a common
included config. This is largely based on the changes in the Oracle
template with some exceptions.
Dropping of setpcap (present in the Oracle template) is commented out in
the Fedora template. It seems to cause problems, such as large login
delays with Fedora 20 containers (but not Fedora 19 - strange).
The Fedora template is further modified to disable systemd-journald.service
as it is unnecessary in a container and causes serious problems when
running in a Fedora 20 container.
The Fedora template is also updated to default to Fedora 20 when running
on a non-Fedora host.

Mike

This adds the 3 upstart jobs that we've had in Ubuntu for a while:
- lxc.conf: Main upstart job, triggers lxc-net.conf based on config
- lxc-instance.conf: Triggered by lxc.conf for each auto-started container
- lxc-net.conf: Triggered by lxc.conf, sets up lxcbr0, NAT, mangling, ...
In addition, there are two extra config files in /etc/default:
- lxc: Allows setting some values like http proxying, disabling autostart, ...
- lxc-net: Network configuration for the lxcbr0 bridge
This change also disables the sysv script for all distros but Oracle as
the current script won't work on either Ubuntu nor Debian and I suspect
quite a few more distros, so it's not nearly as distro-agnostic as we
thought.
For Debian, only install the upstart jobs and systemd unit.
For Ubuntu, only install the upstart jobs.
This change also moves all the init related stuff to config/init/

This patch splits out most of the cgroupfs-specific code, so that
cgroup-manager versions can be plugged in. The case I did
not handle is cgroup_enter at lxc_attach. I'm hoping that case can
be greatly simplified, but will worry about it after fleshing out the
cgroup manager handlers.
This also simplify the freezer functions.
This seems to not regress my common tests when running without
cgmanager, but I'd like to do a bit more testing before pushing.
However I was hoping to get some more eyes on this so am sending it
out now.

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.

This change updates the way init scripts get installed so that more
than one init system can be supported. Instead of installing the
systemd service file from the spec file, it should be installed at
make install time, so that someone compiling from source also gets
the unit file installed.
Update the plamo template to use a lock file not named just
/var/lock/subsys/lxc since the presence of that file is used by
sysv init rc file to know if it should run the K01lxc script. This
also makes it consistent with the other templates which use
/var/lock/subsys/lxc-$template-name.

This introduces a new lxc-autostart binary (and associated manpage)
which will let you start/shutdown/kill/restart any container that's
marked as lxc.start.auto=1. It respects the lxc.start.delay value,
sorts by lxc.start.order and filters by lxc.group.
By default it'll affect all containers that DO NOT have lxc.group
set. If -g is specified, ONLY containers in those group will be
affected. To have a command applied to all containers, the -a
argument can be used.
A -L flag is also offered for distributions wishing to start the
containers themselves while still using LXC's calculated order and
wait delays. Instead of performing the action, it'll print the container
name and (if relevant for the action) the wait time.

This introduces a new /usr/share/lxc/config directory containing common
configuration snippets.
The two Ubuntu templates are then simplified to just include the
relevant entries avoiding a whole lot of hardcoded cgroup, capabilities
and mount points configuration.
An extra comment is also added at the top of all generated configuration
files telling the user to look at lxc.conf(5) for more information.

This adds an lxc-centos template for crreating CentOS 5+ templates. It
does NOT create CentOS 4 or earlier containers as these are way past
end of life and no longer supported. It is based on the work of
Fajar A. Nugraha <github@fajar.net> who modified an earlier Fedora
template. His work has been brought LARGELY into congruence with
the current Fedora template. It still lacks the distro agnostic
bootstrap and systemd code from the Fedora template but those should
only be relevant with CentOS 7 when that can of worms pops open
sometime next year or so.
