Add a container config option to mount and populate /dev in a container.
We might want to add options to specify a max size for /dev other than
the default 100k, and to specify other devices to create. And maybe
someone can think of a better name than autodev.
Changelog: Don't error out if we couldn't mknod a /dev/ttyN.
Changelog: Describe the option in lxc.conf manpage.

This introduces a new add_devices() call to the python API.
Parameters:
- path => Mandatory, path to a character or block device on the host
- destpath => Optional, alternative path inside the container
The function will allow the node in the container's devices cgroup and
then create the entry in the container.

lxc-ls is currently exiting with return code 1 when called with --help
or when called on a system without containers.
This behaviour isn't documented in the manpage and isn't terribly intuitive.
It's been the source of quite a few weird failures in scripts running with
set -e.
As a user calling --help is a voluntary action, lxc-ls should exit 0.
Also, as lxc-ls's goal is solely to list containers, showing an error and
exiting with return code 1 when there's no container seems counter-intuitive
and error-prone.

The package 'docbook-tools' [1] required to format Docbook 3.0 into man pages
has been obsoleted a long time ago and can no longer be downloaded from its
former homepage. Recent versions of that package -- now called 'docbook2X' --,
cannot deal with that old markup format anymore (and don't support the '-w all'
command line switch either). To remedy these issues, all SGML files have been
updated to Docbook 4.5 so that recent versions of docbook2man can process them.

Change 5fd8314f removed the README file explaining why the

Fedora 17 since this directory will not be created by make

This allows a distro to put the distro specific default network
configuration (for example bridge device, link type), or other lxc
configuration in the case that -f is not passed by the user to
lxc-create, in which case lxc-create will use the distro conf file as
the basis for the containers config.

Make the oracle template honor the lxc.network.type and
lxc.network.link configuration items if a "base" configuration file is
passed to lxc-create. If no configuration file is passed and the host
system is Oracle or Fedora, the template assumes a type of veth and
the default name created by libvirt.

Use the file command to see if the rpm database version needs to
be downgraded. Use the lsb_release command to determine the host
system, which is then used to set the commands needed to do the
conversion, and lets us move the rpm database to the correct location
if the host rpm doesn't put it where the guest expects it to be.

This is a new template to create containers based on Oracle Linux. A version
such as 5.8, 6.3, or 6.latest can be specified with -R in which case a rootfs
will be created from rpms downloaded from the Oracle public-yum repo.
Alternatively the path to an existing rootfs of Oracle 5 or 6 may be given to
the template with the -t option.
The architecture of the downloaded rpms installed in the container can be
specified with the -a template option.
