- Implements mixed mode for /sys where it's mounted read-only but with
/sys/devices/virtual/net/ writable.
- Sets lxc.mount.auto to "cgroup:mixed proc:mixed sys:mixed" for all
templates.
- Drop any template-specific mount for /proc, /sys or /sys/fs/cgroup.
- Get rid of the fstab file by default, using lxc.mount.entry instead.
- Set sys:mixed as the default for "sys". sys:mixed is slightly more
permissive than sys:ro so this shouldn't be a problem.
The read-only bind mount of /sys on top of itself is there so that
mountall and other init systems don't attempt to remount /sys
read-write.
v2 changes:
- Fix the mount list, don't specify a source for the remount.
- Update the documentation.

It's now been proven over and over again that the symlink from /dev/kmsg
to /dev/console is harmful for everything but upstart systems. As Ubuntu
is now switching over to systemd too, lets switch the default.
Upstart users wishing to see boot messages can always set lxc.kmsg = 1
manually in their config (so long as they don't expect to then
dist-upgrade the container to systemd succesfuly).

Now that autodev works fine with unprivileged containers and shouldn't
come with any side effect, lets turn it on by default.

This idea came from Andy Lutomirski. Instead of using a
temporary directory for the pivot_root put-old, use "." both
for new-root and old-root. Then fchdir into the old root
temporarily in order to unmount the old-root, and finally
chdir back into our '/'.
Drop lxc.pivotdir from the lxc.container.conf manpage.
Warn when we see a lxc.pivotdir entry (but keep it in the
lxc.conf for now).

This patch adds support for checkpointing and restoring containers via CRIU.
It adds two api calls, ->checkpoint and ->restore, which are wrappers around
the CRIU CLI. CRIU has an RPC API, but reasons for preferring exec() are
discussed in [1].
To checkpoint, users specify a directory to dump the container metadata (CRIU
dump files, plus some additional information about veth pairs and which
bridges they are attached to) into this directory. On restore, this
information is read out of the directory, a CRIU command line is constructed,
and CRIU is exec()d. CRIU uses the lxc-restore-net callback (which in turn
inspects the image directory with the NIC data) to properly restore the
network.
This will only work with the current git master of CRIU; anything as of
a152c843 should work. There is a known bug where containers which have been
restored cannot be checkpointed [2].

v2: fixed some problems with the s/int/bool return code form api function
v3: added a testcase, fixed up the man page synopsis
v4: fix a small typo in lxc-test-checkpoint-restore
v5: remove a reference to the old CRIU_PATH, and a bad error about the same

v2: add get_config_item
clear_config_item is not supported, as it isn't for lxc.console, bc
you can do 'lxc.console.logfile =' to clear it. Likewise save_config
is not needed because the config is now just written through the
unexpanded char*.
