Currently the LXC driver can only populate filesystems from
host filesystems, using bind mounts. This patch allows host
block devices to be mounted. It autodetects the filesystem
format at mount time, and adds the block device to the cgroups
ACL. Example usage is
<filesystem type='block' accessmode='passthrough'>
<source dev='/dev/sda1'/>
<target dir='/home'/>
</filesystem>
* src/lxc/lxc_container.c: Mount block device filesystems
* src/lxc/lxc_controller.c: Add block device filesystems
to cgroups ACL

ACK with those typo fixes.
