Michael Crosby c2a80eb59f Ensure all dev nodes are copied for privileged
This also makes sure that devices are pointers to avoid copies

Refactor device handling code

Timothy Hobbs 18f6a5aaf4 Refactor device handling code
We now have one place that keeps track of (most) devices that are allowed and created within the container.  That place is pkg/libcontainer/devices/devices.go

This fixes several inconsistencies between which devices were created in the lxc backend and the native backend.  It also fixes inconsistencies between wich devices were created and which were allowed.  For example, /dev/full was being created but it was not allowed within the cgroup.  It also declares the file modes and permissions of the default devices, rather than copying them from the host.  This is in line with docker's philosphy of not being host dependent.

Vishnu Kannan a4b8bef91b Added a new method cgroups.GetStats() which will return a cgroups.Stats object which will contain all the available cgroup Stats.
Remove old Stats interface in libcontainers cgroups package.
Changed Stats to use unit64 instead of int64 to prevent integer overflow issues.
Updated unit tests.

Vishnu Kannan 0b580ff32d Added stats.go which provides strong types for all stats that will be exported by libcontainer. This commit only introduces the strong type.
