Nicholas Weaver 8597998244 Fixes logic for calculating percentage for cgroups.Stats.CpuStats.CpuUsage.PercentUsage
Previous logic divided a uint64 by a uint64 losing precision before multiplying by clock ticks and cpus
This fix maintains precision before converting back to uint64

Peter Bourgon c6edb4ad96 Only import "testing" from *_test.go
This prevents the testing package flags from leaking into the
flagsets of binaries that import libcontainer.

Vishnu Kannan 66aee74b1e Libcontainer fs.GetStats() will not look for cgroups relative to the cgroup of init process if the parent
in cgroups.Cgroup is absolute. This is required to get stats of other containers while running inside a docker container.

Victor Marmol 8de8fe9272 Remove FreezerStats.
They are really freezer state and we'll move them through another
interface.

Rohit Jnagal d712d29b9a Add a cleanup method to cgroup fs. This will help in building a
standalone cgroup test util. systemd does auto cleanup on empty, so
doesn't need an extra interface.

Michael Crosby 5d1ebaf4c3 Implement systemd support for freezer
These PR does a few things.  It ensures that the freezer cgroup is
joined in the systemd driver.  It also provides a public api for setting
the freezer state via the cgroups package.

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.
