Refactor device handling code

Timothy Hobbs 608702b980 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.

Eiichi Tsukata cac0cea03f drop CAP_SYSLOG capability
Kernel capabilities for privileged syslog operations are currently splitted into
CAP_SYS_ADMIN and CAP_SYSLOG since the following commit:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ce6ada35bdf710d16582cc4869c26722547e6f11

This patch drops CAP_SYSLOG to prevent containers from messing with
host's syslog (e.g. `dmesg -c` clears up host's printk ring buffer).

Closes #5491

Brandon Philips 128381e0f0 refactor(libcontainer): rename to CapabilitiesMask
The Capabilities field on libcontainer is actually used as a mask.
Rename the field so that this is more clear.

Alexander Larsson 664fc54e65 libcontainer: Initial version of cgroups support
This is a minimal version of raw cgroup support for libcontainer.
It has only enough for what docker needs, and it has no support
for systemd yet.
