The storage library uses github.com/pkg/errors to wrap errors that it
returns from many of its functions, so when passing them to
os.IsNotExist() or comparing them to specific errors defined in the
storage library, unwrap them using errors.Cause().

update libkpod's New() function to use a config struct, and update

If sandbox is in the same package as server, there will be a circular dependency when
kpod create is implemented

Move container state data to libkpod, separate from the sandbox
data in server. However, the move was structured such that sandbox
data could easily be moved over into libkpod in the future

Move non-kubernetes-dependent portions of server struct to libkpod.
So far, only the struct fields have been moved and not their dependent
functions

Container runtimes provide different levels of isolation, from kernel
namespaces to hardware virtualization. When starting a specific
container, one may want to decide which level of isolation to use
depending on how much we trust the container workload. Fully verified
and signed containers may not need the hardware isolation layer but e.g.
CI jobs pulling packages from many untrusted sources should probably not
run only on a kernel namespace isolation layer.
Here we allow CRI-O users to define a container runtime for trusted
containers and another one for untrusted containers, and also to define
a general, default trust level. This anticipates future kubelet
implementations that would be able to tag containers as trusted or
untrusted. When missing a kubelet hint, containers are trusted by
default.
A container becomes untrusted if we get a hint in that direction from
kubelet or if the default trust level is set to "untrusted" and the
container is not privileged. In both cases CRI-O will try to use the
untrusted container runtime. For any other cases, it will switch to the
trusted one.

We use a SOCK_SEQPACKET socket for the attach unix domain socket, which
means the kernel will ensure that the reading side only ever get the
data from one write operation. We use this for frameing, where the
first byte is the pipe that the next bytes are for. We have to make sure
that all reads from the socket are using at least the same size of buffer
as the write side, because otherwise the extra data in the message
will be dropped.
This also adds a stdin pipe for the container, similar to the ones we
use for stdout/err, because we need a way for an attached client
to write to stdin, even if not using a tty.

The bug is silly if you have a master/node cluster where node is on a
different machine than the master.
The current behavior is to give our addresses like "0.0.0.0:10101". If
you run "kubectl exec ..." from another host, that's not going to work
since on a different host 0.0.0.0 resolves to localhost and kubectl
exec fails with:
error: unable to upgrade connection: 404 page not found
This patch fixes the above by giving our correct addresses for reaching
from outside.

Some runtimes like Clear Containers need to interpret the CRI-O
annotations, to distinguish the infra container from the regular one.
Here we export those annotations and use a more standard dotted
namespace for them.

During "Port forwarding" e2e tests, the following panic happened:
```
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x64981d]
goroutine 52788 [running]:
panic(0x1830ee0, 0xc4200100c0)
/usr/lib/golang/src/runtime/panic.go:500 +0x1a1
github.com/kubernetes-incubator/cri-o/oci.(*Runtime).UpdateStatus(0xc4202afc00,
0x0, 0x0, 0x0)

+0x7d
github.com/kubernetes-incubator/cri-o/server.streamService.PortForward(0xc42026e000,

0xc4201cd0e0, ...)
```
The issue is `streamService.PortForward` assumed the first argument to
be the sandbox's infra container ID, thus trying to get it from memory
store using `.state.containers.Get`. Since that ID is of the sandbox
itself, it fails to get the container object from memory and panics in
`UpdateStatus`.
Fix it by looking for the sandbox's infra container ID starting from a
sandbox ID.

The ocid project was renamed to CRI-O, months ago, it is time that we moved
all of the code to the new name. We want to elminate the name ocid from use.
Move fully to crio.
Also cric is being renamed to crioctl for the time being.
