Add notes to README.md about needing to install ostree-devel, or
libostree-dev, or building ostree from source.

Bump containers/image (pulling in its new dependency on ostree-go),
containers/storage, and updated image-spec.
This pulls in the OCI v1.0 specifications and code that allows us to
support 1.0 images.

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

During my testing in OpenShift I've noticed that conmon leaves some
zombies processes. The reason is that we are using
PR_SET_CHILD_SUBREAPER in conmon and runC forks a new process (runc
init) each time we start a container. Using g_child_watch_add only on
the main runc process and on the container process is not enough as we
do not cleanup any other zombie process.
Since glib doesn't allow to catch SIGCHLD and to better integrate in the
existing code, catch it with signal(2) then raise a SIGUSR1 that glib
handles.

bin2img/checkseccomp/copyimg are file targets and should not be .PHONY.
This prevents to build them if not necessary.

Build all of our binaries with the same build tags and the same LDFLAGS.
This means we add $(LDFLAGS) to bin2img, copyimg, and cri-o,
$(BUILDTAGS) to kpod, and both to crioctl and checkseccomp.

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

When the integration test image is run on a system with apparmor
enabled, it needs binaries from the 'apparmor' package, so ensure that
it's always there.

Basically none of the clever storage drivers will work when we're on top
of AUFS, so if we find ourselves in that situation when running tests,
default to storage options of "--storage-driver vfs".

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

go list {{.Imports}} outputs imports as an array, and the leading
and trailing square brackets can get caught in the name of a package.
Add a pipe in the dependency command to remove the brackets

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

Use unix.Prctl() instead of manually reimplementing it using
unix.RawSyscall. Also use unix.SECCOMP_MODE_FILTER instead of locally
defining it.

Design: The output of the `info` subcommand ought to be directly
consumable in a format like JSON or yaml.
The structure being a map of sorts.
Each subsection of information being an individual cluster under the
top-level, like platform info, debug, storage, etc.
Even if there are errors under the top level key, the value will be a
map with the key of "error" and the value as the message of the
`err.Error()`. In this way, the command always returns usable output.
Ideally there will be a means for anything that can register info to do
so independently from it being in the single info.go, so this approach
is having a typed signature for the function that gives info, but i'm
sure it could be better.
Current iteration of this outputs the following as a limited user:
```yaml
host:
MemFree: 711307264
MemTotal: 2096222208
SwapFree: 2147479552
SwapTotal: 2147479552
arch: amd64
cpus: 1
os: linux
store:
error: 'mkdir /var/run/containers/storage: permission denied'
```
and as root (`sudo kpod info -D`):
```yaml
debug:
compiler: gc
go version: go1.7.6
goroutines: 3
host:
MemFree: 717795328
MemTotal: 2096222208
SwapFree: 2147479552
SwapTotal: 2147479552
arch: amd64
cpus: 1
os: linux
store:
ContainerStore:
number: 1
GraphDriverName: overlay2
GraphRoot: /var/lib/containers/storage
ImageStore:
number: 1
```
And with the `--json --debug` flag:
```json
{
"debug": {
"compiler": "gc",
"go version": "go1.7.6",
"goroutines": 3
},
"host": {
