Some workloads rely on IPC for communications with other processes. We
would like to split workloads between two container but still allow them
to communicate though shared IPC.
This patch mimics the --net code to allow --ipc=host to not split off
the IPC Namespace. ipc=container:CONTAINERID to share ipc between containers
If you share IPC between containers, then you need to make sure SELinux labels
match.

I noticed a few things that were bugging me in the output
of the integration-cli tests.
- one of the tests used println to stdout so we had garage sent to the screen
- some of the test, in their final log message, didn't include the name of
the group/file e.g. daemon - run,iptables was just run,iptables
And yes, I noticed this because I'm anal :-) but also because we should keep
the output of the tests as clean as possible so its easy to spot it when
things go bad.

Running parseVolumesFromSpec on all VolumesFrom specs before initialize
any mounts endures that we don't leave container.Volumes in an
inconsistent (partially initialized) if one of out mount groups is not
available (e.g. the container we're trying to mount from does not
exist).
Keeping container.Volumes in a consistent state ensures that next time
we Start() the container, it'll run prepareVolumes() again.
The attached test demonstrates that when a container fails to start due
to a missing container specified in VolumesFrom, it "remembers" a Volume
that worked.

While working on the fix for #8330 I noticed a few things:
1 - the split() call for the .dockerignore process will generate a blank
"exclude". While this isn't causing an issue right now, I got worried
that in the future some code later on might interpret "" as something bad,
like "everything" or ".". So I added a check for an empty "exclude"
and skipped it
2 - if someone puts "foo" in their .dockerignore then we'll skip "foo".
However, if they put "./foo" then we won't due to the painfully
simplistic logic of go's filepath.Match algorithm. To help things
a little (and to treat ./Dockerfile just like Dockerfile) I added
code to filepath.Clean() each entry in .dockerignore. It should
result in the same semantic path but ensure that no matter how the
user expresses the path, we'll match it.

Do not run containers in the background in the integration tests if you
depend on the run completing. It is better especially if you just want
to ensure that the run has completed with a `true` to just run in
foreground and use a known name for the container to query it after it
has stopped.
The failures can be reproduced on most machines by giving your dind
container one core and a cpushare.
