This facilitates refactoring commands.go and shrinks the core.

Seriously. There's not much codebase left we haven't touched.

Runtime.Register() called driver.Get()/Put() in order to read back the
basefs of the container. However, this is not needed, as the basefs
is read during container.Mount() anyway, and basefs is only valid
while mounted (and all current calls satisfy this).
This seems minor, but this is actually problematic, as the Get/Put
pair will create a spurious mount/unmount cycle that is not needed and
slows things down. Additionally it will create a supurious
devicemapper activate/deactivate cycle that causes races with udev as
seen in https://github.com/dotcloud/docker/issues/4036.
With this change devicemapper is now race-free, and container startup
is slightly faster.

We no longer pass "pool" anywhere that uses byHash() per the last
commit, so we can now remove this hack.

Shutdown contains debug warnings like:
[debug] deviceset.go:699 [deviceset docker-0:33-17945897] waitRemove(/dev/mapper/docker-0:33-17945897-pool)
[debug] deviceset.go:380 libdevmapper(3): libdm-common.c:552 (-1) Device /dev/mapper/docker-0:33-17945897-pool not found
This is because shutdown is using removeDeviceAndWait() to remove the pool device and the
wait part fails because the pool is gone.
We fix this by adding a pool specific removal function which avoids all the trickiness of the
normal remove.

With this capability set the container can e.g. change the ip address
of his devices to that of another container on the docker0 bridge. In
a quick test I was able to listen to a port on a different ip than the
one docker assigned me, but was not able to hijack an open port
redirection that another container had open. Maybe its possible with
some more knowledge of networking though.
Anyway, network setup is meant to be handled by docker, not the apps,
so I believe denying this is generally in the spirit of docker, and
it closes down potential security issues.

If /dev/loop-control exists on the system running the test then
ioctlLoopCtlGetFree() will be called, but if not it won't. It does
not exist in the standard docker build environment, so the tests
currently require this to not be called. This makes it instead
optional, allowing the tests to run on e.g. Fedora.

We're currently leaving around lots of empty directories in
/var/lib/docker/devicemapper/mnt/ for removed images and containers.
Fix this by removing the directory when the device is removed.
