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.

1. All titles are listed by simple platform names apart from Windows' "Installing Docker On Windows". Changed this to "Windows" to match the rest.
2. Some articles' description (and title) information does not match the majority. Modified them to match the rest (i.e. Please note this project is currently under heavy development. It should not be used in production.)
3. Removed "Linux" from Gentoo & Ubuntu descriptions.

This way, packagers can set GIT_DIR appropriately if they'd prefer to not have ".git" inside their working directory.

This also adds a new "AUTO_GOPATH" environment variable that will create an appropriate GOPATH as part of the build process.

This makes the device mapper not zero out blocks allocated on the
thinp device. This is safe in our use case, as we access the device
via a filesystem that doesn't leak any uninitialized data to userspace.
This partially helps with https://github.com/dotcloud/docker/issues/3280
and should generally improve preformance on the devicemapper backend.
