Fix root directory of the mountpoint being owned by real root. This is
unique to ZFS because of the way file mountpoints are created using the
ZFS tooling, and the remapping that happens at layer unpack doesn't
impact this root (already created) holding directory for the layer.

mqueue can not be mounted on the host os and then shared into the container.
There is only one mqueue per mount namespace, so current code ends up leaking
the /dev/mqueue from the host into ALL containers. Since SELinux changes the
label of the mqueue, only the last container is able to use the mqueue, all
other containers will get a permission denied. If you don't have SELinux protections
sharing of the /dev/mqueue allows one container to interact in potentially hostile
ways with other containers.

For btrfs driver, in d.Create(), Get() of parentDir is called but not followed
by Put().
If we apply SElinux mount label, we need to mount btrfs subvolumes in d.Get(),
without a Put() would end up with a later Remove() failure on
"Device resourse is busy".
This calls the subvolume helper function directly in d.Create().

Currently some commands including `kill`, `pause`, `restart`, `rm`,
`rmi`, `stop`, `unpause`, `udpate`, `wait` will print a lot of error
message on client side, with a lot of redundant messages, this commit is
trying to remove the unuseful and redundant information for user.

This adds an npipe protocol option for Windows hosts, akin to unix
sockets for Linux hosts. This should become the default transport
for Windows, but this change does not yet do that.
It also does not add support for the client side yet since that
code is in engine-api, which will have to be revendored separately.

Currently, daemonbuilder package (part of daemon) implemented the
builder backend. However, it was a very thin wrapper around daemon
methods and caused an implementation dependency for api/server build
endpoint. api/server buildrouter should only know about the backend
implementing the /build API endpoint.
Removing daemonbuilder involved moving build specific methods to
respective files in the daemon, where they fit naturally.

Most storage drivers call graphdriver.GetFSMagic(home),
it is more clean to easy to maintain. So btrfs need to
adopt such change.
