There is no need to call `os.Stat` on the driver filesystem path of a
container as `os.RemoveAll` already handles (properly) the case where
the path no longer exists.
Given the results of the stat() were not even being used, there is no
value in erroring out because of the stat call failure, and worse, it
prevents daemon cleanup of containers in "Dead" state unless you re-create
directories that were already removed via a manual cleanup after a
failure. This brings removal in overlay in line with aufs/devicemapper
drivers which don't error out if the filesystem path no longer exists.

Right now we check for the existence of device but don't make sure it is
a thin pool device. We assume it is a thin pool device and call poolStatus()
on the device which returns an error EOF. And that error does not tell
anything.
So before we reach the stage of calling poolStatus() make sure we are working
with a thin pool device otherwise error out.

This patch creates interfaces in builder/ for building Docker images.
It is a first step in a series of patches to remove the daemon
dependency on builder and later allow a client-side Dockerfile builder
as well as potential builder plugins.
It is needed because we cannot remove the /build API endpoint, so we
need to keep the server-side Dockerfile builder, but we also want to
reuse the same Dockerfile parser and evaluator for both server-side and
client-side.
builder/dockerfile/ and api/server/builder.go contain implementations
of those interfaces as a refactoring of the current code.

Start a goroutine which runs every 30 seconds and if there are deferred
deleted devices, it tries to clean those up.
Also it moves the call to cleanupDeletedDevices() into goroutine and
moves the locking completely inside the function. Now function does not
assume that device lock is held at the time of entry.

Finally here is the patch to implement deferred deletion functionality.
Deferred deleted devices are marked as "Deleted" in device meta file.
First we try to delete the device and only if deletion fails and user has
enabled deferred deletion, device is marked for deferred deletion.
When docker starts up again, we go through list of deleted devices and
try to delete these again.

Provide a command line option dm.use_deferred_deletion to enable deferred
device deletion feature. By default feature will be turned off.
Not sure if there is much value in deferred deletion being turned on
without deferred removal being turned on. So for now, this feature can
be enabled only if deferred removal is on.

Currently during startup we walk through all the device files and read
their device ID and mark in a bitmap that device id is used.
We are anyway going through all device files. So we can as well load all
that data into device hash map. This will save us little time when
container is actually launched later.
Also this will help with later patches where cleanup deferred device
wants to go through all the devices and see which have been marked for
deletion and delete these.
So re-organize the code a bit.
