Rather than creating a new directory and moving it there before
deleting that new directory, just move the directory we intend to
delete.
In the old way, the Mkdirall could fail, which meant that you
couldn't delete containers when the disk was full.
Tested.

This implements the new Put() operation such that
Get()/Put() maintains a refcount for each ID, mounting
only on first Get() and unmounting on the last Get().
This means we avoid littering the system with lots of mounts
and free resources related to them.

This makes all users of Put() have a corresponding call
to Get() which means we will be able to track whether
any particular ID is in use and if not unmount it.

for now unused features.

Mount is self contained and generic, it should be in pkg, to allow other pkg modules to use it.

This moves Driver.Size() to Differ.DiffSize(), removing the empty
implementations in devmapper and dummy, and renaming the one in aufs.
Then we fall back to a container.Changes() implementation in the non-aufs
case.

This will try to move the directories that were
previously symlinked until a full migration is complete.
