This adds daemon/graphdriver/graphtest/graphtest which has a few
generic tests for all graph drivers, and then uses these
from the btrs, devicemapper and vfs backends.
I've not yet added the aufs backend, because i can't test that here
atm. It should work though.

Currently the tests that mocks or denies functions leave this state
around for the next test. This is no good if we want to actually
test the devicemapper code in later tests.

This has every container using the docker daemon's pid for the processes
label so it does not work correctly.

This allows multiple instances of the backend in different containers
to access devices (although generally only one can modify/create them).
Any old metadata is converted on the first run.

We used to mount in Create() to be able to create a few files that
needs to be in each device. However, this mount is problematic for
selinux, as we need to set the mount label at mount-time, and it
is not known at the time of Create().
This change just moves the file creation to first Get() call and
drops the mount from Create(). Additionally, this lets us remove
some complexities we had to avoid an extra unmount+mount cycle.
