devmapper: use proper DM_UDEV_DISABLE_*_FLAG when creating the thin-pool

Otherwise udev can unecessarily execute various rules (and issue
scanning IO, etc) against the thin-pool -- which can never be a
top-level device.

devmapper: Add option for specifying an lvm2 created thin-pool device

Ideally lvm2 would be used to create/manage the thin-pool volume that is
then handed to docker to exclusively create/manage the thin and thin
snapshot volumes needed for it's containers.  Managing the thin-pool
outside of docker makes for the most feature-rich method of having
docker utilize device mapper thin provisioning as the backing storage
for docker's containers.  lvm2-based thin-pool management feature
highlights include: automatic or interactive thin-pool resize support,
dynamically change thin-pool features, automatic thinp metadata checking
when lvm2 activates the thin-pool, etc.

Docker will not activate/deactivate the specified thin-pool device but
it will exclusively manage/create thin and thin snapshot volumes in it.

Docker will not take ownership of the specified thin-pool device unless
it has 0 data blocks used and a transaction id of 0.  This should help
guard against using a thin-pool that is already in use.

Also fix typos in setupBaseImage() relative to the thin volume type of
the base image.

Corrected description of --sig-proxy

Signal proxy does work only in non-TTY mode (--tty=false). Man pages and
commands should not lie about it.

fix missing layers when exporting a full repository

Therer is a bug in the 'skip' decision when exporting a repository
(`docker save repo`)

Only the layers of the first image are included in the archive (the
layers of the next images are missing)

devmapper: Call UdevWait() even in failure path

Currently we set up a cookie and upon failure not call UdevWait(). This
does not cleanup the cookie and associated semaphore and system will
soon max out on total number of semaphores.

To avoid this, call UdevWait() even in failure path which in turn will
cleanup associated semaphore.

Be clearer in docs about COPY/ADD dirs
COPY/ADD just copies the contents of dirs, not dirs themselves.
This PR tries to clear that up in the docs.
