a14496ce89 Devmapper: Mount images readonly when calculating changes 
There is no need to have this be writable, and there is a chance
that e.g. atime updates will cause writes to the image which is
bad for disk use wrt sharing between all containers.

8abcc8e713 devmapper: Use a smaller blocksize for the thin-pool 
As per the thin provisioning docs for creating the pool:

   $data_block_size gives the smallest unit of disk space that can be
   allocated at a time expressed in units of 512-byte sectors.
   $data_block_size must be between 128 (64KB) and 2097152 (1GB) and a
   multiple of 128 (64KB). $data_block_size cannot be changed after the
   thin-pool is created. People primarily interested in thin provisioning
   may want to use a value such as 1024 (512KB). People doing lots of
   snapshotting may want a smaller value such as 128 (64KB).

The switch from 512 (which we used before) to 128 (recommended above
for lots of snapshoting) means a simple container creation (based on the
mattdm/fedora:f19 image) adds 1 MB of diskspace rather than 3.6.
This seems more in tune with how docker is typically used.

0aee096fd7 TarFilter: Fix leak of tmpfiles 
We were leaking the temporary directory that we create in TarFilter,
because the "tmpDir, err := ioutil.TempDir()" call overrides the
tmpDir in the outer scope with a new locally scoped variable.
This means tmpDir is always "" when the cleanup function is called.

Also, we did not call the atExit() function if CmdStream had an
error early on.

On errors in CmdStream(),

e6a73e65a2 devicemapper: Use device/inode of the root dir, not the image 
This way the devicemapper prefix stays stable even if we're not
using loopback mounted devices.
