devmapper: Fix prefix name to work with udev

Udev escapes "," used in device names to 0\x2c which breaks libdevmapper.
Instead use : to escape minor and minor which works.

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.

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.

devicemapper: Serialize addess to the devicemapper deviceset
This code is not safe to run in multiple threads at the same time,

DeviceMapper: Move deactivate into UnmountDevice
This way the deactivate is atomic wrt othe device mapper operations
and will not fail with EBUSY if someone else starts a devicemapper
operation inbetween unmount and deactivate.
devmapper: Fix loopback mounting regression
Some changes were added to attach_loop_device which added
a perror() in a place that caused it to override errno so that
a later errno != EBUSY failed. This fixes that and cleans up
the error reporting a bit.
