Bug#673000: lvm2: enabling dm-thin is currently dangerous

Thin provisioning is still 'experimental' but users should try to use
and report bugs and problems.

As for thin_check tool - user could elimitnate it's usage by setting:

/etc/lvm/lvm.conf    global { thin_check_executable="" }     # empty string

But in general checks should not be skipped!
Currently are being done before activation and after deactivation of thin pool.

thin utils should be probably packaged as separate package -
They are usable with dmsetup, they do not depend on lvm2.

Unsure about  lvm2 dependency - since thin utils are only needed if user plans
to use thin provisioning - and they have C++ deps - thus it adds some extra
libs to the core system.
