LogInit used to act as a manual way of registering the *necessary*
pkg/devicemapper logging callbacks. In addition, it was used to split up
the logic of pkg/devicemapper into daemon/graphdriver/devmapper (such
that some things were logged from libdm).
The manual aspect of this API was completely non-sensical and was just
begging for incorrect usage of pkg/devicemapper, so remove that semantic
and always register our own libdm callbacks.
In addition, recombine the split out logging callbacks into
pkg/devicemapper so that the default logger is local to the library and
also shown to be the recommended logger. This makes the code
substantially easier to read. Also the new DefaultLogger now has
configurable upper-bound for the log level, which allows for dynamically
changing the logging level.

If a device has been scheduled for deferred deactivation and container
is started again and we need to activate device again, we need to cancel
the deferred deactivation which is already scheduled on the device.
Create a method for the same.
