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.

e07d3cd9a ("devmapper: Fix libdm logging") removed all of the callers of
DmLogInitVerbose, but we still kept around the wrapper. However, the
libdm dm_log_init_verbose API changes the verbosity of the *default*
libdm logger. Because pkg/devicemapper internally *relies* on using
logging callbacks to understand what errors were encountered by libdm,
this wrapper is useless (it only makes sense for the default logger
which we do not user).
Any user not inside Docker of this function almost certainly was not
using this API correctly, because pkg/devicemapper will misbehave if our
logging callbacks were not registered.

Recent changes to devmapper broke the implicit requirement that UdevWait be
called after every call to task.setCookie. Failure to do so results in leaks of
semaphores in the LVM code, eventually leading to semaphore exhaustion.
Previously this was handled by calling UdevWait in a ubiquitous defer function.
While there was initially some concern with deferring the UdevWait function
would cause some amount of race possibiliy, the fact that we never return the
cookie value or any value used to find it, makes that possibility seem unlikely,
so lets go back to that method

Also, this removes the use of a questionable golang range feature which
corrects for mutation of a slice during iteration over that slice. This
makes the filter operation easier to read and reason about.
