devmapper graph driver retries device removal 1000 times in case of failure
and if this fills up console with 1000 messages (when daemon is running in
debug mode). So remove these debug messages.

There are issues with libdm logging. Right now if docker daemon is run
in debug mode, logging by libdm is too verbose. And if a device can't
be removed, thousands of messages fill the console and one can not see
what's going on.
This patch removes devicemapper.LogInitVerbose() call as that call will
only work if docker was not registering its own log handler with libdm.
For some reason docker registers one with libdm and libdm hands over
all the messages to docker (including debug ones). And now it is up to
devmapper backend to figure out which ones should go to console and
which ones should not.
So by default log only fatal messages from libdm. One can easily modify
the code to change it for debugging purposes.

I have seen a lot of people try to do this and reach out to me on how to mount
/dev/snd because it is returning "not a device node". The docs imply you can
_just_ mount /dev/snd and that is not the case. This fixes that. It also allows
for coolness if you want to mount say /dev/usb.

When working with Go channels you must not set it to nil or else the
channel will block forever. It will not panic reading from a nil chan
but it blocks. The correct way to do this is to create the channel then
close it as the correct results to the caller will be returned.

I can never get it to work for me when its just 3 seconds.
With this change it generates the OOM message around 17 seconds, but
I increased the timeout to 30 for people with slower machines

This makes `registry.Service` a first class type and does not use jobs
to interact with this type.

Syslog was a heading-2, but should be heading-3;
changed the headings to heading-4 to match the
"network settings" section.
Also changed "Log driver" to "logging driver" for JSON.

Closing activationLock only if it's not closed already. This is needed
only because integration tests using docker code directly and doesn't
care about global state.

It's about time to let folks not hit 'vfs', when 'overlay' is supported
on their kernel. Especially now that v3.18.y is a long-term kernel.
