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.

This will help with debugging as one could just do "docker info" and figure
out of deferred removal is enabled or not.

Provide a new command line knob dm.deferred_device_removal which will enable
deferred device deactivation if driver and library support it.
This patch also checks for library support and driver version.

A lot of time device mapper devices leak across mount namespace which docker
does not know about and when docker tries to deactivate/delete device,
operation fails as device is open in some mount namespace.
Create a mechanism where one can defer the device deactivation/deletion
so that docker operation does not fail and device automatically goes
away when last reference to it is dropped.

libdm started offering deferred remove functionality from version
1.02.89. As docker still builds against older libdm, define a tag
libdm_no_deferred_remove to determine whether we are compiling
against new libdm or older one and enable/disable deferred remove
functionality accordingly.

Thanks to @dmcgowan for noticing.
Added a testcase to make sure Save() can create the dir and then
read from it.

Though I am not clear on the intent of the sentence if it means that existing data in the base image is copied into the new volume then the additions I propose make that more clear than the present language.

This PR does the following:
- migrated ~/.dockerfg to ~/.docker/config.json. The data is migrated
but the old file remains in case its needed
- moves the auth json in that fie into an "auth" property so we can add new
top-level properties w/o messing with the auth stuff
- adds support for an HttpHeaders property in ~/.docker/config.json
which adds these http headers to all msgs from the cli
In a follow-on PR I'll move the config file process out from under
"registry" since it not specific to that any more. I didn't do it here
because I wanted the diff to be smaller so people can make sure I didn't
break/miss any auth code during my edits.
