If device is being reactivated before it could go away and deferred
deactivation is scheduled on it, cancel it.

Deferred reove functionality was added to library later. So in old version
of library it did not report deferred_remove field.
Create a new function which also gets deferred_remove field and it will be
called only on newer version of library.

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.

When ever something vendor/ changes the go dependencies have to downloaded again,
which requires internet access and there for is potential slow. COPY and go install is much faster, while the git urls does not change not this often.
