init layer is read/write layer and not read only layer. Following commit
introduced new graph driver method CreateReadWrite.
ef5bfad Adding readOnly parameter to graphdriver Create method
So far only windows seem to be differentiating between above two methods.
Making this change to make sure -init layer calls right method so that
we don't have surprises in future.
Windows does not need init layer. This patch also gets rid of creation of
init layer on windows.

Windows base layers are no longer the special "layers+base" type, so we can remove all the special handling for that.

This adds an `--oom-score-adjust` flag to the daemon so that the value
provided can be set for the docker daemon's process. The default value
for the flag is -500. This will allow the docker daemon to have a
less chance of being killed before containers do. The default value for
processes is 0 with a min/max of -1000/1000.
-500 is a good middle ground because it is less than the default for
most processes and still not -1000 which basically means never kill this
process in an OOM condition on the host machine. The only processes on
my machine that have a score less than -500 are dbus at -900 and sshd
and xfce( my window manager ) at -1000. I don't think docker should be
set lower, by default, than dbus or sshd so that is why I chose -500.

Now that Windows base images can be loaded directly into docker via "docker load" of a specialized tar file (with docker pull support on the horizon) we no longer have need of the custom images code path that loads images from a shared central location. Removing that code and it's call points.

Previously, Windows only supported running with a OS-managed base image.
With this change, Windows supports normal, Linux-like layered images, too.

Fixes an issue that prevents nano server images from loading properly. Also updates logic for custom image loading to avoid preventing daemon start because an image failed to load.

These fields are needed to specify the exact version of Windows that an
image can run on. They may be useful for other platforms in the future.
This also changes image.store.Create to validate that the loaded image is
supported on the current machine. This change affects Linux as well, since
it now validates the architecture and OS fields.
