This allows for easy extension of adding more parameters to existing
parameters list. Otherwise adding a single parameter changes code
at so many places.

As part of making graphdrivers support pluginv2, a PluginGetter
interface was necessary for cleaner separation and avoiding import
cycles.
This commit creates a PluginGetter interface and makes pluginStore
implement it. Then the pluginStore object is created in the daemon
(rather than by the plugin manager) and passed to plugin init as
well as to the different subsystems (eg. graphdrivers, volumedrivers).
A side effect of this change was that some code was moved out of
experimental. This is good, since plugin support will be stable soon.

Currently when overlay creates a whiteout file then the overlay2 layer is archived,
the correct tar header will be created for the whiteout file, but the tar logic will then attempt to open the file causing a failure.
When tar encounters such failures the file is skipped and excluded for the archive, causing the whiteout to be ignored.
By skipping the copy of empty files, no open attempt will be made on whiteout files.

Overlay tests were failing when /var/tmp was an overlay mount with a misleading message.
Now overlay tests will be skipped when attempting to be run on overlay.
Tests will now use the TMPDIR environment variable instead of only /var/tmp

Since the layer store was introduced, the level above the graphdriver
now differentiates between read/write and read-only layers. This
distinction is useful for graphdrivers that need to take special steps
when creating a layer based on whether it is read-only or not.
Adding this parameter allows the graphdrivers to differentiate, which
in the case of the Windows graphdriver, removes our dependence on parsing
the id of the parent for "-init" in order to infer this information.
This will also set the stage for unblocking some of the layer store
unit tests in the next preview build of Windows.

This change will allow us to run SELinux in a container with
BTRFS back end. We continue to work on fixing the kernel/BTRFS
but this change will allow SELinux Security separation on BTRFS.
It basically relabels the content on container creation.
Just relabling -init directory in BTRFS use case. Everything looks like it
works. I don't believe tar/achive stores the SELinux labels, so we are good
as far as docker commit.
Tested Speed on startup with BTRFS on top of loopback directory. BTRFS
not on loopback should get even better perfomance on startup time. The
more inodes inside of the container image will increase the relabel time.
This patch will give people who care more about security the option of
runnin BTRFS with SELinux. Those who don't want to take the slow down
can disable SELinux either in individual containers or for all containers
by continuing to disable SELinux in the daemon.
Without relabel:
> time docker run --security-opt label:disable fedora echo test

With Relabel

Adds support for the daemon to handle user namespace maps as a
per-daemon setting.
Support for handling uid/gid mapping is added to the builder,
archive/unarchive packages and functions, all graphdrivers (except
Windows), and the test suite is updated to handle user namespace daemon
rootgraph changes.

Ploop graph driver provides its own ext4 filesystem to every
container. It so happens that ext4 root comes with lost+found
directory, causing failures from DriverTestCreateEmpty() and
DriverTestCreateBase() tests on ploop.
While I am not yet ready to submit ploop graph driver for review,
this change looks simple enough to push.
Note that filtering is done without any additional allocations,
as described in https://github.com/golang/go/wiki/SliceTricks.
[v2: added a comment about lost+found]

There are two cases where we can't use a graphdriver:
1) the graphdriver itself isn't supported by the system
2) the graphdriver is supported by some configuration/prerequisites are
missing
This introduces a new error for the 2) case and uses it when trying to
run docker with btrfs backend on a non-btrfs filesystem.

This adds daemon/graphdriver/graphtest/graphtest which has a few
generic tests for all graph drivers, and then uses these
from the btrs, devicemapper and vfs backends.
I've not yet added the aufs backend, because i can't test that here
atm. It should work though.
