When running on a kernel which is not patched for the copy up bug
overlay2 will use the naive diff driver.

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

The overlay2 change ensures that the correct path is used to resolve the
symlink. The current code will not fail since the symlinks are always given
a value of "../id/diff" which ends up ignoring the incorrect "link" value.
Fix this code so it doesn't cause unexpected errors in the future if the
symlink changes.
The layerstore cleanup ensures that the empty layer returns a tar stream if
the provided parent is empty. Any value other than empty still returns an
error since the empty layer has no parent. Currently empty layer is not
used anywhere that TarStreamFrom is used but could break in the future if
this function is called.

Allow built images to be squash to scratch.
Squashing does not destroy any images or layers, and preserves the
build cache.
Introduce a new CLI argument --squash to docker build
Introduce a new param to the build API endpoint `squash`
Once the build is complete, docker creates a new image loading the diffs
from each layer into a single new layer and references all the parent's
layers.

Now that overlay has matured, using
overlay is a better choice than devicemapper
on loopback devices.
This change promotes overlay in the
priority list. It also adds the
overlay2 graphdriver to the list
because overlay2 (if supported)
should be preferred over overlay.

The `archive` package defines aliases for `io.ReadCloser` and
`io.Reader`. These don't seem to provide an benefit other than type
decoration. Per this change, several unnecessary type cases were
removed.

Go can falsely report a larger page size than supported,
causing overlay2 mount arguments to be truncated. When overlay2
detects the mount arguments have hit the page limit, it will
switch to using relative paths. If this limit is smaller than
the actual page size there is no behavioral problems, but if it
is larger mounts can fail for images with many layers.

In kernel version >= v4.5 the project quota ioctl definitions
have been made public via the include/uapi/linux/fs.h API, so
that ext4 could use the same API.
Avoid re-defining the ioctl API if it is already defined in fs.h.

Allow passing --storage-opt size=X to docker create/run commands
for the `overlay2` graphriver.
The size option is only available if the backing fs is xfs that is
mounted with the `pquota` mount option.
The user can pass any size less then the backing fs size.

This class implements XFS project quota controls
for setting quota limits on a newly created directory.
It currently supports the legacy XFS specific ioctls.
Using this class, quota limits per container can be set
by directory based storage drivers (e.g. overlay), when
backing storage is XFS mounted with 'pquota' mount option.
TODO: use generic quota control ioctl FS_IOC_FS{GET,SET}XATTR
for both xfs/ext4 for kernel version >= v4.5

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.
