Naivediff fails when layers are created directly on top of
each other. Other graphdrivers which use naivediff already
skip these tests. Until naivediff is fixed, skip with overlay2
when running tests on a kernel which causes naivediff fallback.
Fix applydiff to never use the naivediff size when not applying
changes with naivediff.

When running on a kernel which is not patched for the copy up bug

This allows for easy extension of adding more parameters to existing

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.

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.

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.

In the common case where the user is using /var/lib/docker and
an image with less than 60 layers, forking is not needed. Calculate
whether absolute paths can be used and avoid forking to mount in
those cases.

Adds a new overlay driver which uses multiple lower directories to create the union fs.
Additionally it uses symlinks and relative mount paths to allow a depth of 128 and stay within the mount page size limit.
Diffs and done directly over a single directory allowing diffs to be done efficiently and without the need fo the naive diff driver.
