362369b4bb Adds ability to squash image after build
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.

50a498ea1c Verify layer tarstream
This adds verification for getting layer data out
of layerstore. These failures should only be possible
if layer metadata files have been manually changed
of if something is wrong with tar-split algorithm.

Failing early makes sure we don’t upload invalid data
to the registries where it would fail after someone
tries to pull it.

21278efaee Make TarStream return an io.ReadCloser
Currently, the resources associated with the io.Reader returned by
TarStream are only freed when it is read until EOF. This means that
partial uploads or exports (for example, in the case of a full disk or
severed connection) can leak a goroutine and open file. This commit
changes TarStream to return an io.ReadCloser. Resources are freed when
Close is called.

500e77bad0 Add layer store
Layer store manages read-only and read-write layers on a union file system.
Read only layers are always referenced by content addresses.
Read-write layer identifiers are handled by the caller but upon registering
its difference, the committed read-only layer will be referenced by content
hash.
