At the moment vendor.conf is missing entries for `github.com/tonistiigi/llb-gobuild`
and `github.com/morikuni/aec` due in part because of a combination of
https://github.com/LK4D4/vndr/issues/62 and https://github.com/LK4D4/vndr/issues/63.
The issue vndr#63 (related to lack of `github.com/morikuni/aec`) can be worked
around by removing the vendor directory before rerunning `vndr`, so do so.
Due to vndr#62 the issue with `github.com/tonistiigi/llb-gobuild` cannot be
detected at the moment, but pass `-strict` to `vndr` in anticipation of a fix
there.

When using `--frontend=gateway.v0` in order to use a tagged image as the
frontend it is currently required to push the tag to a registry, so that
buildkit can pull it. One can use the `image@sha256:digest` form but this is
inconvenient for the development cycle.
Instead, introduce a proxy `Resolver` which if the pull fails checks the local
image store (if there is one, which is worker dependent) for a suitable image
and if so uses that.
With this I can now:
buildctl build --frontend=dockerfile.v0 --local context=. --local dockerfile=. --exporter=image --exporter-opt=name=docker.io/ijc25/fe:dev
builtctl build --frontend=gateway.v0 --frontend-opt=source=ijc25/fe:dev --exporter=image --exporter-opt=name=hello-world:dev
Without any push to a registry.
I am using the containerd worker.

The previous code had 3 issues:
- The original schema 1 manifest remained in `ongoing.added` but was not added
to the content store by the conversion. #296 tried to address this in an
incorrect way and was reverted by the previous commit. Instead switch in the
schema2 manifest, which was otherwise missed.
- Empty layers in the schema 1 manifest are not propagated to the schema 2
version, meaning they are not referenced by anything and hence are never
freed up and therefore leak
- The new schema 2 image config is generated by the converter and not fetched,
so it never passes through the `HandlerFunc` which adds things to
`ongoing.added`.
Two address these last two bullets when processing a schema 1 image walk over
the converted image and together with `ongoing.added` produce lists of used and
unused blobs, use the list of used blobs to perform the GC updates and simply
delete everything on the unused list.
Closes: #301.

This reverts commit 92101de156 from #296.
This was the wrong approach a subsequent commit will fix this properly.

The behaviour of `github.com/containerd/containerd/remotes/docker/schema1` is
such that the manifest is not actually in the content store, so attempting to
delete it fails with `NotFound`, which with the `gateway.v0` frontend results
in:
time="2018-02-26T17:01:15Z" level=error msg="fatal error: rpc error: code = Unknown desc = content digest sha256:178598e51a26abbc958b8a2e48825c90bc22e641de3d31e18aaf55f3258ba93b: not found"
panic: rpc error: code = Unknown desc = content digest sha256:178598e51a26abbc958b8a2e48825c90bc22e641de3d31e18aaf55f3258ba93b: not found
It seems safe to just ignore these errors, since `NotFound` is what we wanted
after delete anyway.
This allows support for e.g. `llb.Image("docker.io/docker/whalesay:latest")`
