This allows clients to specify that LLB states should be grouped in
progress output under a custom name. Status updates for all vertexes in
the group will show up under a single vertex in the output.
The intended use cases are for Dockerfile COPY's that use MergeOp as a
backend and for grouping some other internal vertexes during frontend
builds.

This consists of just the base MergeOp with support for merging LLB
results that include deletions using hardlinks as the efficient path
and copies as fallback.

Lots of client implementations have been already depending on the
current controller API, so the API should not be considered experimental.

Export:
$ buildctl build ... --export-cache type=local,store=/path/to/output-dir
Import:
$ buildctl build ... --import-cache type=local,store=/path/to/input-dir
Impact on CLI:
* Old (deprecated but still effective): `--export-cache localhost:5000/myrepo:buildcache --export-cache-opt mode=max`
* New: `--export-cache type=registry,ref=localhost:5000/myrepo:buildcache,mode=max`
Impact on API:
* New fields are added to control.proto and gateway.proto. The daemon
internally translates old API calls to the new ones.
* While new API can be used for `registry` caches, the client continues
to use the legacy API for `registry` caches to ensure compatibility with
old daemons.
* To import `local` caches with a frontend, the frontend needs to support
a new frontend opt `cache-imports`.

Modelled after the vendor support provide a validator and an updator for files
produced by `go generate` (which today just means `*.pb.go`).
Main difference from the vendor support is that we are no longer simply nuking
and replacing a single directory, so I ended up hardcoding `*.pb.go` in a bunch
of places which I don't like but cannot see a way around which doesn't risk
nuking people's other local changes.
The generated files are placed in an unpacked form in a `FROM scratch`
container for update. Use a subdirectory and `tar --strip-components` (portable
to MacOS and Linux according to `tar(1)`) since trying to do a `docker export`
of just the root ends up adding `.dockerenv`, `sys`, `proc` and `dev` to the
source tree.
The validate container is not `FROM scratch` because we want `cat`.
The run in `frontend/gateway/pb/generate.go` was missing an include so fix
that.
The versions of `protoc` and the gogo plugins were chosen to regenerate the
existing code as closely as possible. The updates to `*.pg.go` here are all the
result of regenerating with go1.9 which fixed
https://github.com/golang/go/issues/17663 and replaced an invalid timestamp in
the gzip header of the data encoded in `fileDescriptor*`, and adopted a new
standard for marking generated files.
Finally, I noticed that my `docker run`s were missing an `--rm` which I
inherited from `validate-vendor`, so fix all those.
Closes: #322
