This allows opt-in to cache key debug database on
daemon startup.
If enabled, all cache keys generated by builds are
saved into this database together with the plaintexts
of the original data so a reverse lookup can be performed
later to compare two checksums and find out their original
difference. If checksum contains other checksums internally
then these are saved as well. For storage constraints, the
plaintext of file content is not saved but the metadata
portion can be still looked up.

Convert usages of `github.com/docker/docker/pkg/idtools` to
`github.com/moby/sys/user` in order to break the dependency between
buildkit and docker.

In this case the current stack trace points to the line
where the context was created. Instead the stack should be
captured when the defer is running so the return path to
the defer call is also part of the stack.

On a build with no-cache, cache mounts were not pruned correctly
if the mount was on top of another ref. This also appeared in
Dockerfile when mode/uid/gid was set because implicit parent
ref is created in these cases in order to change the permissions
of a subdir that is used as a cache mount base.
Because it is not possible to know ahead of time what ref
will become the parent of cache mount during build, all cache
mounts matching the ID that have a parent will be pruned.

Sources are a pretty neat extension point, except there are a few code
paths that hard-code against each type. This moves code around and
adjusts interfaces so that Source implementations are self-contained and
merely need to be registered with the source.Manager.
