When a blob does not exist locally, rather than erroring on info
lookup, inherit the parent distribution sources. Push is able
to succeed even if the blob does not exist locally when a cross
repository mount is done. This is a common operation pushing a
multi-platform image to the same registry but different namespace.

The reference/docker package was a fork of github.com/distribution/distribution,
which could not easily be used as a direct dependency, as it brought many other
dependencies with it.
The "reference' package has now moved to a separate repository, which means
we can replace the local fork, and use the upstream implementation again.
The new module was extracted from the distribution repository at commit:

From the Go docs:
"For a nil slice, the number of iterations is 0." [1]
Both `info.RootFS` and `host.clientPairs` are slices. Therefore, an
additional nil check for before the loop is unnecessary.

Go deprecation comments must be formatted to have an empty comment line before
them. Fix the formatting to make sure linters and editors detect that these
are deprecated.

This makes it possible to check whether content didn't actually need to
be pushed to the remote registry and was cross-repo mounted or already
existed.

OCI added support for a `data` field in a descriptor.
This field is expected to contain the content being pointed to by the
descriptor.

In the refactor from 926b9c72f61b5be6bf8d952512f1d0932fbaf898, the error
handling was substantially reworked, and changed the types of errors
returned.
Notably, in the case of a network error, instead of propogating the
error through to return from pushWriter.Write (as previously), it would
be propagated through to pushWriter.Commit - however, this is too late,
since we've already closed the io.Pipe by the time we would have reached
this function. Therefore, we get the generic error message "io:
read/write on closed pipe" for *every network error*.
This patch corrects this behavior to ensure that the correct error
object is always returned as early as possible, by checking the error
result after writing and detecting a closed pipe.
Additionally, we do some additional hardening - specifically we prevent
falling through when resetting the content or detecting errors, and
update the tests to explicitly check for the ErrReset message.

Before this required a full content.Store so that it could annotate
distribution sources.
With this change PushContent can be used with just a content.Provider.
If the content.Provider is also a content.Manager then distribution
sources will be updated accordingly.
This allows people to use this function with a significantly
implementation.

Fetching blobs without foreknown descriptors is useful for using a registry as a general-purpose CAS.
