Mostly just name changes that should not change behavior, apart
from ioutil.ReadDir -> os.ReadDir avoiding per-item lstat(2) in
one case.

Dependabot was apparently not picking these up (and
several haven't had a release for a long time anyway).
Also move from github.com/go-check/check to its newly
declared (and go.mod-enforced) name gopkg.in/check.v1.

The necessary images have been manually copied over to quay. Code was
updated with centralized constants for the utilized images. Tests then
all reference the constants (in case the image locations need to change
again).

Add a --all/-a flag to instruct us to attempt to copy all of the
instances in the source image, if the source image specified to "skopeo
copy" is actually a list of images. Previously, we'd just try to locate
one for our preferred OS/arch combination.
Add a couple of tests to verify that we can copy an image into and then
back out of containers-storage. The contents of an image that has been
copied out of containers-storage need a bit of tweaking to compensate
for containers-storage's habit of returning uncompressed versions of the
layer blobs that were originally written to it, in order to be
comparable to the image as it was when it was pulled from a registry.

This makes the fixture editation more robust against typos or unexpected
changes (if the “fixture” comes from third parties, like the OpenShift
registry configuration file).
This builds from the image-signatures-rest branch for
https://github.com/openshift/origin/pull/9181 .
Testing push, pull, streaming.
Does not test working with the other Docker registries built in
Dockerfile; I will leave that to the author of that code :)
Note that this relies on an internet connection for pulling from the
Docker Hub (which is incidentally tested by that); pushing to no Docker
Registry, neither local nor Hub, is tested by this.
The tests only run in a container because the (oc login) / (docker
login)-like code modifies files in a home directory; the new
SKOPEO_CONTAINER_TESTS environment variable should protect against
accidental non-container runs.
- consumeAndLogOutputs
- assertSkopeoSucceeds
- assertSkopeoFails
- runCommandWithInput
All of these allow running commands as one-liners with no call-site
error handling, making tests much more readable.
Also modifies TestNoNeedAuthToPrivateRegistryV2ImageNotFound to use
check.Matches instead of manual strings.Contains conditions, which is
shorter and more consistent with the assertSkopeo... calls.
Primarily, make it actually work; reading into a non-zero-capacity but
zero-length slice would just return 0, the goroutine would terminate,
and even the producer of the output could fail with EPIPE/SIGPIPE.
Also make the logged output readable, converting it into a string
instead of a series of hexadecimal byte values.
This will be used also by non-signing tests.
No code changes besides removing the initial capital letter in the
function name; this is a separate commit only to make reviewing of
future changes to this function easier.
