- add test-coverage for the function's behavior (including whitespace handling),
and use sub-tests.
- improve error-message to use uppercase for "IP", and to use a common prefix.

The ParseLink() function has special handling for legacy formats;

This patch adds a test-case for this format. While updating, also switching
to use gotest.tools assertions.

Make sure we validate the default address given before using it, and
combine the parsing/validation logic so that it can be reused.
This patch also makes the errors more consistent, and uses pkg/errors
for generating them.

Re-order some test-cases to make it easier to find if we cover all variants,
and add some missing variants.
Also change tests to not use default ports where needed, so that we are sure
the code is taking the provided value, and didn't fall back to use the defaults.

this workaround.

This was added in 683766613a, to workaround
changes in error between go 1.12.8 / go 1.11.13, causing the test to fail.
We no longer test against those versions, so we can remove this workaround.

There was a discrepancy between what `ParseTCPAddr()` accepted, and what the
daemon was able to use, resulting in the daemon to start, but fail to create
listeners for the specified host.
Before this patch:

This was originally added to solve a CLI usability issue related to `docker-machine` and `docker` (explicitly *not* `dockerd`) -- the "docker/cli" repository has a separate copy of this entire `opts` package, so isn't even using this implementation.

After moving libnetwork to this repo, we need to update all the import
paths for libnetwork to point to docker/docker/libnetwork instead of
docker/libnetwork.
This change implements that.

This prevents consumers of the opts package to also having to
depend on daemon/network, and everything related.
We can probably change some of the other constants to strings,
for easier concatenating, and need to review the windows-specific
"127.0.0.1" (instead of "localhost"), which may no longer be
needed.

Docker Desktop (on MAC and Windows hosts) allows containers
running inside a Linux VM to connect to the host using
the host.docker.internal DNS name, which is implemented by
VPNkit (DNS proxy on the host)
This PR allows containers to connect to Linux hosts
by appending a special string "host-gateway" to --add-host
e.g. "--add-host=host.docker.internal:host-gateway" which adds
host.docker.internal DNS entry in /etc/hosts and maps it to host-gateway-ip
This PR also add a daemon flag call host-gateway-ip which defaults to
the default bridge IP
Docker Desktop will need to set this field to the Host Proxy IP
so DNS requests for host.docker.internal can be routed to VPNkit

The `--rootless` flag had a couple of issues:
* #38702: euid=0, $USER="root" but no access to cgroup ("rootful" Docker in rootless Docker)
* #39009: euid=0 but $USER="docker" (rootful boot2docker)
To fix#38702, XDG dirs are ignored as in rootful Docker, unless the
dockerd is directly running under RootlessKit namespaces.
RootlessKit detection is implemented by checking whether `$ROOTLESSKIT_STATE_DIR` is set.
To fix#39009, the non-robust `$USER` check is now completely removed.
The entire logic can be illustrated as follows:
```
withRootlessKit := getenv("ROOTLESSKIT_STATE_DIR")
rootlessMode := withRootlessKit || cliFlag("--rootless")
honorXDG := withRootlessKit
useRootlessKitDockerProxy := withRootlessKit
removeCgroupSpec := rootlessMode
adjustOOMScoreAdj := rootlessMode
```

Please refer to `docs/rootless.md`.
TLDR:
* Make sure `/etc/subuid` and `/etc/subgid` contain the entry for you
* `dockerd-rootless.sh --experimental`
* `docker -H unix://$XDG_RUNTIME_DIR/docker.sock run ...`
