If restoring the terminal state fails, "echo" no longer works, which means
that anything the user types is no longer shown. The login itself may already
have succeeded, so we should not fail the command, but it's good to inform
the user that this happened, which may give them a clue why things no longer
work as they expect them to work.
With this patch:
docker login -u yourname
Password:
Error: failed to restore terminal state to echo input: something bad happened
Login Succeeded
We should consider printing instructions how to restore this manually (other
than restarting the shell). e.g., 'run stty echo' when in a Linux or macOS shell,
but PowerShell and CMD.exe may need different instructions.

we don't support empty passwords; when prompting the user for a password,
we already trim the result, but we didn't do the same for a password that's

- move trimming defaultUsername inside the if-branch, as it's the only
location where the result of the trimmed username is use.
- do the reverse for trimming argUser, because the result of trimming
argUser is used outside of the if-branch (not just for the condition).
putting it inside the condition makes it easy to assume the result is
only used locally.

This function has multiple conditional branches, which makes it harder
to see at a glance whether authConfig may be partially populated. This
patch instead returns a fresh instance for error returns to prevent any
confusion.
It also removes the named output variables, as they're now no longer used,
and the returned types should already be descriptive enough to understand
what's returned.

Running `docker login` in a non-interactive environment sometimes errors
out if no username/pwd is provided. This handling is somewhat
inconsistent – this commit addresses that.
Before:
| `--username` | `--password` | Result |
|:------------:|:------------:| ------------------------------------------------------------------ |
| ✅ | ✅ | ✅ |
| ❌ | ❌ | `Error: Cannot perform an interactive login from a non TTY device` |
| ✅ | ❌ | `Error: Cannot perform an interactive login from a non TTY device` |
| ❌ | ✅ | hangs |
After:
| `--username` | `--password` | Result |
|:------------:|:------------:| ------------------------------------------------------------------ |
| ✅ | ✅ | ✅ |
| ❌ | ❌ | `Error: Cannot perform an interactive login from a non TTY device` |
| ✅ | ❌ | `Error: Cannot perform an interactive login from a non TTY device` |
| ❌ | ✅ | `Error: Cannot perform an interactive login from a non TTY device` |
It's worth calling out a separate scenario – if there are previous,
valid credentials, then running `docker login` with no username or
password provided will use the previously stored credentials, and not
error out.
```console
cat ~/.docker/config.json
{
"auths": {
"https://index.docker.io/v1/": {
"auth": "xxxxxxxxxxx"
}
}
}
⭑ docker login 0>/dev/null
Authenticating with existing credentials...
Login Succeeded
```
This commit also applies the same non-interactive handling logic to the
new web-based login flow, which means that now, if there are no prior
credentials stored and a user runs `docker login`, instead of initiating
the new web-based login flow, an error is returned.

changes readInput() to trim whitespace. The existing code tried to be
conservative and only trimmed whitespace for username (not for password).
Passwords with leading/trailing whitespace would be _very_ unlikely, and
trimming whitespace is generally accepted.

ConfigureAuth used the readInput() utility to read the username and password.
However, this utility did not return errors it encountered, but instead did
an os.Exit(1). A result of this was that the terminal was not restored if
an error happened. When reading the password, the terminal is configured to
disable echo (i.e. characters are not printed), and failing to restore
the previous state means that the terminal is now "non-functional".
This patch:
- changes readInput() to return errors it encounters
- uses a defer() to restore terminal state

This function no longer uses the /info endpoint to resolve the registry

the (once used) special registry for Windows images, which is no longer
in use, so update the docs to reflect reality :)

The CLI currenly calls the `/info` endpoint to get the address
of the default registry to use.
This functionality was added as part of the initial Windows implementation
of the engine. For legal reasons, Microsoft Windows (and thus Docker images
based on Windows) were not allowed to be distributed through non-Microsoft
infrastructure. As a temporary solution, a dedicated "registry-win-tp3.docker.io"
registry was created to serve Windows images.
As a result, the default registry was no longer "fixed", so a helper function
(`ElectAuthServer`) was added to allow the CLI to get the correct registry
address from the daemon. (docker/docker PR's/issues 18019, 19891, 19973)
Using separate registries was not an ideal solution, and a more permanent
solution was created by introducing "foreign image layers" in the distribution
spec, after which the "registry-win-tp3.docker.io" ceased to exist, and
removed from the engine through docker/docker PR 21100.
However, the `ElectAuthServer` was left in place, quoting from that PR;
> make the client check which default registry the daemon uses is still
> more correct than leaving it up to the client, even if it won't technically
> matter after this PR. There may be some backward compatibility scenarios
> where `ElectAuthServer` [sic] is still helpful.
That comment was 5 years ago, and given that the engine and cli are
released in tandem, and the default registry is not configurable, we
can save the extra roundtrip to the daemon by using a fixed value.
This patch deprecates the `ElectAuthServer` function, and makes it
return the default registry without calling (potentially expensie)
`/info` API endpoint.

Commit f32731f902 fixed a potential panic
when an error was returned while trying to get existing credentials.
However, other code paths currently use the result of `GetDefaultAuthConfig()`
even in an error condition; this resulted in a panic, because a `nil` was
returned.

Enable inspection (aka "shallow pull") of images' manifest info, and
also the creation of manifest lists (aka "fat manifests").
The workflow for creating a manifest list will be:
`docker manifest create new-list-ref-name image-ref [image-ref...]`
`docker manifest annotate new-list-ref-name image-ref --os linux --arch
arm`
`docker manifest push new-list-ref-name`
The annotate step is optional. Most architectures are fine by default.
There is also a `manifest inspect` command to allow for a "shallow pull"
of an image's manifest: `docker manifest inspect
manifest-or-manifest_list`.
To be more in line with the existing external manifest tool, there is
also a `-v` option for inspect that will show information depending on
what the reference maps to (list or single manifest).

The current implementation of the ElectAuthServer doesn't handle well when the
default Registry server is not included in the response from the daemon Info
endpoint.
That leads to the storage and usage of the credentials for the default registry
(`https://index.docker.io/v1/`) under an empty string on the client config file.
Sample config file after a login via a Docker Daemon without Registry
information:
```json
{
"auths": {
"": {
"auth": "***"
}
}
}
```
That can lead to duplication of the password for the default registry and
authentication failures against the default registry if a pull/push is performed
without first authenticating via the misbehaving daemon.
Also, changes the output of the warning message from stdout to sdterr as
per dnephin suggestion.
