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 patch adds additional information to the Client section of the output.
We were already outputting versions of CLI Plugins, and the Server, but not
for the Client.
Adding this information can help with bug-reports where the reporter only
provided the `docker info` output, or (e.g.) only `docker --version`. The
platform name helps identify what kind of builds the user has installed
(e.g. docker's docker-ce packages have "Docker Engine - Community" set
for this), although we should consider including "packager" information
as a more formalized field for this information.

Of both "--quiet" and "--format" are set, --quiet takes precedence. This
patch adds a warning to inform the user that their custom format is not
used:

docker ps --format='{{.Image}}' --quiet
WARNING: Ignoring custom format, because both --format and --quiet are set.

The warning is only shown if the format is set using the "--format" option.

Previously, the formatter would ignore the quiet option if a custom format
was passed; this situation was handled in runPs(), where custom formats
would only be applied if the quiet option was not set, but only if the
format was set in the CLI's config.
This patch updates NewContainerFormat() to do the same, even if a `--format`
was passed on the command-line.
This is a change in behavior, so may need some discussion; possible alternatives;
- produce an error if both `--format` and `--quiet` are passed
- print a warning if both are passed (but use the logic from this patch)

These were deprecated in 6c400a9c2009bba9376ad61ab59c04c1ad675871 (docker 19.03),
but the "Deprecated:" comments were missing a newline before them.
While most IDEs will detect such comments as "deprecated", pkg.go.dev and linters
will ignore them, which may result in users not being aware of them being deprecated.
This patch;
- Fixes the "Deprecated:" comments.
- Changes the var aliases to functions, which is slightly more boilerplating,
but makes sure the functions are documented as "function", instead of shown
in the "variables" section on pkg.go.dev.
- Adds some punctuation and adds "doc links", which allows readers to navigate
to related content on pkg.go.dev.

On Windows, ignore all variables that start with "=" when building an
environment variables map for stack.
For MS-DOS compatibility cmd.exe can set some special environment
variables that start with a "=" characters, which breaks the general
assumption that the first encountered "=" separates a variable name from
variable value and causes trouble when parsing.
These variables don't seem to be documented anywhere, but they are
described by some third-party sources and confirmed empirically on my
Windows installation.
Useful sources:
https://devblogs.microsoft.com/oldnewthing/20100506-00/?p=14133https://ss64.com/nt/syntax-variables.html
Known variables:
- `=ExitCode` stores the exit code returned by external command (in hex
format)
- `=ExitCodeAscii` - same as above, except the value is the ASCII
representation of the code (so exit code 65 (0x41) becomes 'A').
- `=::=::\` and friends - store drive specific working directory.
There is one env variable for each separate drive letter that was
accessed in the shell session and stores the working directory for that
specific drive.
The general format for these is:
`=<DRIVE_LETTER>:=<CWD>` (key=`=<DRIVE_LETTER>:`, value=`<CWD>`)
where <CWD> is a working directory for the drive that is assigned to
the letter <DRIVE_LETTER>
A couple of examples:
`=C:=C:\some\dir` (key: `=C:`, value: `C:\some\dir`)
`=D:=D:\some\other\dir` (key: `=C:`, value: `C:\some\dir`)
`=Z:=Z:\` (key: `=Z:`, value: `Z:\`)
`=::=::\` is the one that seems to be always set and I'm not exactly
sure what this one is for (what's drive `::`?). Others are set as
soon as you CD to a path on some drive. Considering that you start a
cmd.exe also has some working directory, there are 2 of these on start.
All these variables can be safely ignored because they can't be
deliberately set by the user, their meaning is only relevant to the
cmd.exe session and they're all are related to the MS-DOS/Batch feature
that are irrelevant for us.

The "docker context show" command is intended to show the currently configured
context. While the context that's configured may not be valid (e.g., in case
an environment variable was set to configure the context, or if the context
was removed from the filesystem), we should still be able to _show_ the
context.
This patch removes the context validation, and instead only shows the context.
This can help in cases where the context is used to (e.g.) set the command-
prompt, but the user removed the context. With this change, the context name
can still be shown, but commands that _require_ the context will still fail.
