Use /bin/sh in the examples, as it's more likely to be present in a
container than bash (some users got confused by this, so using plain
"sh" in the examples could lead to less confusion).
Also added some extra wording around defaults, and how they're inherited
by the exec'd process.
It's definitely not "perfect" yet (lots to do in this document to improve
it), but it's a start :)

Update the example output to not use deprecated storage drivers or
Windows versions.
Also removes the section about `--debug`, because the `docker info` output
depends on the _daemon_ (not the client) to have debug mode enabled.

using latest ubuntu LTS, and alpine for some examples. Also syncing some
wording between the man-pages and online docs.

Some touch-ups in the attach reference and man-page;
- remove uses of old images (ubuntu 14.04)
- adds some more wording about `-i` and `-t` to use the detach sequence.
- use `--filter` instead of `grep` to list the container, to make the
example more portable.

Docker v1.12 is really old, so no need to continue including this
in the docs. Also reformatted a markdown table.

This allows us to pin to a specific version of Alpine, in case the
golang:alpine image switches to a newer version, which may at times
be incompatible, e.g. see https://github.com/moby/moby/issues/44570

Make sure that the container has multiple port-mappings to illustrate
that only the given port is matched.

- use strings.Cut
- don't use nat.NewPort as we don't accept port ranges
- use an early return if there's no results

if a context is set (e.g. through DOCKER_CONTEXT or the CLI config file), but
wasn't found, then a "stub" context is added, including an error message that
the context doesn't exist.

This updates `docker context ls` to:
- not abort listing contexts when failing one (or more) contexts
- instead, adding an ERROR column to inform the user there was
an issue loading the context.

This allows commands that don't require a client connection (such as `context use`)

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.

This internalizes constructing the Client(), which allows us to provide
fallbacks when trying to determin the current API version.

On termios platforms, interrupt signals are not generated in raw mode terminals
as the ISIG setting is not enabled. Remove interrupt handler as it does nothing
for raw mode and prevents other uses of INT signal with this library.
This code seems to go back all the way to moby/moby#214 where signal handling was
improved for monolithic docker repository. Raw mode -ISIG got reintroduced in
https://github.com/moby/moby/commit/3f63b878076, but the INT handler was left
behind.

As a stepping-stone towards switching to go modules, we're switching the
versioning scheme to be SemVer(ish) instead of CalVer. Note that this
currently still is `+incompatible` version, as changing to a version > 1
requires the module to be renamed, but changes in that area will arrive
in a future release.
