This change adds support for managing native applications on the host machine.
To maximize reuse of existing code, minor refactoring has been done:
+ build/container/cp options are exported, i.e. renamed and a few setters introduced for changing the values:
image.BuildOptions
container.RunOptions
container.ContainerOptions
container.CopyOptions
+ runBuild, runRun, runCopy are also renamed to RunBuild, RunRun, and RunCopy accordingly
+ All build flags and a small subset of relevant run flags and cp flags are supported.
+ The following new flags are added:
egress: Set container path to export
destination: Set local host path for app
launch: Start app after installation
in addition, the following existing flags are intercepted and handled by the app command:
iidfile
cidfile
detach
+ New environment variables are introduced for the benefit of app developers:
HOSTOS, HOSTARCH which are assigned the values of runtime.GOOS and runtime.GOARCH from go.

Add a "completion" target to install the generated completion
scripts inside the dev-container. As generating this script
depends on the docker binary, it calls "make binary" first.

It's not initialized, because there's no `docker` command installed
by default, but at least this makes sure that the basics are present
for testing.

This allows dockerMain() to return an error "as usual", and puts the
responsibility for turning that into an appropriate exit-code in
main() (which also sets the exit-code when terminating).
We could consider putting this utility in the cli package and exporting
it if would be useful for doing a similar handling in plugins.

The logic in this function is confusing; let's start make it obvious where
the error that is returned is produced,

This confused me fore a bit, because I thought the test was checking for
an actual `context.Canceled` error (which is spelled "context canceled"
with a single "l". But then I found that this was a string that's printed
as part of a test-utility, just looking very similar but with the British
spelling ("cancelled").
Let's change this to a message that's unique for the test, also to make it
more grep'able.

This error didn't do a great job at formatting. If a StatusError was
produced without a Status message, it would print a very non-informative
error, with information missing.
Let's update the output:
- If a status-message is provided; print just that (after all the
status code is something that can be found from the shell, e.g.
through `echo $?` in Bash).
- If no status-message is provided: print a message more similar to
Go's `exec.ExecError`, which uses `os.rocessState.String()` (see [1]).
Before this patch, an error without custom status would print:
Status: , Code: 2
After this patch:
exit status 2
In situations where a custom error-message is provided, the error-message
is print as-is, whereas before this patch, the message got combined with
the `Status:` and `Code:`, which resulted in some odd output.
Before this patch:
docker volume --no-such-flag
Status: unknown flag: --no-such-flag
See 'docker volume --help'.
Usage: docker volume COMMAND
Manage volumes
Commands:
create Create a volume
inspect Display detailed information on one or more volumes
ls List volumes
prune Remove unused local volumes
rm Remove one or more volumes
update Update a volume (cluster volumes only)
Run 'docker volume COMMAND --help' for more information on a command.
, Code: 125
With this patch, the error is shown as-is;
docker volume --no-such-flag
unknown flag: --no-such-flag
See 'docker volume --help'.
Usage: docker volume COMMAND
Manage volumes
Commands:
create Create a volume
inspect Display detailed information on one or more volumes
ls List volumes
prune Remove unused local volumes
rm Remove one or more volumes
update Update a volume (cluster volumes only)
Run 'docker volume COMMAND --help' for more information on a command.
While the exit-code is no longer printed, it's still properly handled;
echo $?

Trying to make the logic slightly clearer, and adding a custom
message for the skip,
Before this:
=== RUN TestSplitCpArg/absolute_path_with_drive
cp_test.go:184: tc.os == "windows" && runtime.GOOS != "windows" || tc.os == "linux" && runtime.GOOS == "windows"
After this:
=== RUN TestSplitCpArg/absolute_path_with_drive
cp_test.go:184: skipping windows test on non-windows platform
