Sebastiaan van Stijn 0573ec2b01 format (GoDoc) comments with Go 1.19 to prepare for go updates
Older versions of Go do not format these comments, so we can already
reformat them ahead of time to prevent gofmt linting failing once
we update to Go 1.19 or up.

Result of:

    gofmt -s -w $(find . -type f -name '*.go' | grep -v "/vendor/")

With some manual adjusting.

Tibor Vass 48d30b5b32 Use golang.org/x/sys/execabs
On Windows, the os/exec.{Command,CommandContext,LookPath} functions
resolve command names that have neither path separators nor file extension
(e.g., "git") by first looking in the current working directory before
looking in the PATH environment variable.
Go maintainers intended to match cmd.exe's historical behavior.

However, this is pretty much never the intended behavior and as an abundance of precaution
this patch prevents that when executing commands.
Example of commands that docker.exe may execute: `git`, `docker-buildx` (or other cli plugin), `docker-credential-wincred`, `docker`.

Note that this was prompted by the [Go 1.15.7 security fixes](https://blog.golang.org/path-security), but unlike in `go.exe`,
the windows path lookups in docker are not in a code path allowing remote code execution, thus there is no security impact on docker.

Akihiro Suda 62a15c16fc commandconn: set SysProcAttr.Setsid
Setting `Setsid` is needed for SSH connection helper with `ProxyCommand`
config, so as to detach TTY.

e.g.

  $ cat ~/.ssh/config
  Host foo
    Hostname foo
    ProxyCommand ssh -W %h:%p bastion
  $ DOCKER_HOST=ssh://foo docker run -it --rm alpine
  / #

Fix #1707
