caught by golangci-lint;

Detect Windows absolute paths on non-Windows CLI
When deploying a stack using a relative path as bind-mount
source in the compose file, the CLI converts the relative
path to an absolute path, relative to the location of the
docker-compose file.

This causes a problem when deploying a stack that uses
an absolute Windows path, because a non-Windows client will
fail to detect that the path (e.g. `C:\somedir`) is an absolute
path (and not a relative directory named `C:\`).

The existing code did already take Windows clients deploying
a Linux stack into account (by checking if the path had a leading
slash). This patch adds the reverse, and adds detection for Windows
absolute paths on non-Windows clients.

The code used to detect Windows absolute paths is copied from the
Golang filepath package;
1d0e94b1e1/src/path/filepath/path_windows.go (L12-L65)

Fix substitution with non-empty env-var
Due to a typo, substitution would not work if the given
environment-variable was set.

Given the following docker compose file;

```yaml
version: "3.7"

services:
  app:
    image: nginx:${version:-latest}
```

Deploying a stack with `$version` set would ignore the `$version`
environment variable, and use the default value instead;

```bash
version=alpine docker stack deploy -c docker-compose.yml foobar

Creating network foobar_default
Creating service foobar_app

docker service ls

ID                  NAME                MODE                REPLICAS            IMAGE               PORTS
rskkjxe6sm0w        foobar_app          replicated          1/1                 nginx:latest
```

This patch also fixes "soft default" not detecting empty environment variables,
only non-set environment variables.

Allow `x-*` extension on 3rd level objects
As for top-level key, any 3rd-level key which starts with `x-` will be
ignored by compose. This allows for users to:
* include additional metadata in their compose files
* create YAML anchor objects that can be re-used in other parts of the config

This matches a similar feature in the swagger spec definition:
https://swagger.io/specification/#specificationExtensions

This means a composefile like the following is valid

```
verison: "3.7"
services:
  foo:
    image: foo/bar
    x-foo: bar
network:
  bar:
    x-bar: baz
```

It concerns services, volumes, networks, configs and secrets.

Since go 1.7, "context" is a standard package. Since go 1.9,
x/net/context merely provides some types aliased to those in
the standard context package.

The changes were performed by the following script:

for f in $(git ls-files \*.go | grep -v ^vendor/); do
	sed -i 's|golang.org/x/net/context|context|' $f
	goimports -w $f
	for i in 1 2; do

			/\t"context"$/ {e=0;}
			{if (e) {print ""; e=0}; print;}' < $f > $f.new && \
				mv $f.new $f
		goimports -w $f
	done

Preserve sort-order of extra hosts, and allow duplicate entries
Extra hosts (`extra_hosts` in compose-file, or `--hosts` in services) adds
custom host/ip mappings to the container's `/etc/hosts`.

The current implementation used a `map[string]string{}` as intermediate
storage, and sorted the results alphabetically when converting to a service-spec.

As a result, duplicate hosts were removed, and order of host/ip mappings was not
preserved (in case the compose-file used a list instead of a map).

According to the **host.conf(5)** man page (http://man7.org/linux/man-pages/man5/host.conf.5.html)

    multi  Valid values are on and off.  If set to on, the resolver
      library will return all valid addresses for a host that
      appears in the /etc/hosts file, instead of only the first.
      This is off by default, as it may cause a substantial
      performance loss at sites with large hosts files.

Multiple entries for a host are allowed, and even required for some situations,
for example, to add mappings for IPv4 and IPv6 addreses for a host, as illustrated
by the example hosts file in the **hosts(5)** man page (http://man7.org/linux/man-pages/man5/hosts.5.html):

    # The following lines are desirable for IPv4 capable hosts
    127.0.0.1       localhost

    # 127.0.1.1 is often used for the FQDN of the machine
    127.0.1.1       thishost.mydomain.org  thishost
    192.168.1.10    foo.mydomain.org       foo
    192.168.1.13    bar.mydomain.org       bar
    146.82.138.7    master.debian.org      master
    209.237.226.90  www.opensource.org

    # The following lines are desirable for IPv6 capable hosts
    ::1             localhost ip6-localhost ip6-loopback
    ff02::1         ip6-allnodes
    ff02::2         ip6-allrouters

This patch changes the intermediate storage format to use a `[]string`, and only
sorts entries if the input format in the compose file is a mapping. If the input
format is a list, the original sort-order is preserved.

Tidying up compose/loader test a bit
- Use `require` instead of `assert` when the assumption is "breaking" for the code
following. For example when asserting an error is not nil and then doing
`err.Error` on it ; if `err` is nil, the test will panic instead of fail.
- Use `assert.Len` when possible. The error message is better.

pnagy 27e8bdf32b sort secrets and configs to ensure idempotence
`docker stack deploy` keeps restarting services it doesn't need to (no changes)
because the entries' order gets randomized at some previous (de)serialization.
Maybe it would be worth looking into this at a higher level and ensure
all (de)serialization happens in an ordered collection.

This quick fix sorts secrets and configs (in place, mutably) which ensures the
same order for each run.
