This avoids having a redundant `env_file` entry

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;

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.

… as it is possible to do it when interpolating. It also fixes when
there is 2 variables on the same *value* (in the composefile, on the
same line)
Finaly, renaming the default, used in cli, pattern to `defaultPattern`
to not be shadowed unintentionally.

It allows to get easily all the variables defined in a
composefile (the `map[string]interface{}` representation that
`loader.ParseYAML` returns at least) and their default value too.
This commit also does some small function extract on substitution
funcs to reduce a tiny bit duplication.

This should make it easier for people to write custom composefile
parser without duplicating too much code. It takes the default
transformers and any additional number of transformer for any
types. That way it's possible to transform a `cli/compose` map into a
custom type that would use some of `cli/compose` types and its own.

Even though those fields are not supported by `docker stack deploy`
they are defined in versions `3.x` of compose schema, so the `compose`
package should be able to marshal/unmarshal them.

- Add the possibility to skip interpolation
- Add the possibility to skip schema validation
- Allow customizing the substitution function, to add special cases.

> Run an init inside the container that forwards signals and reaps

This is supported on `run` and now on Swarm services too, so it's also
possible to have in on a composefile :).

That field is automaticaly populated with any `x-*` field in the yaml.
And marshalling the compose config struct put them back into place.
This make it possible to get those extra fields without re-inventing
the wheel (i.e. reimplementing 80% of the `cli/compose/*` packages.
Signed-off-by: Vincent Demeester <vincent@sbr.pm>
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.
