Upstart has been EOL for 8 years and isn't used by any distributions we support any more.
Additionally, this removes the "cgroups v1" setup code because it's more reasonable now for us to expect something _else_ to have set up cgroups appropriately (especially cgroups v2).

Commit 2e19a4d56b removed all other version-
conditional statements from the AppArmor template, but left this one in place.
These conditions were added in 8cf89245f5
to account for old versions of debian/ubuntu (apparmor_parser < 2.9)
that lacked some options;
> This allows us to use the apparmor profile we have in contrib/apparmor/

Those patches were from 2015/2016, and all currently supported distro
versions should now have more current versions than that. Looking at the
oldest supported versions;

Unconditionally checking for RT_GROUP_SCHED is harmful. It is one of
the options that you want inactive unless you know that you want it
active.
Systemd recommends to disable it [1], a rationale for doing so is
provided in
https://bugzilla.redhat.com/show_bug.cgi?id=1229700#c0.
The essence is that you can not simply enable RT_GROUP_SCHED, you also
have to assign budgets manually. If you do not assign budgets, then
your realtime scheduling will be affected.
If check-config.sh keeps recommending to enable this, without further
advice, then users will follow the recommendation and likely run into
issues.
Again, this is one of the options that you want inactive, unless you
know that you want to use it.

There's still some locations refering to AuFS;
- pkg/archive: I suspect most of that code is because the whiteout-files
are modelled after aufs (but possibly some code is only relevant to
images created with AuFS as storage driver; to be looked into).
- contrib/apparmor/template: likely some rules can be removed
- contrib/dockerize-disk.sh: very old contribution, and unlikely used
by anyone, but perhaps could be updated if we want to (or just removed).

The `docker` CLI currently doesn't handle situations where the current context
(as defined in `~/.docker/config.json`) is invalid or doesn't exist. As loading
(and checking) the context happens during initialization of the CLI, this
prevents `docker context` commands from being used, which makes it complicated
to fix the situation. For example, running `docker context use <correct context>`
would fail, which makes it not possible to update the `~/.docker/config.json`,
unless doing so manually.
For example, given the following `~/.docker/config.json`:
```json
{
"currentContext": "nosuchcontext"
}
```
All of the commands below fail:
```bash
docker context inspect rootless
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
docker context rm --force rootless
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
docker context use default
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
```
While these things should be fixed, this patch updates the script to switch
the context using the `--context` flag; this flag is taken into account when
initializing the CLI, so that having an invalid context configured won't
block `docker context` commands from being executed. Given that all `context`
commands are local operations, "any" context can be used (it doesn't need to
make a connection with the daemon).
With this patch, those commands can now be run (and won't fail for the wrong
reason);
```bash
docker --context=default context inspect -f "{{.Name}}" rootless
rootless
docker --context=default context inspect -f "{{.Name}}" rootless-doesnt-exist
context "rootless-doesnt-exist" does not exist
```
One other issue may also cause things to fail during uninstall; trying to remove
a context that doesn't exist will fail (even with the `-f` / `--force` option
set);
```bash
docker --context=default context rm blablabla
Error: context "blablabla": not found
```
While this is "ok" in most circumstances, it also means that (potentially) the
current context is not reset to "default", so this patch adds an explicit
`docker context use`, as well as unsetting the `DOCKER_HOST` and `DOCKER_CONTEXT`
environment variables.

Finish the refactor which was partially completed with commit
34536c498d, passing around IdentityMapping structs instead of pairs of
[]IDMap slices.
Existing code which uses []IDMap relies on zero-valued fields to be
valid, empty mappings. So in order to successfully finish the
refactoring without introducing bugs, their replacement therefore also
needs to have a useful zero value which represents an empty mapping.
Change IdentityMapping to be a pass-by-value type so that there are no
nil pointers to worry about.
The functionality provided by the deprecated NewIDMappingsFromMaps
function is required by unit tests to to construct arbitrary
IdentityMapping values. And the daemon will always need to access the
mappings to pass them to the Linux kernel. Accommodate these use cases
by exporting the struct fields instead. BuildKit currently depends on
the UIDs and GIDs methods so we cannot get rid of them yet.

The buildpack-dep image is quite large, and it looks like we only use it to
compile some C binaries, which should work fine on a regular debian image;

> If this unit gets activated, the units listed will be activated as well. If one of the other units fails to activate, and an ordering dependency After= on the failing unit is set, this unit will not be started. Besides, with or without specifying After=, this unit will be stopped if one of the other units is explicitly stopped.

> Often, it is a better choice to use Wants= instead of Requires= in order to achieve a system that is more robust when dealing with failing services.
