We don't want any Supervisor lockfiles to remain on the device
when a takeLock step fails because this would interfere with the user app.

* Remove Supervisor lockfile cleanup SIGTERM listener
* Modify lockfile.getLocksTaken to read files from the filesystem
* Remove in-memory tracking of locks taken in favor of filesystem
* Require both `(resin-)updates.lock` to be locked with `nobody` UID
for service to count as locked by the Supervisor

A takeLock step should be generated before any of the following steps:
* kill
* start
* stop
* updateMetadata
* restart
* handover
ALL services in an app will be locked for any of the above actions,
unless the action is generated through Supervisor API's
`POST /v2/applications/:appId/(start|stop|restart)-service` endpoints,
in which case only the target service will be locked.
A lock will be taken for a service before it starts by creating the
directory in /tmp before the Engine creates it through bind mounts.
Also, the commit simplifies the generation of service kill
steps from network/volume changes or removals.

This commit changes a few things:
* Pass `force` to `takeLock` step directly. This allows us to remove
the `lockFn` used by app manager's action executors, setting takeLock
as the main interface to interact with the update lock module. Note
that this commit by itself will not pass tests, as no update locking
occurs where it once did. This will be amended in the next commit.
* Remove locking functions from doRestart & doPurge, as this is
the only area where skipLock is required.
* Remove `skipLock` interface, as it's redundant with the functionality
of `force`. The only time `skipLock` is true is in doRestart/doPurge,
as those API methods are already run within a lock function. We removed
the lock function which removes the need for skipLock, and in the next
commit we'll add locking as a composition step to replace the
functionality removed here.
* Remove some methods not in use, such as app manager's `stopAll`.

This commit only implements the action that a takeLock step
results in. It does not add takeLock step generation logic
to the state funnel yet.

releaseLock is a step that will be inferred if there are services
in target state, and if some of those services have locks taken by
the Supervisor.
The releaseLock composition step calls the method of the same name
in the updateLock module, which takes the exclusive process lock before
disposing all Supervisor lockfiles in the target appId.
This is half of the update lock incorporation into the state funnel, as
we also need to introduce a takeLock step which triggers during crucial
stages of device state transition.

We need the supervisor to be able to manage config.txt changes for the
RevPi Connect 4.

The message can be an empty string or similarly unhelpful, therefore
logging the entire error means that we will have whatever the message

On slower networks the default of 250ms can cause problems as all
attempts will fail rather than only the ones for interfaces that do not
actually work correctly. Increasing this timeout to 5000ms will help to
avoid these issues

Node 20 now implements the happy eyeballs algorithm as part of its core
`net` module, with the [autoSelectFamily](https://nodejs.org/docs/latest-v20.x/api/net.html#netgetdefaultautoselectfamily) option of `socket.connect`. This option defaults to `true`, meaning that a separate
implementation of happy eyeballs is no longer needed.

This also updates code to use the default import syntax instead of
`import * as` when the imported module exposes a default. This is needed
with the latest typescript version.

This updates balena lint to the latest version to enable eslint support
and unblock Typescript updates. This is a huge number of changes as the
linting rules are much more strict now, requiring modifiying most files
in the codebase. This commit also bumps the test dependency `rewire` as
that was interfering with the update of balena-lint

RPI firmware configuration allows repeating overlays to define
configurations on multiple devices. For instance, for configuring
multiple `ads` devices, `config.txt` needs to be setup this way
```
dtoverlay=ads1115,addr=0x48
dtoverlay=ads1115,addr=0x49
```
Before this change, the supervisor would interpret both lines as
belonging to the same overlay, preventing users from configuring multiple
devices, and leading to a loop when trying to apply configurations with
repeated overlays coming from the cloud side.

Rsync (v2) deltas have been broken since [Supervisor v14](460c3ba0aa). While considered legacy,
they are still used by a few customers with devices running OS < 2.47.1.
This should fix v2 delta support for those devices until we can
completely remove rsync deltas from the supervisor
