edf2e83a20 boot/init: Work around gadget teardown errors 
Those errors are non-issues.

Tear-down should, anyway, be implemented in a library to be used in
other tools like target disk mode and a stage-2 gadget utility.

b4c603bc56 boot/init: Tear down usb gadget on kexec 
Yikes, specialized code in the kexec codepath... though this is okay for
now. Let's not over-generalize when we don't know what will be required
in the future for abstraction.

6ad92214da boot/init: switch_root can and will kexec 
This is partly complete; we need to handle the situation where **only**
stage-0 should kexec into the next system.

This is yet to be implemented, but will be done through a configuration
that transforms the current bootloader-launched stage-1 into a stage-0,
while keeping the on-disk stage-1 stage-1.

812b02dd32 boot/init: Fix partial teardown for splash 
`#quit` would leave the `@pid` variable around, which in turn meant that
calling `#kill` after would fail since the process was already gone.

2ab969db37 boot: LUKS errors are "controlled" 
This means that we shouldn't raise an exception, but rather fail
outright. The background being black means that things *failed
successfully*, as expected.

*then* change the implementation details.

00f81fa95c boot/init: Handle hung tasks 
The way we're handling them is to have a global timer that is reset at
any point a task is ran.

This gives a maximum amount of chances to any task to have its
dependencies resolve.

A minimum of 60s is given, but in reality the chances are the conditions
for trying to resolve were already present before the timeout started
counting towards that particular dependency.

Note that a long running task, when successfully ran, does not cause the
timeout to be reached.

E.g. at 10s of timeout a task is started, the loop is not executed until
the task exits. When it exits the branch followed is for a task that
ran, which means that even if the task took 70s total (which gives us 80
seconds) a timeout of 60s wouldn't apply here.

Though, please, don't make your tasks take that much time to run!
