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.

841b835b05 boot/init: update comments in switch_root 
It better describes the reasoning for the keys than the previous
"off-the-cuff" comment I left myself.

0037614821 boot/init: Use the new evdev library 
It still uses evdev internally, but first let's change the interface,
*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!

d41c454514 boot/init: Add Devices dependency type 
It's a Files dependency, but with just a bit more user friendliness when
used in an error message.

0365079e1f boot/init: Tasks restart the queue 
This is to ensure "UX-friendly" tasks gets run ASAP.

Quickly explained, this makes sure that the top tasks (e.g. Splash) gets
ran as soon as possible.

Given the list:

 - Splash
 - Graphics
 - AAA
 - BBB
 - CCC

If `Graphics` ends up running, and AAA, BBB and CCC can too, Splash will
have to wait until all those tasks got ran once!

Not ideal for UX, if e.g. BBB takes time to *run* and we can't show the
progress to users!

The added cost of restarting the queue is minimal with tests I ran. It
was not more than a tenth of a second, and could even be rounding
errors.
