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.

c4f76db65f boot/init: Handle remounting existing mounts 
This is used to ensure mount points are mounted with the right options,
if for some reason they were already mounted.

Reasons they could be mounted? They could have been required for things
like logging the boot.

7dff001d75 boot/init: Prefer running UX tasks first 
This ensures graphical progress is shown ASAP when dependencies are
equally likely to run.

Otherwise, when the graphical step was ready, and switchroot about to
run, the shell step could run before the splash. This means that, in
practice, a long running task like e2fsck could have prevented the
splash to show. It doesn't make sense to make the other tasks depend on
a splash task!

There is no intention to implement any other special-cased ordering. If
there is the need to, it might mean that there is a deficiency in the
design.

a3c8cd78e8 boot/init: Sort tasks before running them 
This is partly to reduce the amount of loops it needs to run, but mainly
to control the order rather than rely on the order they were added in.

The control of order seems weird in a dependency-based system, but it'll
be used mainly for one thing in the next commit...

bdee7cf0e0 boot/init: Removes SingletonTask special dependency 
Instead, rely on targets.

Additionally removes the "Boot" special dependency which only made sense
when it was expected that having no dependency was an error.
