sched: integrate into kent hierarchy
...
This is an initial, rudimentary attempt at integrating the scheduler
into the kent hierarchy. There are likely gonna be drastic changes
in the future, and i haven't even tried running the whole thing.
But hey, the code compiles again now!

printk: introduce temporary buffer

This is just a proof of concept for now, i am perfectly aware of the
fact that this will cause buffer overruns if the line gets too long.

piss off capitalism
...
Ardix is being relicensed to GPL v3 or later. I have no idea whether you
can just do this if you feel like it or if it has any consequences, but
i kinda don't really care that much about it. Any changes made after
this commit will definitely fall under the GPL though, and considering
that only few things are really working yet anyways this is good enough
for me.

Living as a sheep herder on a lonely island is becoming an increasingly
appealing option the more i am exposed to my stupidity and inability
to memorize the return values of basic libc functions that i even
implemented myself two fucking months ago.

I have no idea what the FUCK the Engineers at ARM were thinking when
they decided to disable EVERY SINGLE FUCKING CPU COMPONENT on system
reset, except the FUCKING WATCHDOG. But this change will prevent the
system from randomly firing a watchdog reset.
