What was in core/ is now moved to arch/stm34l4xxx/peripherals. This new
directory is *supposed to* to contain raw header files defining just the
pertinent register structures for the various peripherals. Peripheral
management belongs somewhere in the new `kern/..` directories. This is
not completely the case at the moment, so more refactoring needs to be
done.
What was sitting in the root has now been moved into the kern/
directory. The kern/ directory is to contain everything else
other than raw device register definitions. The root of the kern/
tree is reserved for standard library-esque headers.
The kern/<peripheral> directory contains management systems for that
peripheral. (At the moment DMA is the only peripheral with a decent
management system.) Preferably these peripheral systems should only
include their correlating header in arch/stm34l4xxx/peripherals, and
use other management systems for handling other peripherals rather
than manipulating their raw registers directly. (Though this ideal
will require much more critical mass of management systems.)

Apparently people really don't like bitfields in practice,
so I have devised a compromise to retain some readability while
using bitmasks instead by writing a regset() macro.

- The init() function renamed to on_reset()
- on_reset() now responsible for tight-looping at the end
- on_reset() now set the VTable offset to the base of the FLASH
- included exhaustive list of irqs in isrs.i
- interrupt routines by default flash a code indicating their
isr number.
- interrupt routines are weak-linked allowing the programmer
to override them at-will.
