Keyboard handler works
...
You do have you make sure to read from 0x60 to make further interrupts
happen. Also I'm told this might be unreliable because you actually have
to make sure you're draining all the bytes, and this assumes only one
byte

Tests + util
...
Adds a utility function to make printing out u32's easier. Also mkaes it
possible to use the rust test harness while still compiling correct
low-level code, using #[cfg...] directives.

Use rdtsc as makeshift timer

This is janky, but it is an example of some bit of state changing with

Call assembly from rust
...
All this does is print a V to the screen, but it means caling asm from
rust works. Remember that if this were in boot.asm, it'd be now-invalid
32 bit code and calling it would cause a page fault.

Followed a tip from
http://forum.osdev.org/viewtopic.php?f=1&t=20150
about moving the location of labels around, that made the linker error
go away and it looks like that fixed the restarting problem.
This commit also adds debugging flags to the build, and adds a debug
make target with the right commands to run gdb under qemu, which I'll
probably want to do in the future.
