Create a generic interface for drivers to make use of interrupt vectors.
This API should be platform-agnostic enough to allow any driver to make
use of virtually any interrupt vector on any CPU. On x86, the first 32
interrupts are set aside for CPU exceptions, and interrupt 128 is set
aside for system calls.

Clean up everything in the i386 arch directory. This code has been in
dire need of refactoring for a long while. All the inline assembly
functions and the data structures related to the architecture should be
placed into their own header file. Now the scheduler can access
registers and ISRs without having to deal with arch-specific code.

The x86 system call/interrupt handlers should be refactored to be more
readable.
