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.

Move all the functions that control IRQ lines to the PIC driver. This
allows the IDT controller to handle only raw interrupts no matter where
they come from.
