Move the entire kernel into its own directory. Create new directories
for system commands, libraries and other required essentials for a
complete Unix-like operating system.

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.

Update all the files under arch to make use of the new libk
implementation. Most of these changes are simply path changes in include
directives.

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.

Actually install the ISR handlers to the IDT.

Remove the irq number from the irq handler. This information is already
stored in the ISR frame structure.

Call the page fault handler when a page fault occurs instead of just
dumping the registers and halting.

Add a infinite while loop just in case the "hlt" instruction fails.

Remove several preprocessor macros that serve no purpose and pollute the
source file.

The serial_writestring function is small enough and platform-agnostic,
and therefore it should be moved into the main serial header and marked
as inline.

Fix the i386's general exception handler to actually work. Fix provided
