Log:
- Final cleanup for now:
- main.c -> freeldr.c + cleanups and nice formatitng.
- Move out variables that were in main.c to ex\init.c or cpu.c, depending.
- Separate i386/kernel.c into i386/kiinit.c for X86-specific intiailization, and
/krnlinit.c for portable initialization across all architectures. Also move out global
variables appropriately.
- main_asm.S -> cpu.S
Added:

// Ke:
//
// - FIXES:
+// * Implement invalid opcode handler (fixes some apps from crashing).
// * Get rid of KiRosPrintAddress and use KiDumpParameterImages instead.
// * Sanitize some context fields during conversions.
-// * Implement stack fault and segment fault handlers.
// * Add DR macro/save and VM macro/save.
-// * Make boot process more NT-like.
// - FEATURES:
// * Use Queued Spinlocks for scheduling and dispatching.
// * New optimized table-based tick-hashed timer implementation.
