Log:
[FREELDR]
Convert most of the trap and blue screen code from asm to C, use KTRAP_FRAME and KSPECIAL_REGISTERS on the stack, instead of using a bunch of global variables. Convert multiply used asm code chunks into macros. Use intel syntax for remaining asm.
135 lines of C + 178 lines of asm, instead of 942 lines of asm
