- Remove ke/error.c and add its functions into ke/catch.c where they
belong.
- Create ex/error.c and move Executive functions present in ke/error.c
to it.
- Implement NtRaiseHardError and move it from ke/error.c to ex/error.c.
- Increase Exceptions Dispatched count in dispatch code and comment code
more throughly.
