XINUTEST and XINUDEBUG flags

For lab 1, you do not have to use any macros in general.

However, from lab 2 onward, all print statements (e.g. kprintf(...)) should be wrapped by a macro.

Specifically, you should

1. wrap problem-related output with the XINUTEST macro. This is for our testing purposes.
2. wrap your debugging output with the XINUDEBUG macro. This for your own testing/debugging purposes.
