Flavio Ceolin 7f9cc2359e x86-32: Allow set DPL value for an exception
In order to be possible to debug usermode threads need to be able
issue breakpoint and debug exceptions. To do this it is necessary to
set DPL bits to, at least, the same CPL level.

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run


Sample Output:

tc_start() - Starting static IDT tests
Testing to see if IDT has address of test stubs()
Testing to see interrupt handler executes properly
Testing to see exception handler executes properly
Testing to see spurious handler executes properly
- Expect to see unhandled interrupt/exception message
