Andrew Boie 8c524a291e x86: merge IAMCU and SYS V core arch code 
Having two parallel implementations is a maintenance issue, especially
when some strategically placed #ifdefs will suffice.

We prefer the ASM versions for SYS V, as we need complete control of
the emitted assembly for interrupt handling and context switching.
The SYS V code is far more mature. IAMCU C code has known issues with
-fomit-frame-pointer.

The only difference between the two calling conventions is that the
first three function arguments are provided in eax, edx, ecx instead
of on the stack.

Issue: ZEP-49

Title: Static IDT Support

Description:

This test verifies that the static IDT feature operates as expected.

--------------------------------------------------------------------------------

Building and Running Project:

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

    make qemu

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info

--------------------------------------------------------------------------------

Sample Output:

tc_start() - Test Nanokernel 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
***** Unhandled exception/interrupt occurred! *****
Current context ID = 0x00102c44
Faulting instruction address = 0x0010342c
Fatal task error! Aborting task.
PASS - idtTestTask.
