Test Version of SIV and Test Result files

I have extended SIV to have a have a command line test option to check the APIC
is as expected.  To run this new test the command is:
   wine siv -save=[wine-apic]=stdout
Within this .ZIP file apic-real.txt shows the output from a real windows
system, apic-wine.txt showing the results from my wine system which was built
from today's GIT and siv.exe is the test program

The general test loop is run 128K times and it uses SetThreadAffinityMask() to
change to a different CPU, read the CPU APIC and check it is as expected. The
1st time uses a work thread and the actual thread handle, the 2nd test also
uses a work thread but the Pseudo thread handle (0xFFFFFFFE) and the final test
uses the main thread.

When a work thread is used the test currently fails, but passes when the main
thread is used.

I hope this is of help and simple enough to use.  I feel once this is passing
then it would still be a good idea to run the SIV [Test APIC] test as this uses
a work thread per CPU and may highlight issues not shown by the [wine-apic]
test.
