    tests: Fix build on Visual Studio
    
    Visual Studio does not come with unistd.h, so we have to:
    -Avoid including unistd.h when on Windows
    -Include the other necessary headers that contain the things we actually
     use that are in the other posixish systems' unistd.h
    -Define sleep() to use the Windows API's Sleep funcions, where we must
     multiply the argument we pass into it by 1000.
    
    The test programs now build on Visual Studio, but there are some
    UNIXisms that need to be checked, though.
