  add initial CMake and Visual Studio build support
  
  This moves the compatibility include files from include to
  include/compat so we can use the awful MS C compiler
  <../include/> trick to emulate the GNU #include_next extension.
  
  This also removes a few old compat files we do not need anymore.
