cod4map: reconstructing the Call of Duty 4 BSP compiler

cod4map reconstructs the BSP compiler shipped with the 2007 Call of Duty 4 mod tools from its executable. Its C and C++ source builds a 32-bit Windows cod4map.exe; the project uses x87-oriented compiler flags because SSE2 floating-point generation changes BSP output bytes.
