    Runtime linker: Break m32 allocator out into its own file
    
    This makes the code a little more modular and allows the removal of some
    CPP hackery. By providing dummy implementations of of the `m32_*`
    functions (which simply call `errorBelch`) it means that the call sites
    for these functions are syntax checked even when `RTS_LINKER_USE_MMAP`
    is `0`.
    
    Also changes some size parameter types from `unsigned int` to `size_t`.
    
    Test Plan: Validate on Linux, OS X and Windows
