      We lack a fundamental read/write primitive for the server which provides an endian and alignment safe cross platform abstraction. I.e. one which swabs bytes where necessary and reads/writes via memcpy rather than reinterpret_cast.

      This is needed to:

      • remove undefined behavior in the server
      • enable builds on big endian architectures
      • enable builds on architectures with strict alignment access
      • remove -fno-strict-aliasing from server compilation flags
