Add the FreeBSD specific uuid implementation. Since uuid_t is not defined as an array, but as a struct on FreeBSD, use a union with a array in order to be able to return the uuid as a bytearray. Also, added a libxl internal compile time assert macro, that is used to assert that the size of uuid_t is the same as the union used in libxl.
