    test/nvmm/demo: Make 'smallkern' more self-contained
    
    Provide local 'asm.h' and 'trap.h' headers (derived from NetBSD),
    extract necessary PTE_* and PSL_* defines, making 'smallkern' much more
    self-contained, which greatly reduces the needed modifications for
    porting it to DragonFly.  Moreover, it helps to keep the ported code
    working on both operating systems.
