Peter Wemm c692fbe091 At great personal risk, add a __packed and __aligned(x) define that
expand to __attribute__((packed)) and __attribute__((aligned(x)))
respectively.  Replace the handful of gcc-ism's that use
__attribute__((aligned(16))) etc around the kernel with __aligned(16).

There are over 400 __attribute__((packed)) to deal with, that can come
later.  I just want to use __packed in new code rather than add more
gcc-ism's.
