Switch drop-flag to `u8` to allow special tags to instrument state.
Refactored code so that the drop-flag values for initialized (`DTOR_NEEDED`) versus dropped (`DTOR_DONE`) are given explicit names. Add `mem::dropped()` (which with `DTOR_DONE == 0` is semantically the same as `mem::zeroed`, but the point is that it abstracts away from the particular choice of value for `DTOR_DONE`). Filling-drop needs to use something other than `ptr::read_and_zero`, so I added such a function: `ptr::read_and_drop`. But, libraries should not use it if they can otherwise avoid it. Fixes to tests to accommodate filling-drop.
