Closes #109. Multiple `Secret<T>` instances could previously share the same memory page. This would cause `munlock` to unlock multiple secrets at a time. With secrets aligned to page boundaries, we ensure that no two secrets can share the same page. Additionally we had detected the multiple-unlock case in Windows, which returns an error when `munlock` is called on an already-unlocked page. We swallowed errors in this case, but with this change we no longer need to do so.
