There was a recent request [1] to mark as `#[inline]` the simple
`From::from()` functions implemented for `Error`.
Thus mark all of the existing
impl From<...> for Error {
fn from(err: ...) -> Self {
...
}
}
functions in the `kernel` crate as `#[inline]`.

[ Dropped `projection.rs` since it is in another tree and already marked
as `inline(always)` and reworded accordingly. Changed Link tag to
Gary's original message and added Suggested-by. - Miguel ]

The current implementation of `ForeignOwnable` is leaking the type of the
opaque pointer to consumers of the API. This allows consumers of the opaque
pointer to rely on the information that can be extracted from the pointer
type.
To prevent this, change the API to the version suggested by Maira
Canal (link below): Remove `ForeignOwnable::PointedTo` in favor of a
constant, which specifies the alignment of the pointers returned by
`into_foreign`.
With this change, `ArcInner` no longer needs `pub` visibility, so change it
to private.

`XArray` is an efficient sparse array of pointers. Add a Rust
abstraction for this type.
This implementation bounds the element type on `ForeignOwnable` and
requires explicit locking for all operations. Future work may leverage
RCU to enable lockless operation.
