Auto merge of #23423 - nikomatsakis:issue-18737-trait-subtyping, r=nrc
This upcast coercion currently never requires vtable changes. It should be generalized.
This is a [breaking-change] -- if you have an impl on an object type like `impl SomeTrait`, then this will no longer be applicable to object types like `SomeTrait+Send`. In the standard library, this primarily affected `Any`, and this PR adds impls for `Any+Send` as to keep the API the same in practice. An alternate workaround is to use UFCS form or standalone fns. For more details, see <https://github.com/rust-lang/rust/issues/18737#issuecomment-78450798>.

Remove subtyping for object types and replace with an *upcast* coercion.
This upcast coercion currently preserves the vtable for the object, but
eventually it can be used to create a derived vtable. The upcast
coercion is not introduced into method dispatch; see comment on #18737
for information about why. Fixes #18737.

This removes the error case of the compression functions, the only errors that

Also introduces an extensible `Error` type instead of returning an `Option`.
The type implements a destructor so you can't destructure it.

Auto merge of #23352 - alexcrichton:stabilize-net, r=aturon
This commit performs a stabilization pass over the std::net module,
incorporating the changes from RFC 923. Specifically, the following actions were
taken:
* Extra methods on `Ipv{4,6}Addr` for various methods of inspecting the address
and determining qualities of it.
* Extra methods on `TcpStream` to configure various protocol options.
* Extra methods on `UdpSocket` to configure various protocol options.
Deprecated functionality:
* The `socket_addr` method has been renamed to `local_addr`
This commit is a breaking change due to the restructuring of the `SocketAddr`
type as well as the renaming of the `socket_addr` method. Migration should be
fairly straightforward, however, after accounting for the new level of
abstraction in `SocketAddr` (protocol distinction at the socket address level,
not the IP address).

`std::io` does not currently expose the `stdin_raw`, `stdout_raw`, or

rust-lang/rfcs#517), raw access will likely be provided using the
platform-specific `std::os::{unix,windows}` modules. At the moment we
don't expose any way to do this. As such, delete all mention of the
`*_raw` functions from the `stdin`/`stdout`/`stderr` function
documentation.
While we're at it, remove a few `pub`s from items that aren't exposed.
This is done just to lessen the confusion experienced by anyone who
looks at the source in an attempt to find the `*_raw` functions.

This change is aimed at removing unsightly `?Sized` bounds while retaining the

their arguments instead of taking them by reference, but due to the forwarding
implementations of `AsOsStr` and `AsPath` all code should continue to work as it
