IterBytes for IpAddr and SocketAddr
Update comment in contravariant test

The previous definition was actually describing covariance.
Fixing to describe contravariance while keeping 'static in the definition was tricky so just changed to use 'short and 'long.
Implement List's any() function

This is needed for cases where we only need to know if a list item
matches the given predicate (eg. in Servo, we need to know if attributes
from different DOM elements are equal).
auto merge of #12149 : thomaslee/rust/ipaddr_deriving_iter_bytes, r=cmr

This is a fairly trivial (but IMHO handy) change to implement IterBytes for IpAddr and SocketAddr.

I originally stumbled across this because I wanted to use a SocketAddr as a HashMap key and discovered that I couldn't do it directly. Had to impl IterBytes on a new intermediate type to work around it.
Makefile.in: --no-rpath => -C no-rpath
Remove binary field

The current comment actually describes *co*-variance.
Fixing this to describe contravariance while keeping 'static in the definition was tricky so just changed to use 'short and 'long.

I found the typo in my attempt to understand the concept of variance itself and the comment confused me. I mention this to point out that I'm new to the concept so may have still got the definition wrong, so please review with care :)

This fixes the compilation failure with `./configure --disable-rpath`
Move fourcc to HOST_CRATES

It depends on libsyntax, which is a host crate, so it can't be in the target
crates section.
Switch to `Ignore` output mode for () blocks

Move replace and swap to std::mem. Get rid of std::util

Also move Void to std::any, move drop to std::mem and reexport in
prelude.
auto merge of #11956 : edwardw/rust/issue-7556, r=cmr

Closes #7556.

Also move ``std::util::Void`` to ``std::any::Void``. It makes more sense to me.

(The fact that this flag has a large collection of suboptions qualifies it for an entry in the "Additional help" section.)
