We've seen sporadic QE failures in the timeout tests on this assertion:
assert!(kind == ErrorKind::WouldBlock || kind == ErrorKind::TimedOut);
So there's an error, but not either of the expected kinds. Adding a
format to show the kind revealed `ErrorKind::Interrupted` (`EINTR`).
For the cases that were using `read`, we can just use `read_exact` to
keep trying after interruption. For those using `recv_from`, we have to
manually loop until we get a non-interrupted result.

There are some tests that need to be disabled on CloudABI specifically,
due to the fact that the shims cannot be built in combination with
unix::ext or windows::ext. Also improve the scoping of some imports to
suppress compiler warnings.

Add peek APIs to std::net
Adds "peek" APIs to `std::net` sockets, including:
- `UdpSocket.peek()`
- `UdpSocket.peek_from()`
- `TcpStream.peek()`
These methods enable socket reads without side-effects. That is, repeated calls to `peek()` return identical data. This is accomplished by providing the POSIX flag `MSG_PEEK` to the underlying socket read operations.
This also moves the current implementation of `recv_from` out of the platform-independent `sys_common` and into respective `sys/windows` and `sys/unix` implementations. This allows for more platform-dependent implementations where necessary.

These settings can only be adjusted before bind time, which doesn't make

haven't hit a stable release yet.

Travis CI has new infrastructure using the Google Compute Engine which has both
faster CPUs and more memory, and we've been encouraged to switch as it should
help our build times! The only downside currently, however, is that IPv6 is
disabled, causing a number of standard library tests to fail.
Consequently this commit tweaks our travis config in a few ways:
* ccache is disabled as it's not working on GCE just yet
* Docker is used to run tests inside which reportedly will get IPv6 working
* A system LLVM installation is used instead of building LLVM itself. This is
primarily done to reduce build times, but we want automation for this sort of
behavior anyway and we can extend this in the future with building from source
as well if needed.
* gcc-specific logic is removed as the docker image for Ubuntu gives us a
recent-enough gcc by default.

This commit removes all unstable and deprecated functions in the standard
library. A release was recently cut (1.3) which makes this a good time for some
spring cleaning of the deprecated functions.

* Lots of core prelude imports removed
* Makefile support for MSVC env vars and Rust crates removed
* Makefile support for morestack removed

This commit is an implementation of [RFC 1184][rfc] which tweaks the behavior of
the `#![no_std]` attribute and adds a new `#![no_core]` attribute. The
`#![no_std]` attribute now injects `extern crate core` at the top of the crate
as well as the libcore prelude into all modules (in the same manner as the
standard library's prelude). The `#![no_core]` attribute disables both std and
core injection.

These methods are all covered by [RFC 1158] and are currently all available on
stable Rust via the [`net2` crate][net2] on crates.io. This commit does not
touch the timeout related functions as they're still waiting on `Duration` which
is unstable anyway, so punting in favor of the `net2` crate wouldn't buy much.
[RFC 1158]: https://github.com/rust-lang/rfcs/pull/1158
[net2]: http://crates.io/crates/net2
Specifically, this commit deprecates:
* TcpStream::set_nodelay
* TcpStream::set_keepalive
* UdpSocket::set_broadcast
* UdpSocket::set_multicast_loop
* UdpSocket::join_multicast
* UdpSocket::set_multicast_time_to_live
* UdpSocket::set_time_to_live

This commit is an implementation of [RFC 1174][rfc] which adds three new traits
to the standard library:
* `IntoRawFd` - implemented on Unix for all I/O types (files, sockets, etc)
* `IntoRawHandle` - implemented on Windows for files, processes, etc
* `IntoRawSocket` - implemented on Windows for networking types

Closes #27062
