Add a variant of home_for_io that consumes the handle. Refactor out common parts of the home_for_io variants.
Split out starting a listener from accepting incoming connections.

The Listener trait takes two type parameters, the type of connection and the type of Acceptor,
and specifies only one method, listen, which consumes the listener and produces an Acceptor.

The Acceptor trait takes one type parameter, the type of connection, and defines two methods.
The accept() method waits for an incoming connection attempt and returns the result.
The incoming() method creates an iterator over incoming connections and is a default method.

Example:

let listener = TcpListener.bind(addr); // Bind to a socket
let acceptor = listener.listen(); // Start the listener
for stream in acceptor.incoming() {
    // Process incoming connections forever (or until you break out of the loop)
}
Add PointerKind to LpDeref
Prohibit assignment to `&mut` pointers that are found in frozen or borrowed locations.

Fixes #8625.
Parse and reserve typeof keyword. #3228
Emit a better error for attempted unsafe-pointer-self. Close #8306.
std::str: Double-ended CharSplitIterator

Add new methods `.rsplit_iter()` and `.rsplitn_iter()` for &str.

Separate out CharSplitIterator and CharSplitNIterator,
CharSplitIterator (`split_iter` and `rsplit_iter`) is made double-ended
while `splitn_iter` and `rsplitn_iter` (limited to N splits) are not,
since these don't have the same symmetry.

With CharSplitIterator being double ended, derived iterators like
`line_iter` and `word_iter` are too.
compilation error regexp specific to rustc.

Fix #6887.
revisions to emacs compilation regexp, more readable and robust.
bigint: cfg(target_arch = ...) => cfg(target_word_size = ...)
bigint: remove unnecessary method implements
bigint: inlining small functions
bigint: un-ignore test_shr
bigint: Add benchmarks
extend file regexp to match files with embedded spaces.
Since we assume that GDB output is UTF-8, make sure it is so on all platforms.
Otherwise it'll choose some "appropriate" platform-specific default (e.g. CP1252 on Windows).
Un-disabled debug info tests on Windows.
Port creader.rs from oldvisit to <V:Visitor> trait API.
Remove occurrences of `oldvisit` text to improve grepping for old oldvisit.
Port middle/moves.rs from oldvisit to <V:Visitor> trait API.
