Implements [RFC 486](https://github.com/rust-lang/rfcs/pull/486). Fixes#19908.
* Rename `to_ascii_{lower,upper}` to `to_ascii_{lower,upper}case`, per #14401
* Remove the `Ascii` type and associated traits: `AsciiCast`, `OwnedAsciiCast`, `AsciiStr`, `IntoBytes`, and `IntoString`.
* As a replacement, add `.is_ascii()` to `AsciiExt`, and implement `AsciiExt` for `u8` and `char`.

This breaks code that looks like this:
let x = foo as bar << 13;
Change such code to look like this:
let x = (foo as bar) << 13;
Closes#17362.

According to [RFC 344][], methods that return `&[u8]` should have names ending in `bytes`. Though `include_bin!` is a macro not a method, it seems reasonable to follow the convention anyway.
We keep the old name around for now, but trigger a deprecation warning when it is used.

RFC 248? I think you meant RFC 438.
There ain’t an RFC 248, while 438 looks to be what is being referred to:

Chis Morgan has a pretty important documentation fix in #19385 and he hasn't responded in a while to that pull request so I rebased it for him
Closes#19385
This commit completes the deprecation story for the in-tree serialization
library. The compiler will now emit a warning whenever it encounters
`deriving(Encodable)` or `deriving(Decodable)`, and the library itself is now
marked `#[unstable]` for when feature staging is enabled.
All users of serialization can migrate to the `rustc-serialize` crate on
crates.io which provides the exact same interface as the libserialize library
in-tree. The new deriving modes are named `RustcEncodable` and `RustcDecodable`
and require `extern crate "rustc-serialize" as rustc_serialize` at the crate
root in order to expand correctly.
To migrate all crates, add the following to your `Cargo.toml`:
[dependencies]
rustc-serialize = "0.1.1"
And then add the following to your crate root:
extern crate "rustc-serialize" as rustc_serialize;
Finally, rename `Encodable` and `Decodable` deriving modes to `RustcEncodable`
and `RustcDecodable`.

cannot use an `as` expression to coerce, so I used a one-off function
instead (this is a no-op in stage0, but in stage1+ it triggers
coercion from the fn pointer to the fn item type).

parse_ty() no longer takes a boolean parameter. quote_ty! implementation has not yet been modified accordingly.
As a matter of fact, quote_ty! was not covered by tests. One test (called qquotes) references it, but it has been ignored for nearly one year and now need heavy refactoring.
quote_token.rs seemed like a good place to test quote_ty!, many other quote_*! macros were asserted there.
followed by a semicolon.
This allows code like `vec![1i, 2, 3].len();` to work.
This breaks code that uses macros as statements without putting
semicolons after them, such as:
fn main() {
...
assert!(a == b)
assert!(c == d)
println(...);
}
It also breaks code that uses macros as items without semicolons:
local_data_key!(foo)
fn main() {
println("hello world")
}
Add semicolons to fix this code. Those two examples can be fixed as
follows:
fn main() {
...
assert!(a == b);
assert!(c == d);
println(...);
}
local_data_key!(foo);
fn main() {
println("hello world")
}
