This was originally used to set up the guessing game, but that no longer
exists. This version uses `old_io`, and updating it involves talking
about `&mut` and such, which we haven't covered yet. So, for now, let's
just remove it.
Fixes#23760
The collections debug helpers no longer prefix output with the
collection name, in line with the current conventions for Debug
implementations. Implementations that want to preserve the current
behavior can simply add a `try!(write!(fmt, "TypeName "));` at the
beginning of the `fmt` method.
[breaking-change]
curl's progress meter would otherwise interfere with sudo's password prompt.
In addition, add the -f flag to make sure 4xx status codes are treated as errors.

The Send bound is an unnecessary restriction, and though provided as a convenience, can't be removed by downstream code.
The removal of this bound is a [breaking-change] since it removes an implicit Send bound on all `E: Error` and all `Error` trait objects.
To migrate, consider if your code actually requires the Send bound and, if so, add it explicitly.
Fixes#23774

Previously a panic was generated for recursive prints due to a double-borrow of
a `RefCell`. This was solved by the second borrow's output being directed
towards the global stdout instead of the per-thread stdout (still experimental
functionality).
After this functionality was altered, however, recursive prints still deadlocked
due to the overridden `write_fmt` method which locked itself first and then
wrote all the data. This was fixed by removing the override of the `write_fmt`
method. This means that unlocked usage of `write!` on a `Stdout`/`Stderr` may be
slower due to acquiring more locks, but it's easy to make more performant with a
call to `.lock()`.
Closes#23781

This isn't really possible to test in an automatic way, since the only traits
you can negative impl are `Send` and `Sync`, and the implementors page for
those only exists in libstd.
Closes#21310
`std::dynamic_library` is currently using `std::old_io::Path` specifically. This change brings the API in alignment with `std::fs::File` by having it take `std::path::AsPath`. The Windows code should work, but I admittedly haven't tried it (I don't have a Windows machine readily available right now).

When testing whether a default method predicates are satisfiable,
combine normalization with this check so that we also skip the
default method if normalization fails. Fixes#23485.
r? @nrc (I tried to address your nit from before as well)
Fixes#11794
I mostly removed superflous examples which use the standard library.
I have one more quesiton here though: threads. They're mostly a library thing, at this point, right?
