e81ae40770 Try to only suggest implementable traits for method calls.
That is, when offering suggestions for unresolved method calls, avoid
suggesting traits for which implementing the trait for the receiver type
either makes little sense (e.g. type errors, or sugared unboxed
closures), or violates coherence.

The latter is approximated by ensuring that at least one of `{receiver
type, trait}` is local. This isn't precisely correct due to
multidispatch, but the error messages one encounters in such situation
are useless more often than not; it is better to be conservative and
miss some cases, than have overly many false positives (e.g. writing
`some_slice.map(|x| ...)` uselessly suggested that one should implement
`IteratorExt` for `&[T]`, while the correct fix is to call `.iter()`).

Closes #21420.

I’d kind of like to be able to use HashState in AnyMap, which I can’t do without a stability attribute on it. While I was at it I looked around and found a few more missing.

87eb67f4f0 rollup merge of #21854: alexcrichton/try-borrow
The existence of these two functions is at odds with our current [error
conventions][conventions] which recommend that panicking and `Result`-like
variants should not be provided together.

[conventions]: https://github.com/rust-lang/rfcs/blob/master/text/0236-error-conventions.md#do-not-provide-both-result-and-fail-variants

This commit adds a new `borrow_state` function returning a `BorrowState` enum to
`RefCell` which serves as a replacemnt for the `try_borrow` and `try_borrow_mut`
functions.

99b2bd4bfa rollup merge of #21842: alexcrichton/issue-21839
Now that associated types are fully implemented the iterator adaptors only need
type parameters which are associated with actual storage. All other type
parameters can either be derived from these (e.g. they are an associated type)
or can be bare on the `impl` block itself.

This is a breaking change due to the removal of type parameters on these
iterator adaptors, but code can fairly easily migrate by just deleting the
relevant type parameters for each adaptor. Other behavior should not be
affected.

Closes #21839

747e6b53e4 rollup merge of #21832: genbattle/doc-unicode-escapes
Unicode escapes were changed in [this RFC](28aeb3c391/text/0446-es6-unicode-escapes.md) to use the ES6 \u{00FFFF} syntax with a variable number of digits from 1-6, eliminating the need for two different syntaxes for unicode literals.

I have updated The Reference and grammar.md to reflect these changes.

For "symmetric" binary operators, meaning the types of two sides must be
equal, if the type of LHS doesn't know yet but RHS does, use that as an
hint to infer LHS' type.

7b185f9cda rollup merge of #21782: alexcrichton/issue-21771
Previously if --extern was specified it would not override crates in the
standard distribution, leading to issues like #21771. This commit alters the
behavior such that if --extern is passed then it will always override any other
choice of crates and no previous match will be used (unless it is the same path
as --extern).

425f2328d0 rollup merge of #21754: semarie/openbsd-rebased
Hi.

Here a commit in order to add OpenBSD support to rust.

- tests status:
run-pass: test result: ok. 1879 passed; 0 failed; 24 ignored; 0 measured
run-fail: test result: ok. 81 passed; 0 failed; 5 ignored; 0 measured
compile-fail: test result: ok. 1634 passed; 0 failed; 22 ignored; 0 measured
run-pass-fulldeps: test result: ok. 22 passed; 0 failed; 1 ignored; 0 measured
compile-fail-fulldeps: test result: ok. 13 passed; 0 failed; 0 ignored; 0 measured

- The current implementation of load_self function (src/libstd/sys/unix/os.rs) isn't optimal as under OpenBSD I haven't found a reliable method to get the filename of a running process. The current implementation is enought for bootstrapping purpose.

- I have disable `run-pass/tcp-stress.rs` test under openbsd. When run manually, the test pass, but when run under `compiletest`, it timeout and echo continuoulsy `Too many open files`.

- For building with jemalloc, a more recent version of jemalloc would be mandatory. See https://github.com/jemalloc/jemalloc/pull/188 for more details.
