Auto merge of #22797 - alexcrichton:io-stdio, r=aturon
This is an implementation of RFC 899 and adds stdio functionality to the new
`std::io` module. Details of the API can be found on the RFC, but from a high
level:
* `io::{stdin, stdout, stderr}` constructors are now available. There are also
`*_raw` variants for unbuffered and unlocked access.
* All handles are globally shared (excluding raw variants).
* The stderr handle is no longer buffered.
* All handles can be explicitly locked (excluding the raw variants).
The `print!` and `println!` machinery has not yet been hooked up to these
streams just yet. The `std::fmt::output` module has also not yet been
implemented as part of this commit.
Rollup merge of #22935 - dotdash:method_attr, r=eddyb
... objects
For method calls through trait objects, we currently generate the llvm
function argument attributes using the non-opaque method signature that
still has the trait object fat pointer for the self pointer. This leads
to attributes that are plain wrong, e.g. noalias. As we don't know
anything about the concrete type of the underlying object, we must
replace the self argument with an opaque i8 pointer before applying the
attributes.
Rollup merge of #22931 - semarie:dragonfly-ino_t, r=alexcrichton
this is the same problem as openbsd (#22792).
without the patch, liblibc don't build.
@mneumann please comment.
I have encountered this problem while building some rust libs with `target=x86_64-unknown-dragonfly` (while working on #22794)

Rollup merge of #22908 - mdinger:fix_link, r=Gankro
The markdown listing the link in [StrExt::width](http://doc.rust-lang.org/std/str/trait.StrExt.html#tymethod.width) isn't being parsed properly. I'm expecting it's because the `[ ]` is across 2 lines so this changes that. This is untested though.
Rollup merge of #22907 - dotdash:static_assert_bool, r=eddyb
static_assert is documented as working on static with type `bool`, but
we currently accept it on any const static and crash when the const has
an non-integral type.
This is a breaking-change for anyone who used static_assert on types
likes i32, which happened to work but seems like an unintended
consequence of the missing error checking.
Rollup merge of #22903 - semarie:openbsd-stack, r=alexcrichton
some commits in OpenBSD OS have corrected a problem of stack position.
Now, we can adjust more accurately the page guard in rust.
@dhuseby I am not sure that bitrig have already integrated these changes (the `$OpenBSD$` header in sys/kern/kern_exec.c is too old). But when they do, you may want this patch too.

Rollup merge of #22869 - alexcrichton:stabilize-env, r=aturon
Now that the `std::env` module has had some time to bake this commit marks most
of its APIs as `#[stable]`. Some notable APIs that are **not** stable (and still
use the same `env` feature gate) are:
* `{set,get}_exit_status` - there are still questions about whether this is the
right interface for setting/getting the exit status of a process.
* `page_size` - this may change location in the future or perhaps name as well.
This also effectively closes #22122 as the variants of `VarError` are
`#[stable]` now. (this is done intentionally)

Auto merge of #22839 - lifthrasiir:better-backtrace, r=alexcrichton
Fixes #20978 for supported platforms (i.e. non-Android POSIX).
This uses `backtrace_pcinfo` to inspect the DWARF debug info and list the file and line pairs for given stack frame. Such pair is not unique due to the presence of inlined functions and the updated routine correctly handles this case. The code is modelled after libbacktrace's `backtrace_full` routine.
There is one known issue with this approach. Macros, when invoked, take over the current frame and shadows the file and line pair which has invoked a macro. In particular, this makes many panicking
macros a bit harder to inspect. This really is a debuginfo problem, and the backtrace routine should print them correctly with a correct debuginfo.

Auto merge of #22801 - huonw:crateify-lint, r=kmcallister
This pulls out the implementations of most built-in lints into a
separate crate, to reduce edit-compile-test iteration times with
librustc_lint and increase parallelism. This should enable lints to be
refactored, added and deleted much more easily as it slashes the
edit-compile cycle to get a minimal working compiler to test with (`make
rustc-stage1`) from
which is significantly faster, mainly due to avoiding the librustc build
itself.
The intention would be to move as much as possible of the infrastructure
into the crate too, but the plumbing is deeply intertwined with librustc
itself at the moment. Also, there are lints for which diagnostics are
registered directly in the compiler code, not in their own crate
traversal, and their definitions have to remain in librustc.
This is a [breaking-change] for direct users of the compiler APIs:
callers of `rustc::session::build_session` or
`rustc::session::build_session_` need to manually call
`rustc_lint::register_builtins` on their return value.
